Module Parameter Input Analogue−Value Data Format - Festo CPX-AB Series Electronic Manual

3. Analogue input module CPX−4AE−I
Module parameters: Behaviour after short circuit/overload
Function no. 4828 + m * 64 + 1
Description Determines after a short circuit in the sensor supply whether the power is to
remain switched off or whether it is to be switched on again automatically.
Bit Bit 0:
Values 0 =
1 =
Bit 2...7: reserved
Remark With the setting Leave voltage switched off", Power off/on is necessary for
switching the power on again. Ascertain the setting which is necessary for
reliable operation of your machine or system. Further information can be found in
section 3.5.1.
Tab. 3/11: Behaviour after short circuit/overload
Module parameters: Input analogue−value data format
Function no. 4828 + m * 64 + 3
Description Determines the format in which the analogue input signals are provided by the
CPX terminal.
Bit Bit 0, 1:
Bit 2...7: reserved (= 0)
Values Bit 1
0
0
1
1
Remark The reserved bits 2...7 must always be 0. If one or several bits are set to 1" dur
ing parametrizing, the parametrizing carried out is invalid and therefore not effec
tive. 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 3.4.4.
