On both left terminals the circuit input (evaluation) is connected, both the
middle terminals are used for connection terminals and the termination
resistor is integrated into both of the right terminals.
The number of the circuit is on the left beside the DIP switch followed by the
number of the circuit on the right beside the XIB terminal block.
Example:
The detector circuit module is registered on the panel.
The panel occupies
circuits 1-10; on the circuit module circuit 11 is located on the right beside
the XIB terminal block, and circuit 12 on the left beside the DIP switch.

10.4 Addressing
The circuit module is addressed via a DIP switch.
A maximum of up to 24 circuit modules L240/MG2 can be managed by the
panel.
The Detector Circuit Modules L240/MG2 and L840/MG4 have a
common addressing range on the XIB bus from 1 to 24. Numbering of the
circuit is undertaken consecutively to the addresses of the circuit module.
Before teaching-in bus motion detectors, all Detector Circuit Modules
L240/MG2 and L840/MG4 must be logged on!
Note:
Cable entry for both circuits is on the
same side. The circuit input is on the
left, the termination resistor on the
right.
