Variable Slot Address Assignments
The S5-115U offers you the possibility of assigning an address to each slot. You can do this if an
IM 306 interface module is plugged into the central controller and each expansion unit. For
addressing purposes, it does not matter whether the module in question is plugged into a central
controller or an expansion unit. Under a hinged cover on the right side of the interface module is
an addressing panel. It has a DIP switch for each slot. Use the DIP switch to set the least significant
byte number for a particular slot.
Note
Input and output modules in different slots can have the same address.
