FBoxes
For the easy use of the temperature module, an FBox called PCD2.W745 is included
in the standard analogue FBox library of Saia PG5
®
.
First of all, this FBox allows configuring the module according to the individual meas -
urement setup. Once the FBox has configured the module, it switches automatically
in data acquisition mode. In addition to the reading of the analogue values from the
W745, the FBox delivers powerful diagnostic information about sensor failures.
For correct working, the FBox should be placed in a cyclic organisation block (COB).
FBox name: A name can optionally be given to the FBox.
When several FBoxes are used, FBox must have an individual name.
