Modbus communication with CXA_ModbusTCP library

[Lauri]

Hello.

Customer has problem with this library when they try to communicate with third party Modbus server. It seems that the modbusLink provided by the Client function block fails after a while of making read commands. And exspecially when using write command. 

They are using latest version of 1.12. I'll start by asking has there been any improvements to this library in newer versions?

Hi Lauri,

could you give a bit more details?
What is the 3rd party device, what errors are on the function block?
Which version of the library are you using?

Regards
