7. Pressure sensor module CPX-4AE-P
Module parameter: Lower limit values / Upper limit values
Function no. Lower limit value:
channel 0: 4828 + m * 64 + 12 (Low Byte)
channel 0: 4828 + m * 64 + 13 (High Byte)
channel 1: 4828 + m * 64 + 14 (Low Byte)
channel 1: 4828 + m * 64 + 15 (High Byte)
channel 2: 4828 + m * 64 + 16 (Low Byte)
channel 2: 4828 + m * 64 + 17 (High Byte)
channel 3: 4828 + m * 64 + 18 (Low Byte)
channel 3: 4828 + m * 64 + 19 (High Byte)
Upper limit value:
channel 0: 4828 + m * 64 + 20 (Low Byte)
channel 0: 4828 + m * 64 + 21 (High Byte)
channel 1: 4828 + m * 64 + 22 (Low Byte)
channel 1: 4828 + m * 64 + 23 (High Byte)
channel 2: 4828 + m * 64 + 24 (Low Byte)
channel 2: 4828 + m * 64 + 25 (High Byte)
channel 3: 4828 + m * 64 + 26 (Low Byte)
channel 3: 4828 + m * 64 + 27 (High Byte)
Description The lower and upper limit values for the pressure diagnostics notifications are
specified separately for each channel with these parameters. Undershooting or
overshooting of limit values is only signaled if pressure diagnosis is activated via the
the limit value monitoring parameter for the corresponding channel (see Tab. 7/9)
and no parameterisation error exists.
Bit Bit 0 ... 7: High Byte or Low Byte of the limit values
Values Defaults for each channel CPX-4AE-P-D10:
– lower limit values
– upper limit values
Defaults for each channel CPX-4AE-P-B2:
– lower limit values
– upper limit values
Note The limit values are not checked for validity during parameterisation! Unsuitable
parameterisations are adopted – in this case, the module can react unexpectedly.
Check the parameterisation!
If the "Monitoring of parameterisation errors" module parameter is active, then a
corresponding error is signaled. Tab. 7/3 shows the possible parameterisation
errors.
