3.8 Field monitoring (for LD-MRS400xxx only)
With the aid of integrated field monitoring, the LD-MRS evaluates up to 16 evaluation fields
within its scan range. It signals field violations (events) through a maximum of 10 logical out-
puts. The logical outputs can be assigned via the CAN bus to external, physical ports (that
can each be configured as inputs or outputs) of a maximum of two CAN modules (optional
accessory). A CAN module has 8 I/O ports.
Systems for collision protection, object protection or access monitoring can be created us-
ing field monitoring.
The LD-MRS uses up to 16 evaluation cases to adapt to the evaluated situation. For each
evaluation instance, and, the following are selected: one of 16 configurable evaluation
fields, one evaluation strategy per field, a logical output and in certain circumstances a com-
bination of the logical inputs that activate the evaluation instance. For each logical output,
a link can be selected that determines the result of the output if more than one evaluation
instance affects the output.
In the example in
Fig. 3-30 , evaluation field 1 is used in evaluation instance 1, and evalua-
tion field 2 is used in evaluation instance 2. Both evaluation instances affect logical output
OUT1. If the results of the evaluation instances are AND-linked, the output only switches
when both evaluation instances report results.
