Module parameters: monitoring of short circuit/overload, monitoring of parameterisation errors
Description
Monitoring of the analogue module for the following errors:
–
Short circuit or overload
–
Parameterisation errors at lower and upper critical limit, hysteresis
The monitoring of the errors can be individually activated or deactivated.
Active monitoring has the following effect:
–
Error message at the CPX bus nodes
–
The error LED lights
SCS monitoring
The SCS monitoring can be activated for the entire CPX terminal
è
Description of CPX system.
Monitoring of parameterisation errors
Prerequisites for the monitoring of channel-specific parameterisation:
–
The “Monitoring of parameterisation errors” module parameter is active.
–
The “Monitoring of parameterisation errors” channel parameter is active
Allocation
–
Bit 0: monitoring of SCS (short-circuit or overload of the sensor supply)
–
Bit 1 … 6: reserved
–
Bit 7: monitoring of parameterisation errors
Values
–
Bit 0, 7:
–
0 = inactive
–
1 = active (default)

parameter
Module parameter: Behaviour after short circuit/overload
Function number
4828 + m* 64 + 1
m = module number (0 … 47)
Description
Determination of the behaviour of the power supply after short circuit or over-
load in an input or output
Allocation
–
Bit 0: behaviour after short circuit/overload
–
Bit 1 … 7: reserved
Values
–
Bit 0:
–
0 = leave voltage deactivated
For voltage recovery, “Power On” or a re-parameterisation of the module
parameter is required.
–
1 = restart voltage
The voltage is restarted automatically after the cause of the error is rem-
edied (default).
