Notes on programming
● Bits 0+2 are relevant for evaluation in the process image input. You can monitor, for
exampl
e, the temperature of a motor using bits 0+2.
● Bits 0+2 in the process image input cannot be saved. During parameter assignment, take
into consideration that a motor, for example, starts up in a controlled manner (via an
acknowledgment).
● Bits 0+2 can never be set at the same time; they are set one after the other.
NOTICE
No measurement is possible in the following cases:
• When I/O modules are pulled out
• When s
upply voltage to the I/O module fails
• When there is a wire break or short-circuit in the measuring lines
Therefore, always evaluate the diagnostics entries of the AI 4×RTD/TC 2-/3-/4-wire HF for
safety reasons.
