Limit counter L4UFCNT
The Limit counter function L4UFCNT can be tested by connecting a binary input to
the counter and applying pulses to the counter. The speed of the pulses must not
exceed the cycle time of the function. Normally the counter will be tested when testing
the function that the counter is connected to, such as the trip function. When the
function is configured, test it together with the function that operates it. Trig the
function and check that the counter result corresponds to the number of operations.
6.11.2.1
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.

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
=
On
or
Operation
=
Off
and the function blocked or unblocked. The pulse counter value is
then checked in PCM600 or on the local HMI.

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.
6.13.1.1
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.
