5. Analogue output module CPX−2AA−U−I
Module parameters: Output analogue−value data format
4828 + m * 64 + 3
Function no.
Description Determines the format in which the digital output words from the output module
are interpreted for the analogue output signals.
Bit Bit 0...3:
Bit 4, 5:
Bit 6, 7:
Values Bit 5
0
0
1
1
Remark The reserved bits 0...3 and 6, 7 must always be 0. If one or several bits are set to
1" during parametrizing, the parametrizing carried out is invalid and therefore
not effective. If the module parameter Monitoring parametrizing faults" is set to
active", the relevant fault will be displayed.
Further information on this parameter can be found in section 5.4.4.
