S Notes on programming
Important
S
Only bit 0/ 3 is relevant for the purposes of evaluation in the process input
image. You can use bit 0/ 3 to monitor the temperature of a motor, for example.
S
Bit 0/ 3 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.
S
For security 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.
