Notes on programming
Notice
Only the bits 0+2 or 3+5 are relevant for the purposes of evaluation in the process input
image. You can use bits 0+2 or 3+5 to monitor the temperature of a motor, for example.
Bits 0+2 or 3+5 in the process input image does not have a retentive function. Make sure
at parameter assignment that motor start-up is controlled (by means of an
acknowledgment), for example.
Bits 0+2 or 3+5 cannot be set at the same time, but set one after the other.
For safety reasons, always evaluate the diagnostic inputs of the 2AI RTD High Feature
because measurement is not possible when the EM is removed, when the power supply
to the EM has failed, or in the event of a wire break or short-circuit of the measuring lines.
