process Status change occurred without control action (for example external trip of a
circuit breaker or failure inside the breaker)
origin.orIdent
 This is the address of the originator. The value the user wants depends upon
the role of the PLC.
ctlNum
 This is of no consequence to the IED and only appears in reports. This is an
optional parameter. The ctlNum may be of interest to the user when the
Client uses the same control number for a complete control sequence:
select, operate, …
T
 This is the time the IEC-61850 Client sent the control request. The IEC-61850
Client driver writes this value using the current gateway time.
(This table has been taken directly from the IEC 61850 Standard document)
Test
 Test issues are still early in IEC-61850 use. This is only required if the
customer really wants to issue a control command which should be
interpreted by the IED as a command that should not cause a real operation.
Check

The user’s specific application determines if or how this parameter will be
used. This parameter determines whether control actions are done
immediately without interlock or synchrocheck, or if an interlock or
synchrocheck will be done before the operation is done. Some other part of
the user’s application may do these checks anyway, even if checks are not
used here. The PLC can be set to always use or always not use checks, or it
can enable or disable checks for each control action when the control
message is sent.
