The first step to debugging this is to turn on asynTrace in the underlying TCP/serial driver:

 

drvAsynIPPortConfigure("JenaSerial","10.0.10.5:4001")

# Add these lines for asynTrace debugging

asynSetTraceIOMask(“JenaSerial”,0,2)

asynSetTraceMask(“JenaSerial”,0,9)

 

You will then see all characters sent to and received from the device.  This will let you know if it is communicating at all.

 

You can also load an asyn record in the IOC, connect it to JenaSerial port, and send what you know to be a valid command and see if you get a response.

Hi Joe,

 

I have a PiezoSystemJena d-Drive, their latest product, and was hoping to use the existing driver written for EDS by you and recently updated (judging by time stamps in the source files), because it says in the manual that d-Drive is using EDS2 interface.

I was wondering if you/or someone else could comment on errors and if I can use this driver. It’s emphasized in many places that the driver communicates via GPIB.

My configuration: IOC is running on linux box, connected via Ethernet to NPort5450 MOXA switch and then to d-Drive via RS232.

It seems to me that the error “Illegal field value PV: jena:m1 motor_init_record_com(): card does not exist!” may relate to PIJEDSConfig(0, "JenaSerial", 0), where asyn address is not correct. I also started to question whether I can use this driver…

Thanks for help,
