Issue:
Does the Unity Momentum PLCs support a Modbus Function Code 22 (16 Hex) Mask Write 4X Register request?

Product Line:
Momentum

Environment:
EcoStruxure Control Expert
Unity Pro

Resolution:
Yes. The New Unity Momentum processor does support Function Code 22 (Mask Write 4X Register). This Modbus/TCP messaging command is supported only with the Momentum acting as a Server and responding to a Function Code 22 request from any 3rd party controller or a SCADA.
