Most Honeywell DCS Systems support either Serial Modbus or Modbus TCP communication. If your application involves Rockwell Automation PACs or PLCs than consider one of our In-Chassis modules such as the MVI56E-MCM or the MVI56E-MNET. If the application is using another PLC or PAC than a gateway solution is more practical. Please use the gateway product selector to find the best solution, or call your Regional Technical Support Center.
