OPC Enhancements for AX-S4 MMS


The latest release of AX-S4 MMS (V4.30) has added important new features to the OPC interface:

  • Support for receiving MMS InformationReports from remote devices.
  • Support for controlling and receiving UCA Reports from UCA devices.

These new features provide higher system performance by eliminating the need to poll for data. Instead, devices can report the data to AX-S4 MMS on a report by exception basis. Reporting by exception significantly improves overall system performance, network bandwidth consumption, and CPU utilization.

AX-S4 MMS is a MMS/UCA interface for applications like InTouch, Fix, Cimplicity, Excel, as well as any other OPC or DDE program and is being used successfully in a variety of industries across many different kinds of applications including:

  • Substation SCADA involving PLCs, meters, and protection relays
  • Supervisory control of machine tools utilizing MMS based CNC
  • Test systems for testing/verifying functional characteristics of MMS/UCA devices
  • Operator interface for PC based controls
