• Notes on Programming
Attention
Only bit 0/3 is relevant for the evaluation in the process image of the inputs.
•
The temperature of, for example, a motor can be monitored via bit 0/3.
Bit 0/3 in the process image of the inputs does not save data. During
•
configuration note that, for example, a motor makes a controlled start (via an
acknowledgment).
For safety reasons always evaluate the diagnostic entries of the 2AI RTD High
•
Feature, because measuring is not possible when the electronic module is
removed, failure of the power supply or the measuring wires are broken or
short circuited.
