6.5 FLXIO port
The POSYC 3401/3402, are equipped with three FLXIO doors; the ports are isolated in the model 3401 unlike
the model 3402. This proprietary field bus is based on an RS485 electrical interface and allows a reliable real-
time control of complex applications.
The connections are made via the RJ45 connectors; the following illustration shows the pinout of one of the
connectors and the behavior of the LED (S).
This fieldbus requires a minimum CAT 5 type shielded cable, headed with RJ45 connectors.
Refer to the FLXIO and FLXMOD integration manual (DK400076) for using these buses.
