Modbus and MikroTik

Sun Nov 22, 2020 3:56 pm

Hi,

I have mAP Lite connected to Ethernet device on ether1 and to PC on wlan1. The communication PC- Ethernet device is possible only by using Modbus protocol (driver) of OPC server, installed on the same PC.
I have faced two issues:
1. Every 12 seconds approximately the connection is interrupted, and then in a second, is restored.
2. Only system parameters are read by the OPC server (for example, Hostname, Port, IP address, etc.), but not holding registers.
Any ideas how these problems can be solved?

No reason to think your OPC server or even your plc could be the problem based on the description.

First verify logs on mAP lite ... could be that wireless disconnects PC due to some reason (there are many possible reasons, log might give a clue).
