11.10.4 Single command, 16 inputs SINGLECMD
For the single command function block, it is necessary to configure the output signal to corresponding
binary output of the IED. The operation of the single command function (SINGLECMD) is then checked
from the local HMI by applying the commands with Mode = Off, Steady or Pulse, and by observing the
logic statuses of the corresponding binary output. Command control functions included in the operation of
different built-in functions must be tested at the same time as their corresponding functions.
11.10.5 Interlocking
Prepare the IED for verification of settings as outlined in section
for test" in this chapter.
Values of the logical signals are available on the local HMI under Main menu /Tests /Function status /
Control /Apparatus control /Interlocking . The Signal Monitoring in PCM600 shows the same signals
that are available on the local HMI.
The interlocking function consists of a bay-level part and a station-level part. The interlocking is delivery
specific and is realized by bay-to-bay communication over the station bus. For that reason, test the
function in a system, that is, either in a complete delivery system as an acceptance test (FAT/SAT) or as
parts of that system.
11.11 Scheme communication
11.11.1 Scheme communication logic for distance or overcurrent
protection ZCPSCH (85)
Prepare the IED for verification of settings as outlined in section
for test" in this chapter.
Check the scheme logic during the secondary injection test of the impedance or overcurrent protection
functions.
Activation of the different zones verifies that the CS signal is issued from the intended zones. The CS
signal from the independent tripping zone must have a tSendMin minimum time.

2.2.4 The command response for the command to move to the current is changed by
selecting the parameter PosDependent. This action decides if it is allowed. The
response if allowed is now successful.
2.2.5 SXCBR & SXSWI: Execution outputs follow the operation request inputs. If not
blocked, output is maintained active until operation request input is deactivated.
Changes are valid for all 2.2 releases.
2.2.6 -
2.2.6 Support for Direct Operate with enhanced security.
Possibility to use different reservation logic depending on command direction.
