Can someone please confirm how Generic Ethernet Module 'Configuration Instance' data in an AB Logix processor is used?
More specifically...I have a device with only an 'Input Data - DINT' instance and numerous bytes of Configuration data (no output data). When I create the module the associated tags are automatically generated in the controller tag data base as usual (example tags: Device:I & Device:C) . The input data is implicitly (I/O connection) messaged into the associated PAC tag from the device based on the RPI rate. I believe the Configuration data is only written to the device when an explicit message is activated from PLC code...so unless a Message instruction is activated from code no data with ever be written to the device?
Is this correct?
Thanks
