Hello EPICS-community,

 

I have trouble connecting a Eurotherm2604 temperature controller via modbus with this EPICS-module:

https://github.com/jwlodek/eurotherm2k

A couple of months ago this package was refurbished as you can see from this tech-talk:

https://epics.anl.gov/tech-talk/2022/msg01319.php

 

I can compile the module and can build the IOC, which works fine via the EI-bisynch protocol. But I can’t establish any connection when it comes to modbus (I need the modbus protocol to read some additional info that is not implemented in EI-bisynch). FYI: the modbus communication on the very same COM-port (same cable) just works fine with the vendor software iTools. This is how my IOC-modbus startup looks like (I’m using the latest modbus-master R3-2):

Can someone help?
