The SAI distributor Active Universal is equipped with
the functions of a decentralised I/O system. Each
distributor is equipped with module-specific actua-
tor/sensor functions and a sub-bus interface. The
modules combine the complete electronics in a wa-
ter- and dust-proof protected housing. This enables
their use in harsh environments. The module SAU-
AU M12 SB 2CNT is designed to connect two digital
signals for counting purpose with four M12 connec-
tors.

HINWEIS
After a fallout, mistake or restart, the
ouptput bytes must be reset over the
software. The counter clearance of the
gateways is to be made with the corre-
sponding bits in the counter channel
(chapter 6.6.9). If the output data be
changed, the bit 7 in the counter chan-
nel needs to be changed from 1 into 0.
