IEC850 driver does not behave according to the latest version of the standard - client must actively reserve the BRCB even if ResvTms is -1

Description

The IEC850 driver omits the reservation of BRCB, if the BRCB instance is already pre-reserved (when attribute ResvTms is -1). But the driver should reserve it (write BRCB.ResvTms > 0) also in this case.

Background information: According to IEC61850-7-2 amd1 Ed.2 (called Edition 2.1) it became mandatory for a client to reserve the BRCB actively. This applies even if the BRCB instance is already pre-reserved for this client via the SCL file. The client must write a value > 0 for ResvTms before configuring and activating the BRCB if the ResvTms attribute is present in the BRCB.

Solution: The behavior of the driver has been adjusted the the updated statement in the standard. 

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 10 or higher.
