S5-100U Addressing
6.4.2 Digital Input/Output Module, 16 Inputs, 16 Outputs, 24 V DC
for All CPUs Version 8MA02 and Higher and
for CPU 102, Version 8MA01, Revision 5 and Higher
Plug the module only into slots 0 through 7.
This module occupies the same address space as an analog module. However, only the first two of
the eight reserved bytes are used.
The address consists of byte address n or n+1 and channel number Y. “n” is the start address of
a slot, the first of the reserved bytes (e.g., byte 64 for slot 0). “n+1” is therefore the second of the
reserved bytes. The designations “n” and “n+1” are printed on the frontplate of the module.
The input and output information occupies the same addresses.
The channel number is defined by the connection of the actuators and sensors to the crimp
connector. The channel numbers are printed on the frontplate.

Examples: Determining the Address
1) You plugged the module into slot 4 and connected an actuator at byte n,
channel 4. The address is 96.4.
2) Address 113.3 indicates a sensor or an actuator is connected at byte n+1,
channel 3. The module is plugged into slot 6.
6.4.3 Function Modules
Function modules have module-specific addressing. Some function modules are addressed like
digital modules, and other function modules are addressed like analog modules. The addressing for
each function module is explained in chapter 15.
