In the following example
single-wide axis modules and one IDM system. A sercos node address is not
assigned to the slot-filler or the IPIM module. However, the system identifies
both modules with slot locations.
Node addresses 02 and 05 are available for any of the IDM units, but to avoid
confusion, the node addressing for the IDM units was started at 20. Unlike axis
modules, each IDM unit has switches that determine its node address. In example
1, the IDM unit node addressing is sequential, but it doesn't have to be.

Creating a duplicate node address between the axis modules mounted on the
power rail and the IDM system generates error code E50. Each node address on
the sercos ring must be unique within the range of 01...99.
Slot-filler modules must be used to fill any unoccupied slot on the power rail.
However, you can replace slot-filler modules with AM modules or the 2094-
BSP2 shunt module (maximum one 2094-BSP2 shunt module per power rail).
