In looking over the Modbus structure for various packets it looks like this must all be assembled in the PLC code and sent out in a message and then received and decoded. And then there is error handling and making it robust. It looks like a weeks worth of work plus testing time to get this to work for a multidrop array of flowmeters.
To get to the point, does anyone have ideas of where to get or even view some sample PLC code (AB Micrologix1400 or any SLC/RSLogix500 based PLC) that talks Modbus to a Micromotion flowmeter? PLC code to communicate with an MVD direct connect standard flowmeter would be best but I think any Micromotion flow meter would get me what I need to customize the PLC code.
