Mechanical Coding of Connector Boards
I/O module and connector boards are mechanically coded to prevent them from being equipped
with improper I/O modules. Coding avoids installation of improper I/O modules thus preventing
negative effects on redundant modules and field zone. A part from that, improper equipment
has no effect on the HIMax system since only I/O modules that are correctly configured in
SILworX enter the RUN state.
I/O modules and the corresponding connector boards have a mechanical coding in form of
wedges. The coding wedges in the female connector of the connector board match with the
male connector recesses of the I/O module plug, see Figure 5.
Coded I/O modules can only be plugged in to the corresponding connector boards.
