Prepare the IED for verification of settings as outlined in section 1 "Overview" and section 2
"Preparing for test" in this chapter.
There are two types of internal self-supervision of the RTC.
The I/O-circuit board is supervised as an I/O module. For example it generates ‘FAIL’ if the
board is not inserted. I/O-modules not configured are not supervised. When an RTC- module is
configured as a logical I/O module it is also supervised.
There is also communication supervision that generates the output ‘WARNING’ if one of the
RTC-modules signals ‘COMFAIL’. Each RTC-module has an error output (‘COMFAIL’)
which is set to a logical 1 if anything is wrong with the communication through the actual mod-
ule. Status for inputs and outputs as well as self-supervision status are available from the local
HMI.
Test correct functionality by simulating different kind of faults. Also check that sent and re-
ceived data is correctly transmitted and read.
A test connection is shown in figure 36 . A binary input (BI) is connected to an RTC function
input at end1, for example SEND01, and at the other end a binary output (BO) is connected to
the received function output, for example REC01. The binary signal is transferred to the remote
end (end2) through a communication link. Check at the remote end that the corresponding signal
(REC01) has been received. Repeat the test for all the signals used by the RTC function.
