Automation Solutions has software that can communicate to many devices, including the IQ Analyzer. We have used it with CH's MPCV relay, IQ 200 meter, and Allen-Bradley Micrologix PLC.
If the metering and data may be used for revenue or revenue-check applications, consider using "conventional" ANSI-C12 components and data formats.
We have a whole series of IQ 200 meters and several IQ 6600 series analysers. Siemens PLCs control our plant. Can automation solutions communicate to profibus controlled devices?
