Multiple PLC configuration issue

[maoyi8212]

I am trying to configure several different PLC information in a modbus driver, and my configuration is like:
_Mod_Plc_1: PLC number-->1; Transaction timeout-->1000; Frame coding--> TCP; unit address: 0; List of Hosts: 192.168.1.31:5000
_Mod_Plc_2: PLC number-->2; Transaction timeout-->1000; Frame coding--> TCP; unit address: 0; List of Hosts: 192.168.1.31:5001
_Mod_Plc_3: PLC number-->3; Transaction timeout-->1000; Frame coding--> TCP; unit address: 0; List of Hosts: 192.168.1.31:5002
_Mod_Plc_4: PLC number-->4; Transaction timeout-->1000; Frame coding--> TCP; unit address: 0; List of Hosts: 192.168.1.31:5003
_Mod_Plc_5: PLC number-->5; Transaction timeout-->1000; Frame coding--> TCP; unit address: 0; List of Hosts: 192.168.1.31:5004

But when I start up the modbus driver -num 1, there seems some error shows in the log viewer:

Code: Select all

And also for my configured data point, I can only receive the data from 192.168.1.31:5000 and 192.168.1.31:5001. So are there anything wrong about my configuration? Many thanks!

It looks like you have activated the opc client address configs on the '_mp_PUMP2' datapoint. Disable them to avoid the transformation errors.

There seems to be something error in the config of address 'M.3.3.0', which prevents this address from being polled. Check this address config.
Also check the (transformation type of) address config 'M.1.3.0'. Perhaps it has not been configured properly, causing the 'Value out of range' error.

In the posted log part and configuration I do not see any other errors. Perhaps you do not receive data from the other addresses because your device does not accept more connections.

Hi Gertjan, Thank you for your suggestion.

The problem has resolved. The issue occured because I configured the same address for 2 different data point with different configured polling rate. So the configured polling rate is not activated.
