manual: IM 36K10L45-01EN title: Data Access Engineering edition: 5th Edition, Feb. 2026 (R1.05); first summarised from the 3rd Edition, Sep. 2023 (R1.03) version: R1.05 (first written for R1.03) status: from docs. R1.03 (2026-10-01): installed setup files (odbsrv.sup, opxsys.sup, opxuas.sup, ServerConfig.xml), access_start.cmd, PKI folders, processes and ports checked; OPC UA client → own OPC UA server loopback verified with CI-Eng-Sample (station CIENG_UA). R1.05 (2026-10-08, read-only on the test server): setup files (opxuas.sup, opxsys.sup, epauac_eqp.sup, opxuac_mon.sup, odbsrv.sup, dbc.sup, jrstsrv.sup, dssana.sup), ServerConfig.xml, PKI folders, processes, ports, data dictionary and dataset definitions compared with R1.03; loopback not re-run. ODBC not working on either system (ISS-008); OPC DA/A&E, RESTful API calls, methods and the imported information model from docs
Data Access Engineering (R1.05)
ACCESS Service connects CI Server data to other software: ODBC (SQL on datasets), the
RESTful API (R1.04+), OPC Classic (DA and A&E, client and server, DCOM) and OPC UA
(client and server). Section numbers refer to the 5th edition. R1.04 inserted ch. 4 (RESTful
API), so OPC chapters moved up by one compared with R1.03 (R1.03 §4–§10 = R1.05 §5–§11; in the
OPC UA client chapter R1.03 §9.5–9.11 = R1.05 §10.7–10.13). Engineering Module forms:
IM36K10E20-01EN.md. Hands-on: skill data-access.
1. ODBC (§1–§3)
- Multi-tier: ODBC application + driver manager + SimbaClient driver on the client;
SimbaServer + ACCESS Service ODBC engine (
odbsrv) on the CI Server. Read and write of existing dataset records with SQL (API level Core, SQL level minimum); datasets cannot be created or deleted over ODBC. Needs an ODBC licence. odbsrv.sup:PORT(1583),USESSL(default on; certificate%TLS_ROOT_PATH%\tls\pki\odbsrv\SampleServerCertificate.pem, keySampleServerKey.pem),REMOVE_PADDING_SPACES, trace (TRACE,VERBOSE,TRACE_FILE), hidden data (TABLE_SUPPRESSION,FIELD_SUPPRESSION,FIELD_CONCEAL, all on). Unchanged in R1.05 (verified).- Client: install the VC++ 2019 redistributable and
SimbaClientDriverxx.zipfrom the medium (install.batas administrator); define a DSN with driverCiSimbaClientDriver(64-bit) orCiSimbaClientDriver32, server IP and port 1583. SimbaServer is installed and removed with CI Server (§3.2). Delete the DSN when ODBC is no longer used. Removing Simba parts from before R1.03 is now in App. 1.2. - SQL wildcards
%/_vs. MS Office*/?: escape_and%in names with\. - Common errors (§2.3): IM003 driver missing; IM002 DSN unknown; 08S01 SimbaServer not running / port mismatch / BUS Service not reachable.
Installed (R1.03 and R1.05 test systems): odbsrv.sup PORT 1583, USESSL YES, but the
folder %TLS_ROOT_PATH%\tls\pki\odbsrv does not exist and no sample certificate is shipped, so
odbsrv stops at every start (CppServerAPI::Run() failed: InitializeSslCtx(): SSL_CTX_use_certificate_chain_file() failed, then DUR-W-REM_PROC, Process ODBSRV exited unexpectedly); port 1583 does not listen. Fix: put a certificate and key there, or set
USESSL = NO (admin; not applied, ISS-008). access_start.cmd writes the ODBC registry
defaults once (when %TLS_DAT_PATH%\access.new exists).
2. OPC Classic basics (§5)
DCOM-based, Windows only. CI Server has DA client (opxdac), DA server (opxdas12, DA 1.0A
and 2.0, custom + automation interfaces), A&E client (opxaec), A&E server (opxaes).
- Quality: OPC DA quality goes to the lower 16 bits of the CI Server quality word, OPC A&E quality to the upper 16 bits. Item to OPC: CI Server quality low byte → OPC high byte; OPC low byte = offline → LAST_KNOWN, blocked → LOCAL_OVERRIDE, not initialised → NOT_CONNECTED, else GOOD.
- Types:
VT_UI1/UI2/INT/I1/I2/I4→ Integer,VT_UI4/UINT/R4/R8→ Real,VT_BSTR→ String,VT_BOOL→ Boolean. - Items, sections and objects appear to OPC servers (DA, A&E and UA) only with OPC visible (and every parent section visible).
3. OPC DA client (§6)
- One client process per DA line (name given in the line), started/stopped with CI Server;
stop one with
durstp -msk -t10 -p <client>. Uses a save file in%TLS_SAV_PATH%named after the process; delete it (client stopped) if it gets inconsistent. - Server check every
OPXDAC_SRV_ALIVEms (default 30000); station status item: 1 running, 2 failed, 3 no config, 4 suspended, 5 test. Not connected → mapped items OFFLINE. Group status item: 1 active / 0 not active (items offline). - Setup (
<client>.sup, elseopxsys.sup; §6.3):OPXDAC_SAFE_CON(allow connecting to a CI Server DA server — never to the own node or a DURM-connected node: deadlock),OPXDAC_PING(ICMP check before DCOM, fast failure),…_PING_TIMEOUT(3 s),…_DUR_QSZ,…_HBEAT(100 ms),…_ITMBUF,…_FLUSH_GRPQUE(500 ms),…_BROWSE_CACHE,…_DISABLE_BROWSING,…_CHECK_MAPPING,…_ASYNC_WRITE,…_USE_CANONICAL_DATA_TYPE(default asks VT_R8),…_IGNORE_BAD_QC_UPDATES,…_CLEAR_SAV_FILE,…_DISABLE_STATUS_UPDATE. - Advice: one OPC server per client process (a DCOM time-out blocks the whole process).
Quick-load templates: export
LINE_DF,STATION_DF,OPC_GROUP_DF,ITEM_DF,POINT_DFof one station made in the Engineering Module. - DCOM tunnelling (§6.6): run the client on a PC in the OPC server's domain (CI Server with
BUS, DATABASE, EQUIPMENT, ACCESS licence) connected to the host by MDUR
(
durm_<n>_udp.sup, port ≥ 20000,dur.suphost node = CI Core), use DCOM tunnelling to host on the client's setup file; on the host add the line with Equipment node = tunneller node. Useintmonnode monitoring with Set slave items offline when node unavailable.
4. OPC DA server (§7)
- COM server
opxdas12.exe, ProgIDYokogawa.CIOpcDas.<version>, DUR nameOPXDAS; started by COM on the first client connect; stop withdurstp -p opxdas(clients get a shutdown). - Namespace = sections/items/sub-items (hierarchical or flat), filters (type, access, VB LIKE pattern). Cache read is fast and correct; device read blocks — use only after queue overflow. Timestamp = time written into the server cache.
opxsys.supData Access Server tab:OPXDAS_DUR_QSZ(100 kB),…_HBEAT,…_ITMBUF,OPXDAS_USER(log on as a CI Server user to apply its authorisation; empty = full access, fastest),OPXDAS_DCOM_TUN,OPXDAS_IGNORE_FTQ. Installed also:OPXDAS_SET_LOG_LEVEL(not described).- Remote access needs DCOM configuration (
dcomcnfg: authentication Connect, impersonation Identify, access/launch permissions for an OPC account; identity of the server = that account),secpol(Create permanent shared objects, Network access: Classic), firewall rules foropxdas12.exe,opxdac.exe,opcenum.exe,mmc.exeand DCOM — not needed where the IT Security Tool is applied. Same account/password on both sides in a workgroup. - Troubleshooting (§7.9):
OCSRegistryCheck.exe(GUI; installed),opxdas12 /RegServer,opccommonsetup/opcenum /RegServer/opcenum /Service(set the service to automatic),regsvr32 opcproxy.dllandopccomn_ps.dllin%WINDIR%\SysWOW64. Test locally first.
5. OPC A&E client and server (§8, §9)
- Client
opxaec(default nameOPXAEC,-nfor more), setup<name>.suporopxsys.sup(OPXAEC_SAFE_CON— same deadlock rule,…_DUR_QSZ,…_SRV_ALIVE,…_PING_TIMEOUT,…_TRACE); maps condition events to items; one server per client advised. - Server
opxaes, ProgIDYokogawa.CIOpcAes.<version>, DUR nameOPXAES; publishes items with alarm monitoring as conditions;OPXAES_ACK_ALLOWED(acknowledge from clients),…_ALM_REC_DELAY(30 s),…_BROWSE_PREP_INI, andOPXAES_EC_ATTR_*switches for the CI Server-specific event attributes (old/new value, quality, status, alarm state, item description, units, node, group, number, sub-number). Installed: all on. - Installed R1.05 only (verified 2026-10-08, not in the manual, ISS-085):
OPXAES_DIR_ALM(YES) switches "Direct" alarm events of the A&E server.
6. OPC UA client (§10)
- OPC UA TCP only; security by X.509 certificates (application authentication), user anonymous or name/password; modes None/Sign/SignAndEncrypt; policies Basic256Sha256, Aes128-Sha256-RsaOaep, Aes256-Sha256-RsaPss recommended (None, Basic128Rsa15, Basic256 not).
- Data types (§10.3.4, new in R1.04): Boolean → Boolean; SByte, Byte, Int16, UInt16, Int32,
Integer → Integer; UInt32, Int64, UInt64, Float, Double, Number, UInteger, Duration → Real; String, ByteString,
LocalizedText, DateTime / UtcTime (only
YYYY-MM-DDThh:mm:ss.sssZ) → String of up to 250 bytes; ExtensionObject only for EURange and EngineeringUnits; enumerations as Int32. Unsigned types take no negatives, 64-bit types no decimals. One array element per point (methods take no arrays). A failed conversion is logged and the item gets status Bad. OPC UA status → CI Server quality: 0 good, 1 bad, 2 uncertain. - A&C (§10.4): only with
OPXC_ENABLE_EXTENDED_FUNC = YESin the client's setup file (R1.04+, default NO). External alarms from ConditionType and derived types (ALARM/NORMAL events), other events INFORMATIONAL; filters by event type, component, event node; severity → priority table (901–1000 → 1 … 1–100 → 15), per station; don't manage NonExclusiveLimitAlarmType. - Model change events (§10.5, R1.04):
GeneralModelChangeEventis handled per change type — node/reference added: the affected points are recreated; node/reference deleted: the linked items go offline and external alarms get a ConditionRefresh; data type changed: nothing.BaseModelChangeEvent(no detail; recreate all points and event nodes) only withOPXC_BASE_MODEL_CHANGE_EVENT = YES(default NO). Bursts within 10 s are handled once, handling waits during alarm floods, and the server must support Read and Browse. - Methods (§10.6, R1.04): a CI Server object per method with attribute
MTD_KEYand signalsMTD_TRG,MTD_RET,MTD_IN_ARG_n,MTD_OUT_ARG_n(≤ 10 each; sample Java classUAC_MTD_JBASE); a method record per station and one point (namespace and node IDCIX_UAC_MTD, Input + Output) connected toMTD_TRG; symbol/display (demoAOG_UAC_Method_Demo). DatasetOPCUAC_METHOD_CALL2_DF(R1.03:OPCUAC_METHOD_CALL_IN_DF/…_OUT_DF, removed). Procedure: skilldata-access,opcua-client.md§7. - Redundancy (§10.7): no client redundancy (use HAC); servers: transparent, or non-transparent cold backup with two endpoints (Active server item 0/1/2).
- Engineering objects (§10.9): line (starts a client process; name must start with
OPX, max 11 characters), station (= session), subscription, point (= monitored item), alarm component / event type filter / event node / template settings, method. The station's communication status item is called Boolean in §10.9.2, but IM 36K10E20 4th ed. lists states 0–5 (ISS-080). - Certificates (§10.9.10): the client process creates
<host>_<PROCESS>.derin%TLS_ALLUSERS_PATH%\pki\opxuac\pkiclient\own\certs(also listed in datasetOPCUAC_PKI_CERTIFICATES_DF; verified on R1.03 and R1.05); server certificates arrive in…\pkiclient\rejectedand must be trusted (Engineering Module, or move to…\pkiclient\trusted\certs); foldersdeleted,rejectedadded by CI Server. The server must trust the client's certificate too. Expiry warnings: seeIM36K10E20-01EN.md§3. - Setup (§10.11;
<process>.sup, else the templateepauac_eqp.sup— the R1.03 edition namedopxuac.sup, which is not installed on R1.03 or R1.05, ISS-084):OPXC_DUR_QUEUE_SIZE(10000 kB), heartbeats, buffers,OPXC_COM_STAT_CHK_INTERVAL(10 s),OPXC_STATION_CON_TRY_INTERVAL(30 s; observed retries every ~35 s on R1.03),OPXC_TIMESTAMP_OPTION(SERVER/SOURCE),OPXC_LOG_LEVEL, service and session time-outs,OPXC_SERVICE_COMPLIANCE, and new in R1.04OPXC_BASE_MODEL_CHANGE_EVENT,OPXC_ENABLE_EXTENDED_FUNC(both NO). Log file%TLS_LOG_PATH%\<PROCESS>.log. - Installed R1.05
epauac_eqp.sup(verified 2026-10-08, ISS-083):OPXC_SERVICE_CALL_TIME_OUT = 60(manual default 10 s); undocumentedOPXC_DISABLE_SAV_FILE(NO),OPXC_ALARM_TIME_ATTRIBUTE(tab Alarm Time), hiddenOPXC_CERT_EXP_PERIOD_WARN(2 months).opxuac_mon.supis unchanged from R1.03 (none of the new keywords). - Quick load (§10.12–10.13):
OPCUAC_LINE_DF,…_STATION_DF,…_SUBSCRIPTION_DF,…_POINT_DF(+ alarm and method datasets). DatasetOPCUAC_TAG_DFbrowses a connected server (filter onOPC_STATION_NAMEandOPC_TAG_PATH; R1.05 addsREBROWSEandREAD_NODE_INFO). Line, station, subscription and point definitions are identical in R1.03 and R1.05 (verified). - Installed:
opxuac_mon(a monitor instance) is started byaccess_start.cmd. - Upgrade from R1.03 (App. 1.3): set
OPXC_ENABLE_EXTENDED_FUNCif A&C was used; methods driven by dataset field updates no longer work — rebuild classes (MTD_*, extended reset), symbols and displays, and re-save methods with String or Boolean input arguments. App. 1.4 (R1.05): one class name per method object.
7. OPC UA server (§11)
- Since R1.04 the server offers only Data Access and methods by default. Alarms &
Conditions, HistoryRead and PubSub need
OPXUAS_ENABLE_EXTENDED_FUNC = YESinopxuas.sup(ch. 11 intro, §11.6.2; installed default NO, verified on R1.05). An upgrade with the automatic configuration merge sets it; otherwise set it by hand if these were used (App. 1.3). - Process
OPXUAS(opxuas -n opxuas, started byaccess_start.cmd; stopdurstp -m -p opxuas), Unified Automation C++ SDK, port 34493. Log%TLS_ALLUSERS_PATH%\log\OPXUAS.logandOpxUas_Sdk*.log. - Visible data (§11.1.4): sections, objects, items with OPC visible; items also need Read
(read values, browse into the item) and Write (write values, alarm methods). Parent
sections must be visible. Without Read the item is listed but browsing into it fails
(
UncertainNotAllNodesAvailable). External alarms: OPC visible / read / write / manual reset in the station's alarm template settings. - Users (§11.1.5–11.1.6): anonymous = like
OPC_UA_SERVER_READ; authorisation actionsOPC_UA_SERVER_READ(browse, read, history) andOPC_UA_SERVER_MODIFY(+ write, methods). Anonymous access is governed by thedssana.supuser interface "Anonymous Via OPC UA Server" (OPXUASANY): installed default (R1.03 and R1.05) is no login with profileCI_NO_LOGIN_OPCUASfor local clients and Manual CI Server for remote clients. With AD integration, "Via OPC UA Server" + Automatic needs no AD password. - Address space (§11.3, now called the native information model):
Objects→ sections (folders) → objects → items (CIItemNumericType,…BooleanType,…StringType,…NumericSubType) with child nodes such asValue,Status,Blocked,Offline,HMIInfo, and alarm condition nodes. Types are inhttp://www.yokogawa.com/CI_Server/(ns 3 in the manual). CI Server entities (sections, items) are in namespaceurn:Yokogawa:CI_SERVER_OPC_UA_SERVER(verified by browsing on R1.03; the manual does not name it, ISS-032). - NodeIds are JSON strings:
{"nsid":"<namespace id>"}for the entity,{"0":"Value","nsid":"<n>"}for its value; or by name:{"0":"Value","itnm":"<item>"}(case sensitive; verified on R1.03). Thensidchanges when the item is recreated — preferitnm.OPXUAS_USE_NAME_NODEIDSmakes the server use names in its own IDs. - Status mapping: NORMAL → Good; NOT_INIT, UPD_OFF, OFFSCAN, OFFLINE, UNREACH → BadNoCommunication; BAD_VALUE → Bad. Types: Boolean, Int32, Double, String. Priority → severity: 1 → 1000, 2 → 900 … 15 → 50, 0 → 1 (since R1.03).
- History (§11.3.3; extended functions): items in a history group show HistoryRead; max 5000 values per node per call.
- Alarm methods (extended functions): Acknowledge, Confirm (= acknowledge), Disable/Enable
(force to normal); external alarms Acknowledge/Confirm passed to the source;
CIManualResetfor CENTUM. - Imported information model (§11.4, new in R1.05): a standard NodeSet file (UANodeSet 1.05
schema) is mapped to CI Server entities with the OPC UA Information Model Mapper
(
IM36K10E20-01EN.md§4) and loaded as%TLS_DAT_PATH%\<queue>_<NodeSet file>.xml(one per server process, reloaded at server start). Mapping: section/object → Object; method object (MTD_*class; sampleUAS_MTD_JBASE) → Method; item/sub-item → Variable; item alarm or external alarm → Event. OPC visible / Read / Write still apply. Once loaded, the native model is hidden unlessOPXUAS_ENABLE_OWN_MODEL_TREE(manual name…_NATIVE_MODEL_TREE) is YES. Variables: no arrays, basic types only; out-of-range values giveBadOutOfRange(item status unchanged). Method calls return OPC UA status codes (e.g.BadUserAccessDenied,BadNotExecutablewhen the item is blocked or the object not OPC visible). Rights:UA_MAPPER_PROJECT_INSERT/_MODIFY/_DELETE(inSYSTEM_MANAGER), datasetUASERVER_MAPPER_DF. opxuas.sup(§11.6): General (FTFW_*queue, heartbeat, log), OPC UA Server tab (OPXUAS_OPTIONAL_NODES,…_MODEL_CHANGE_EVENTS,…_USE_NAME_NODEIDS,…_USE_DYNAMIC_SCANRATE,…_SOURCE_TIME_STAMPS,…_USE_RAW_STATUS,…_VARIABLE_CACHE_SIZE100000,…_NUM_VALUES_PER_NODE5000, and new…_ENABLE_NATIVE_MODEL_TREE,…_ENABLE_EXTENDED_FUNC), Alarm settings (EVENTS= ALARM, ACKN, DEACT, INFO), Logging.OPXUAS_MODEL_CHANGE_EVENTSnow needs the extended functions; it sends BaseModelChangeEvents (also on NodeSet load/unload) and GeneralModelChangeEvents for root-level entities — deeper levels need an itemNodeVersion(or<process>_NodeVersion, OPC visible + Read) at that level.- Installed keyword names differ (verified R1.03 and R1.05):
OPXUAS_DYNAMIC_SCANRATE(manual…_USE_DYNAMIC_SCANRATE), extraOPXUAS_SET_HIGH_PRIO_15(ISS-034); R1.05:OPXUAS_ENABLE_OWN_MODEL_TREE(manual…_NATIVE_MODEL_TREE) and hiddenOPXUAS_METHOD_TIMEOUT_MARGIN(10000 ms) (ISS-082). ServerConfig.xml(§11.7): the manual still gives%TLS_ROOT_PATH%\tls\exe; installed R1.05 has it only in%TLS_SAV_PATH%(R1.03:tls\exe; ISS-081). Endpointopc.tcp://[NodeName]:34493; trust list…\pki\opxuas\pkiserver\trusted\certs, rejected…\pkiserver\rejected(created at the first rejection), own certificateciserveruaserver.der. Installed (R1.03 and R1.05): only Basic256Sha256, Aes128_Sha256_RsaOaep, Aes256_Sha256_RsaPss with Sign / SignAndEncrypt (no None endpoint); anonymous, user/password and certificate user tokens enabled (manual: certificate off, ISS-034);AutomaticallyTrustAllClientCertificatesfalse. The R1.05 file adds SDK sections (role configuration, user/password management, PubSub settings).- First connection of any client (§11.1.6): trust the server certificate on the client, then
move the client certificate from the server's
rejectedtotrusted\certs. UaExpert is the suggested test client. - Extra server instances (for PubSub lines or to test an information model): copy
ServerConfig.xmlto<instance>_ServerConfig.xmlwith another port, copyopxuas.supto<instance>.sup, add a start line inaccess_start.cmd; instance names start withOPX(IM 36K10E20 4th ed. §3.4). - Discovery (§11.8): LDS on 4840 only when several servers are on a host; GDS for central certificate management (concepts only).
8. RDBMS data exposure (not in this manual)
IM 36K10L45 does not describe RDBMS data exposure; it is in the Tutorial (IM 36K10G10 ch. 10)
and the item form (IM 36K10C10 §3.3). Summary here because it is an ACCESS-type interface;
tested in R1.05 only (user system, 2026-10-02; R1.03 files checked read-only and identical;
R1.05 files re-checked 2026-10-08). Procedure: skill data-access, task rdbms-exposure.md.
- Processes
DBCSND(sender, subscribes to DSS data) andDBCDEM(receiver, writes to MS SQL Server via ODBC); setup filedbc.sup(sender and receiver tabs; connection stringDEM_CONNECTION, defaultDriver={SQL Server};Server=localhost\SQLEXPRESS;…). - Exposures are records in
DATA_EXPOSURE_DF(source dataset, remote table, filterRECORDS, up to 32 field → column pairs or all fields). The target table is created by CI Server. ITEM_VALUESexposure is driven by the per-item aggregation intervalITEM_DF.AGG_INTERVAL(60 s–7 days, 0 = off): value, min, max, average, count and a local-timeTIMESTAMP(seconds since 1970) per interval.- Filter field names must not be quoted (
NAME LIKE "<Section>*"); the manual's quoted example fails and stops all exposures (ISS-057).ITEM_HISTORYexposure: manual vs installed change log disagree (ISS-058). - The CI Service account
.\CIX_PROCESSis local, so a remote SQL Server needs a SQL login and mixed mode (ISS-059).
9. RESTful API (§4, new in R1.04)
From docs; port 34597 listening and the jrstsrv.sup keywords verified on R1.05 (2026-10-08).
No request was sent.
- HTTPS server installed with CI Server and started/stopped by ACCESS Service, on a CI Core or on a CI Portal (reaching the core over MDUR). Not supported by CI View, Remote Connect or enterprise setups. Nothing to install on the client.
- Authentication: HTTP Basic (CI Server user) plus an API key sent in the
x-api-keyheader. Keys are made in the Engineering Module (Authorisation › Users, Add API Key, type RESTful API), one per user; stored in datasetAPI_KEYS_DF. jrstsrv.sup(§4.2.1):JRST_MAX_RECORDS(records per reply, default 100),JRST_USE_TWO_WAY_SSL(default off: client trusts the server's self-signed certificate in%TLS_ALLUSERS_PATH%\pki\jrstsrv\keystore),JRST_READ_ONLY_MODE(default on),JRST_NETWORK_PORT(34597),JRST_USER_CACHE_TIME(600 s, must be > 0),JRST_CUSTOM_DATASETS(user datasets with read/write rights).- Requests (§4.3.2):
https://<host>:34597/jrest/v2/<entity type>/<function>with OData options$filter,$select,$top,$skip; replies are OData JSON. Entity setsTags,EventCategories,EventRecords. Functions:GetHistory(one tag, ISO 8601 times, sample interval in s; highest-priority history group),GetHistoryMultiTag(≤ 5 tags),GetEventHistory,GetAuditInfo,GetCurrentAlarms,AcknowledgeAlarms(several per request),UpdateItems(value, optional quality and status — status must matchSTATUS_DF.NAME),ReadDatasetandDataset(PUT/PATCH/DELETE on custom datasets). - Status codes (§4.3.3): 200, 204, 400 (bad URL or no data), 401 (rights or credentials), 404, 405, 500, 503.
