I have an application with Flexy 205 communicating in Modbus TCP with PM573 ABB controller. I tested successfully a float tag using, for example, address 40097F to read %MW0.97 value on controller.
I tested too a boolean tag using, for example, address 40029#0 to read %MX0.29.0 value on controller, but without success. PM573 controller uses byte structure for boolean tags, for example, %MX0.29.0 … %MX0.29.7, and I understood that Flexy 205 uses Integer (16 bits) values in the minimum size. I tried different ways to read the value, for example, using directly address 29, and without success too.
In the same time, I configured a SMS Alarm for this tag and I received the messages when change the value from 0 to 1, even Flexy 205 doesn´t change the value on “Value” configuration screen (in View mode).
Am I using wrong way to define the address? Is there anything else that I can do?
