@ -4,13 +4,25 @@ A collection of standardised SPS databases (or "modules") for interacting with
the control unit itself and other external hardware.
This makes use of the
[s7plcFW Epics driver](https://git.psi.ch/epics_driver_modules/s7plcFW) for
[s7plcFW Epics driver](https://gitea.psi.ch/lin-epics-modules/sinqS7plcFW) for
communication with the Siemens 7th Generation PLC via the Fetch-Write Protocol.
# Shutter Module
```
epicsEnvSet("PREFIX", "SQ:INSTRUMENT") # can also be set in runScript call
This script allows the shutter at the instrument to be opened and closed as
well as providing access to many status bits and messages.
runScript "$(sinqSPS_DIR)shutter.cmd" "SPS_IP=172.28.101.26, FETCH_DB=2000"
```
epicsEnvSet("INSTR", "SQ:INSTRUMENT:") # can also be set in runScript call
runScript("$(sinqSPS_DIR)shutter.cmd","SPS_IP=172.28.101.26,FETCH_DB=210")
```
The directly exposed database fields can be found in
[shutter.substitutions](./templates/shutter.substitutions).
A simplified status value and status message is created from these fields via
the logic in [shutter.db](./db/shutter.db).
The corresponding nicos device is located at
[nicos\_sinq/devices/epics/shutter.py](https://gitea.psi.ch/lin-instrument-computers/Nicos/src/branch/release-3.12/nicos_sinq/devices/epics/shutter.py).
