Hi,

You have 2 error messages:

> drvStreamInit: Warning! STREAM_PROTOCOL_PATH not set. Defaults to "."

That error message is normal and can be ignored if you are not using Stream device in your IOC.

> TEST:CAT1:IN1 devAsynInt32::initCommon connectDevice failed asynManager:connectDevice port CAT_AI1R not found

This error is not normal, and means you probably have an error in your st.cmd file.  Please send the complete output when the IOC boots, not just the error message.

Mark

Hi,

  I am trying to use modbus on debian system to control device,

When I execute the st.cmd file,it shows the following error:

drvStreamInit: Warning! STREAM_PROTOCOL_PATH not set. Defaults to "."

TEST:CAT1:IN1 devAsynInt32::initCommon connectDevice failed asynManager:connectDevice port CAT_AI1R not found

How can I solve this problem?

Thanks,

Xiaomin
