OptoOPCServer Indirect (CONT) method unable to scan groov discrete outputs with On/Off-Time Totalizer features
R10.5a to current
When a groov discrete output configured with the On-Time or Off-Time Totalizer feature is added to an OPC client using the OptoOPCServer CONT scanner, the retrieved values are always empty.
Additionally, if I/O scanning is configured in PAC Display Configurator (Configure > Runtime > I/O Unit Tags) to be done through the control engine (indirect method) instead of scanning the I/O directly (default), retrieved values will also be empty in PAC Display.
Use the OptoOPCServer Direct (MMIO scanner to add digital outputs with features to an OPC client.
For PAC Display, use the default configuration (scan I/O directly) instead of scanning through the control engine.
For more information, review the OptoOPCServer User’s Guide (Form 1439).
