Problems With driver ModBus

[jeissonsierrac]

Hi Dears;

We are implementing a project with a weather station which one it's monitored by Modbus Driver, but we have a problem of the connection. The weather station is connected to a protocol converter from RS485 to Modbus TCP (ethernet), the log file of the project reports that it connects, and disconnects in time out of 3000 ms. Despite this problem, the weather station brings information in our system. We want to know, why does this happen? and what could be the solution.

i attached a picture of configuration the Protocol converter RS485 to Modbus and the configuration of Driver in Wincc OA, additional a picture the log file of our project.




We appreciate your help.

The information in the log message is that the peer (other side of the communication) has closed the connection. The WinCC OA driver is only reacting on the information that the connection was closed.
Please check if there is information avaiiable at the peer why the connection was closed.
