Running IOCs

Running the IOC

Start the IOC

Either:

• start the IOC through the GUI.
  • If this is a new IOC you will need to run make iocstartups in the EPICS folder for the IOC to be displayed in the GUI.
• start the IOC through the console (ctrl + x)
• switch off/on auto start (ctrl + t)
• start the IOC by running runIOC.bat st.cmd (in iocBoot/Appdir)

IOC in procServ using the Console

Open an epics terminal a list all running instruments with

console -M localhost -x

To interact with an IOC use

console -M localhost <IOC_NAME>

console will attempt to complete the name if you only give part of it and will give you possible options. Once in the console:

• ctrl-x : starts and stops the IOC
• crtl-e c .: exits the console

Simulation Mode

TO switch an IOC to simulation mode the default is

caput <IOC PV NAME>:SIM 1

Macros

It is possible to set macros for an IOC either through the IBEX GUI or using the globals.txt file.

Globals.txt

The globals.txt is file is held in C:\Instrument\Settings\config\NDW_____\configurations in here you set macros global macros are set with <macro name>=<value> macros specific for an IOC are set with <ioc name>__<macro name>=<value>

e.g.

GALIL_01__GALILADDR=130.246.51.169
GALIL_01__MTRCTRL=2
GALIL_03__MTRCTRL=3
GALIL_03__DEVSIM=1
EGXCOLIM_01__RECSIM=1

Reading a Compressed Hex PV

Use the following to read a waveform PV of a compressed hexed string

caget -t -S <PV NAME>|uzhex

(uzhex - think unzip hex)
