3.6 Connector Boards
A connector board connects the module to the field zone. Module and connector board
form together a functional unit. Insert the connector board into the appropriate slot prior to
mounting the module.
The following connector boards are available for the module:

3.6.1 Mechanical Coding of Connector Boards
I/O modules and connector boards are mechanically coded starting from hardware revision
AS10 to prevent them from being equipped with improper I/O modules. Coding avoids
incorrect 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.
