Experimental Physics and
Industrial Control System

Hello All,

 

According to the 'motor record' manual V6.1, the motor record has support built in for the PI C-862 Mercury motor controller from Physik Instrumente GmbH. It is connected via RS-232 to the IOC.

 

I am supposed to control this device via EPICS. It seems obvious to use the motor record. However, I don't have the faintest clue what to put into the 'OUT' field of the record to make it connect to the dedicated serial channel. Can anybody help me here (example, documentation, instructions, …)?

 

What I found out by doing a

  #> grep device /work/iocBoot/R3.14.8/dbd/motor-test.dbd

is that I should write 'PIC862' into the DTYP field.

Furthermore, I think I know how to configure the asyn driver in the startup script to open a serial port:

  drvAsynSerialPortConfigure ("BusC863Ctrl", "/dev/ttyS0")

  asynSetOption ("BusC863Ctrl",   0, "baud",    "9600")

  asynSetOption ("BusC863Ctrl",   0, "bits",    "8")

  asynSetOption ("BusC863Ctrl",   0, "parity",  "none")

  asynSetOption ("BusC863Ctrl",   0, "stop",    "1")

  asynSetOption ("BusC863Ctrl",   0, "clocal",  "Y")  # Y = ignore DTR/DSR

  asynSetOption ("BusC863Ctrl",   0, "crtscts", "N")  # N = ignore RTS/CTS

 

Any help appreciated.

 

Thanks and regards,

Andy
