OptoOPCServer Indirect (CONT) method unable to scan groov discrete outputs with On/Off-Time Totalizer features


Applies To:

OptoOPCServer

Versions Affected:

R10.5a to current


Symptoms:

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.

Workaround:

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).
