After the hardware part is properly installed, it is possible to test the
communication. Measurements can be carried out using the FCB
program. The OIRX element has an ERR terminal for indicating fatal
errors on the link (1 = error, 0 = no error). The reason for the error is
indicated by the ERRC terminal; the error codes are listed in the AC 80
PC Elements Reference Manual.
