M340 PLC to read from Allen Bradley 20-COMM-M

[JoeyBlack]

Hi

I need help with communication but M340 PLC and 20-comm-m adapter. I am fairly new with the Schinder PLC and first time with anything from Allen Bradley.

Using the READ_VAR block, I keep getting error 16#07 (Addressing error), Allen Bradley Tech have set-up Datalinks to read from, but I can't get the addressing right as per the adapter manual.

Please, ant assist would be greatly appreciated.

 try get data from AB PLC using a Modbs Scanner software. here it's easy to change everything ie Unit ID if it's requiered in the AB PLC.

There is a lot of scanners, but this one is free and fine:
