M221 IOScanner - How to handle failed channel with modbus TCP IOScanner on M221?

[joel_mora_soati]

Hello

I'm working on communicating 1 TM221CE40T with 4 ATV930 and other M221 PLC, using modbus TCP IOScanner.

I created the configuration for the 5 channels in the PLC program but 3 of them not connected to the network right now.

I tested the program with the last two left, the result is that the communication get dropped (%SW212 <> 2) and affected the two devices connected in the network. 

Do you have any suggestions to handle in a proper way the IOScanning errors and if this is the expected behavior?

Regards!

You could try if the Network Objects could solve your problem. I did not test it. 

 An other option could be to use the integrated functions blocks read_var write_var instead of the use of the IO Scanner. In that case you could easily activate and deactivate slaves.
