Logical operators for inputs and outputs
With the aid of an evaluation case the inputs and outputs on several LMS can be linked
together (see
section 3.8.1 “Evaluation cases” on page 31
).
Fig. 21:
Logical operators for inputs and outputs
In the example output 1 on the LMS at the bottom is connected to input 1 on the LMS at the
top. An evaluation field infringement is therefore signalled at the input on the LMS at the
top. This LMS links the input to output 1 in its evaluation case 2. At the same time,
evaluation case 1 also acts on the LMS at the top and its output 1. Using the OR operator
for the two results, evaluation field infringements on both LMS are signalled on output 1 on
the LMS at the top.

Data interfaces
The LMS has different data interfaces for the configuration and the transmission of
measured values.
Important
•
It is only possible to output all measured values of a scan in real-time using the Ethernet
interface.
•
The data transmission rate of the RS
F
232/RS-422 interfaces is limited. Therefore these
interfaces are not suitable for transmitting scan data in real time.
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:
active low
Output 1:
active low
