Modbus Implementation with Java

[joanna]

I am looking for feedback on various Modbus implementation in Java. Can anyone share their experience with FieldTalk Modbus library, jamod, modbus4j, and modbuspal? What are the pros and cons with each library? Is there any other third party library I can look into?

Just wanted to bump this thread. I'm especially interested in Jamod, but I get the impression that the development effort is no longer active.

Try control.com whose sister site is the Modbus site.

A Modbus programming question/issue is more likely to get a response there, than here, which is primarily Modbus field implementation of devices already programmed as either a master or slave.

Thanks, much appreciated!

jamod works fine for me. I think I found the API for modbus4j to be a bit confusing, but I made the choice to use jamod over a year ago.

I have used modbus4j indirectly through the web based scada mango http://mango.serotoninsoftware.com and it worked well there

Thanks, glad to hear jamod is working for you. Mine is a "hobby" application, so cost is paramount - and it's hard to beat jamod for that!

But alas, my Modbus TCP/RTU bridge has ceased working, so testing must be suspended until a replacement arrives or tech support can tell me how to reset/reload/reflash it.
