WG10 Future Work #6578
Extension of the AddCause required to reflect communication issues in multi level control
IEC 61850-7-2; IEC 61850-8-1, 80-6
During the review of the control model of the Proxy/Gateway in IEC 61850-80-6 we found that the existing enumeration for the AddCause does not include values to reflect the situation where the Proxy/Gateway issues a negative confirmation to the control center client when the communication with the underlying IED that executes the command is disturbed, or the connection to the device is lost.
This issue is not only relevant for the communication to the control center, but on always when the control action involves more than one communication level, e.g. Substation Scada to Breaker IED via an bay controller IED.
Attached is a slide set which explains the need and proposes the new enumerated values for the AddCause.
TF IEC 61850-80-6 proposed to extend the enumeration for the AddCause with 2 new ACSI values
