External switching outputs
A CAN module (part no. 6038825) can be supplied to expand the switching outputs. With
this module additional external switching outputs are made available.
The external switching outputs have the same functionality as the digital switching outputs
on the LMS1xx.

Logical operators for inputs and outputs
With the aid of an evaluation case the inputs and outputs on several LMS1xx can be linked
together (see
section 3.9.1 “Evaluation cases” on page 41
).
Fig. 28:
Logical operators for inputs and outputs
In the example output 1 on the LMS1xx at the bottom is connected to input 1 on the LMS1xx
at the top. An evaluation field infringement is therefore signalled at the input on the LMS1xx
at the top. This LMS1xx links the input to output 1 in its evaluation case 2. At the same time,
evaluation case 1 also acts on the LMS1xx at the top and its output 1. Using the OR operator
for the two results, evaluation field infringements on both LMS1xx are signalled on output
1 on the LMS1xx at the top.
Evaluation case 1:
pixel evaluation
acts on output 1
Evaluation case 1:
pixel evaluation
acts on output 1
Evaluation case 2:
I/O operator
acts on output 1
Output 1:
OR operator
for the evaluation cases 1 and 2
Input 1:
