Input Circuit Functions
Input expansion – function 9
Function 9 assigns the inputs of the function group to the respective other group and takes
on their input circuit function. Thus with one input module you can expand function block
A or B in the base module by 8 single-channel or 4 dual-channel sensors with the same
input circuit function (e.g. 8x emergency stop or 4x NC/NO electromagnetic switch.
Function 9 must only be selected for one of the two function groups. Otherwise a device
error will be detected and the FLT LED will flash.
Settings: Input module INPUT A Function 9 (input expansion)
INPUT B Function 3 (dual-channel with cross-circuit
monitoring and simultaneity monitoring)
Base module FUNCTION 6
Result: Function 6B on the base module is expanded by the 4 dual-channel inputs
on the input module
With switch positions 0 to 6 there is an AND link in the base module; for switch positions
7 (OR) and 8 (BYPASS) there is an OR link.
For the effects of input module function groups
A and B on the associated base module see page 36.

Example for the interaction of base and input modules
Expansion
function
Input modules act only on the next base
module to the left, with which they form a
coded system group. The blue digits
designate the set functions.
System 1: INPUT A and INPUT B of the
input module act together with base module
function group AB on the four outputs
(green).
System 2: INPUT A of the input module
acts together with base module function
group A on output group A (blue); INPUT B
acts together with function group B on
