13.13.1.5 Completing the test
Continue to test another function or end the test by changing the Test mode setting
to Off. Restore connections and settings to their original values, if they were
changed for testing purposes.

13.14.1 Event counter CNTGGIO
The event counter function CNTGGIO can be tested by connecting a binary input
to the counter under test and from outside apply pulses to the counter. The speed of
pulses must not exceed 10 per second. Normally the counter will be tested in
connection with tests on the function that the counter is connected to, such as trip
logic. When configured, test it together with the function that operates it. Trig the
function and check that the counter result is the same the number of operations.
13.14.2 Event function EVENT
Prepare the IED for verification of settings as outlined in section
"Overview" and
section "Preparing for test" in this chapter.
During testing, the IED can be set when in test mode from PST. The functionality
of the event reporting during test mode is set in the Parameter Setting tool in PCM600.
• Use event masks
• Report no events
• Report all events
In test mode, individual event blocks can be blocked from PCM600.
Individually, event blocks can also be blocked from the local HMI under
Main menu/Test/Function test modes/Monitoring/EventCounter(GGIO)/CNTx

13.15.1 Pulse counter PCGGIO
The test of Pulse counter function (PCGGIO) requires the Parameter Setting tool in
PCM600 or an appropriate connection to the local HMI with the necessary
functionality. A known number of pulses with different frequencies are connected
to the pulse counter input. The test should be performed with settings Operation =
On or Operation = Off and the function blocked or unblocked. The pulse counter
value is then checked in PCM600 or on the local HMI.
