The EMC-Test Mode

It is possible to put the Master into a state that is not AS-i compliant. This option can be useful for specific tests on AS-i under laboratory conditions (e. g. tests with bursts on the lines or tests with very long wires).

By putting the AS-i Master into the EMC Test Mode it becomes an AS-i test set-up for experts.

In the test mode, the list of addressed slaves and the telegrams for contacting these slaves are given by the host. Also, it is possible to decide from within the host whether faulty answered telegrams from the AS-i Master may be repeated or not (Note: in regular AS-i operation, data telegrams can be repeated one time). As above, there are two error counters. However, in this mode the first one counts all telegrams while the second counts all faulty telegrams.

The AS-i_EMC.EXE program is designed for the operation of the AS-i Master in the EMC test mode. This program is also delivered as program for Windows.
