sinqSPS
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 for communication with the Siemens 7th Generation PLC via the Fetch-Write Protocol.
Shutter Module
This script allows the shutter at the instrument to be opened and closed as well as providing access to many status bits and messages.
epicsEnvSet("INSTR", "SQ:INSTRUMENT:") # can also be set in runScript call
require sinqSPS
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.
A simplified status value and status message is created from these fields via the logic in shutter.db.
The corresponding nicos device is located at nicos_sinq/devices/epics/shutter.py.
