FAQ

Frequently Asked Questions

Can the PLC controller be integrated with my existing plant SCADA system?

Yes. The controller supports Modbus TCP, Profinet, and Ethernet/IP. Most SCADA systems can communicate with at least one of these protocols. We provide the register map and interface documentation.

What alarm conditions does the controller monitor?

The controller tracks: low/high purity, high dew point, high pressure, low flow, valve cycle count, filter replacement due, and sieve bed end-of-life prediction.
