3.8 Field application
With the aid of the integrated field application, the LMS evaluates up to 10 evaluation fields
within its scan area. Using the field application, you can e.g. implement systems for collision
protection, for building surveillance or for access monitoring.
Fig. 18: Principle of the field application
The LMS is adapted to the evaluation situation with the aid of up to ten evaluation cases. In
the evaluation case, one of ten configurable evaluation fields, an evaluation strategy, an
output and in somecircumstances a combination of inputs that activate the evaluation
case, are selected. An operator is selected for each output; this operator determines the
result on the output if more than one evaluation case acts on the output.
In the example in
Fig. 18 , in evaluation case 1 evaluation field 1 is used, in evaluation
case 2 evaluation field 2 is used. Both evaluation cases act on the output OUT1. If an AND
operator is used for the results of the evaluation cases, then the output will only switch if
both evaluation cases are signalling an event.
