• 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.
