+# Version differences: R1.03 → R1.05
+
+What changed between CI Server **R1.03.00** (what this repo was first written for; frozen on
+branch `r1.03`, tag `r1.03-final`) and **R1.05.00** (current target of `main`).
+Each skill and manual summary is moved to R1.05 one at a time; this file is where to look for
+the changes in the meantime.
+
+Sources: the revision tables at the end of each R1.05 manual (editions dated Feb. 2026; R1.04
+editions Jan. 2025) and a read-only comparison of the installed files on the R1.03
+development machine and the R1.05 test server (2026-10-08). Status: **from docs** plus
+**verified** file lists; behaviour is not yet re-tested.
+
+## 1. Installation and files (verified, 2026-10-08)
+
+| | R1.03 (development machine) | R1.05 (test server) |
+|---|---|---|
+| Version string | `CI Server R1.03.00 (r10200M)` | `CI Server R1.05.00 (r11609M)` |
+| Program root (`TLS_ROOT_PATH`) | `C:\Program Files (x86)\Yokogawa\CIServer` | `C:\Yokogawa\CIServer` |
+| Data root (`TLS_ALLUSERS_PATH`) | `C:\Users\Public\Yokogawa\tls` | `C:\Yokogawa\CIServer\tls` (same folder as the program) |
+| Manuals | `C:\Users\Public\Yokogawa\tls\doc\EN` | `C:\Yokogawa\CIServer\tls\doc\EN` |
+| `tls_versions.lst` | all lines `R1.03.00` | 112 lines `R1.05.00`, `jython-full` `R1.04.00` |
+
+The install paths may be a choice made at install time, not a product change. Always read the
+`TLS_*` environment variables (`set TLS`) rather than assuming a path. Skills still show the R1.03 paths
+until they are re-checked.
+
+**Installed files that are new or gone** (only names that matter for engineering are listed):
+
+| Area | New in R1.05 | Gone since R1.03 |
+|---|---|---|
+| IEC 60870-5-104 and IEC 61850 drivers | New driver family `eqt*` / `eta*`: `eqt104`, `eqt850`, `eqt850dmp`, `eqtdbg`, `eqtfrcscn`, `eqtiostat`, `etaman`, `eta104*.sup`, `eta850*.sup`, `eqtini.sup`, `eqt850.icd`, `eqtfrcscn.tpl`, `eqtini.tpl` | `eqp104`, `eqp850`, `eqp850dmp`, `epa104*.sup`, `epa850*.sup` (the drivers left the `eqp` EQUIPMENT family) |
+| IEC 61850 configuration | Quick load / form programs `iec61850_line_u0104`, `iec61850_station_u0104`, `iec61850_point_u0105`, `iec61850_rcb_u0105` | — |
+| OPC UA | `opcuac_method_u0104` (OPC UA client methods), `opcuac_station_u0104`, `opcaec_station_u0104` | `opcaec_station_u0103` |
+| REST API | `jrstsrv.jar`, `jrstsrv.sup`, `jrstsrv.tpl` (RESTful API server, see IM 36K10C40 §4.2) | — |
+| Upgrade | `jupgutl.cmd`, `jmrg.jar` (merge configuration files on upgrade, IM 36K01C10 ch. 3) | — |
+| Data access | `dacbackfill.cmd`, `intimpdac.exe` (OPC DA backfill; not yet investigated) | — |
+| Graphics | `connectrdp.cmd` (Edit Module *RDP Connect* action, IM 36K10C50 §2.31) | — |
+| Authorization | `dss_ath_grp_u0104` (authorization group form/loader, new revision) | — |
+| Setup files | `fcsini.sup`, `scsini.sup`, `ugsini.sup`, `vvnetini.sup` now in `tls\sup` (were only templates in R1.03), `extjython-full.sup` | — |
+
+The R1.03 development machine also had `eqpcieng*`, `opxcieng*` and `adtlogci.sup` files that were added there
+for the sample project `CI-Eng-Sample`; they are not part of the product.
+
+## 2. Manuals (from docs)
+
+All 39 manuals were reissued (Feb. 2026). One manual is new. Most of them only added contact
+information. The table lists the ones with real changes after R1.03, with the sections named in
+the R1.04 and R1.05 revision tables.

+
+**No content change** (only contact information or wording): C20, C30, E10, E30, J20, J40,
+L10, L15, L20, L25, L30, L35, L36, L40, P10, P11, P20, P30, R20, R40. Skills based only on
+these manuals still need a quick re-test on R1.05 (installed files may differ), but their
+content is expected to hold.
+
+## 3. Re-check plan
+
+Order (biggest change first), tracked in `progress.md` under *R1.05 re-check*:
+
+1. `system-check` (paths, version string): done in the baseline.
+2. `installation-security`, `data-access`, `equipment`: real manual changes.
+3. New pyTOOLS manual (P40) and the REST API.
+4. `graphics`, `history-management`, `portal-setup`, `system-management`.
+5. All other skills: re-test the task files on R1.05, no manual change expected.
+
+The R1.05 test server is **shared with other projects**. Re-checks there are read-only unless
+the user approves a change; see "Test system" in `progress.md`.
