Man that sounds like it could be a lot of work, a lot of headache and hassle. I was wondering how exactly the data would be provided to the CompactLogix controller being that the tutorial video I saw just showed INT arrays. Yeesh.
I'm not sure which device Dock is talking about but the Spectrum Controls Gateway is not limited to one data type. It supports all of the data types available in AB PLC's and the four basic MB words (among others) and in fact while you need to be careful in doing this, you can read one data type from one controller and write it to a different controller as a different data type (read a USHORT from a Modbus RTU device and write the data to a CompactLogix as a DINT for example). The only data types you can mix are Strings, a String has to go to/from another String.
Using the Spectrum Controls Gateway is no different with regards to moving data between PLCs (and other devices) except that the Gateway does the work for you, you don't have to do any messaging in the PLCs (other Gateways operate in a similar fashion).
