4. Analogue input module CPX-4AE-I
4-16
Sequence for first or startup parameterisation (CPX terminal
in delivery status, monitoring of parameterisation errors
active):
1. First set the desired data format (parameter "Input
analogue-value data format").
2. Then set the upper and lower limits for both channels:
– If the new upper limit value is positive, set first the
upper limit; then the lower limit.
– If the new upper limit is negative (only in the case of
data format "VZ + 15 bits linear scaled"), set first the
lower limit, then the upper limit.
Sequence for modifying parameterisation:
1. Activate, if applicable, the monitoring of parameterisation
errors (module parameter "Monitoring CPX module –
monitoring parameterisation errors" and channel-specific
module parameter "Monitoring channel x – monitoring
parameterisation errors").
2. Set the lower limit to 0 and the upper limit to 4095 for
both channels.
3. Then set the desired data format (parameter "Input
analogue-value data format").
4. If required, then set the upper and lower limits for both
channels:
– If the new upper limit value is positive, set first the
upper limit; then the lower limit.
– If the new upper limit is negative (only in the case of
data format "VZ + 15 bits linear scaled"), set first the
lower limit, then the upper limit.
