Configuring the CAN module
Setting the CAN address
For addressing in the CAN bus, the address range 1 to 127 is available. By default, the ad-
dress of theLD-MRS is 1. Each address assigned to a device may only occur once (such as
10, 11, 12).
Important
Switch 8 must always be in the 0 position (OFF).
The switches may never all be in the 0 position (OFF) at the same time.
In this configuration, the CAN module will not start.
