The Veris H8920-3 Auto Propagate Feature is not configured to automatically update all network variables. The Auto Propagate Feature of the H8920-3 must be set accordingly for its network variables to be automatically updated to the UNC.
The following steps configure the H8920-3 Integrator to automatically update it variables to the UNC.
- Open the UNC-xxx station in WorkPlace Pro.
- Expand the folder containing the H8920-3 shadow object
- Right-click and open the H8920-3 properties
- Click on the OpenLoopSensor tab and then Config tab
- Set the nciMaxSendTg to and value above its default of “0”. (suggested value is 100)
The Veris H8920-3 Integrator will now periodically update its network variables to the UNC.
NOTE: The following is an excerpt from the Veris H8920-x Installation Guide:
The H8920-x automatically propagates all network variables. If nciMaxSendTg is set above zero (default is zero), all variables are propagated periodically. Units are in tenths of a second. For example, if nciMaxSendTg is set to 100, the H8920-1 will automatically propagate all variables every 10 seconds.
