Experimental Physics and
Industrial Control System

Hi,

I am trying to control a device which can get the temperature values ,I used modbus_tk under python to get the value. In order to match with EPICS, I used the support module PyDevice which is an EPICS device support for Python interpreter, When I run the st.cmd file,the complete output when the IOC boots as follows:

 ./st.cmd

​Is there any way to prevent the epics terminal from automatically displaying the values obtained?
