Hi Mark,

 

thanks for the hint. I got it working now when I connected the Eurotherm to the Moxa NPort serial device server:

drvAsynIPPortConfigure("EMODBUS","nport1:4008",0,0,1)

 

After all, it was setting the link type to 1=RTU, second argument in this line:

modbusInterposeConfig(EMODBUS, 1, 2000, 0)

 

I thought that when I’m using “drvAsynIPPortConfigure” the link type has to be 0=TCP because the serial device server converts the serial port to a TCP/IP port...

 

Michael

Hi Michael,

 

I know very little about these controllers.  But looking at the catalog here https://eurothermonline.com/controllers/eurotherm-2408.html for one model, it seems that the communications option is specified when ordering, and there are lots of choices like RS-485 BiSync, RS-484-Modbus, RS232-Modbus, etc.  See attachment. Are you sure how yours is configured?

 

Mark

Hi Mark,

 

yes, that is still a leftover when I was trying to connect via a Moxa NPort serial device server. This is actually the way I want to connect in the end but to be sure that it is not a faulty device server setting, I connect this way (because iTools connects to the COM1 port without problems).

However, when I change the link type to 2=ASCII, the error messages stay the same. When I change to 1=RTU, I get CRC errors:

When I change the crtscts Option to Yes

 

asynSetOption("EMODBUS", -1, "crtscts", "Y")

 

the error messages are again like with the 0=TCP link type.

Hi Michael,

 

  • drvAsynSerialPortConfigure("EMODBUS","COM1",0,0,1)
  • modbusInterposeConfig(EMODBUS, 0, 2000, 0)

 

The above 2 lines do not look internally consistent to me.  The first line says you are using a serial port for communication.  The second line says that the link type (second argument) is 0, which is Modbus TCP.  Normally when you communicate over a serial link type needs to be 1=RTU or 2=ASCII.

 

Mark

Subject: Eurotherm2604 modbus support

 

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):
