5.2.10.2 CHECK LOGICAL CONNECTIVITY
The logical connectivity depends on the chosen data protocol, but the principles of testing remain the same for all
pr
otocol variants:
1. Ensure that the communications baud rate and parity settings in the application software are set the same
as those on the protocol converter.
2. For Courier models, ensure that you have set the correct RP1 address
3. Check that communications can be established with this IED using the portable PC/Master Station.
5.2.11 TEST SERIAL COMMUNICATION PORT RP2
RP2 is only available on selected models. If applicable, this test is the same as for RP1 only the relevant terminals
ar
e 82 and 84.
5.2.12 TEST ETHERNET COMMUNICATION
For products that employ Ethernet communications, we recommend that testing be limited to a visual check that
the corr
ect ports are fitted and that there is no sign of physical damage.
If there is no board fitted or the board is faulty, a NIC link alarm will be raised (providing this option has been set in
the NIC Link Report cell in the COMMUNICATIONS column).
5.2.13 TEST CURRENT INPUTS
This test verifies that the current measurement inputs are configured correctly.
