test it together with the function that operates it. Trig the function and check that the
counter result corresponds to the number of operations.
6.9.2.1 Completing the test
Continue to test another function or end the test by changing the Test mode setting to Off.

purposes.
6.10 Testing metering functions
6.10.1 Pulse counter PCGGIO
The test of the 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 = Enable or Operation =
Disable and the function blocked or unblocked. The pulse counter value is then checked
in PCM600 or on the local HMI.
6.11 Testing station communication
6.11.1 Establishing connection and verifying the IEC 61850
communication
About this chapter
This chapter contains instructions on how to establish connection and verify that the IEC
61850 communication operates as intended, when the IED is connected to an Ethernet
network via the optical ports of the COM module.
6.11.1.1 Overview
The COM03 ports are used for substation bus (IEC 61850-8-1) communication as well as
redundant communication.
The COM05 ports are also used for communication but not redundant communication.
For IEC 61850-8-1 redundant communication according to IEC62439–3 Edition 2, port
LAN_1A and LAN_1B is utilized.
