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 è 8.3 LED display.
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
– Bit 0: monitoring of SCS (short-circuit or overload of the sensor supply)
Allocation
– Bit 1 ... 6: reserved
– Bit 7: monitoring of parameterisation errors
– Bit 0, 7:
Values

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
– Bit 0: behaviour after short circuit/overload
Allocation
– Bit 1 ... 7: reserved
– Bit 0:

è Further information.
– 0 = inactive
– 1 = active (default)
– 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).
