Module parameters: general diagnostics Operator unit
Function no. 4828 + m * 64 + 6 m = module number (0 ... 47)
Description This parameter influences the general diagnostic behaviour of the module.
It determines whether channel-, module- or protocol-specific error messages
should be suppressed or reported.
Active diagnostics cause the following. The corresponding error is:
– sent to the CPX bus node
– displayed using the module error LED.
Observe the exceptions named under the note.
Bit General diagnostics
Bit 0:
output channel 0
Bit 1: output channel 1
Bit 2: output channel 2
Bit 3: reserved
Bit 4: module
Bit 5: failsafe protocol
Bit 6, 7: reserved
[General diagnosis]
[Channel 0]
[Channel 1]
[Channel 2]
[Module]
[Failsafe protocol]
Values 0 = inactive – suppress error message
1 = active – report error (presetting) [Inactive]
[Active]
Note Exceptions:
– Error messages regarding wire break can
not be influenced with this paramet-
er. But the wire break monitoring function can be activated or deactivated with
the monitoring wire break parameter (
Tab. 3/7).
– With module-specific error messages, diagnostic messages from the failsafe
protocol are not suppressed.
Tab. 3/6: General diagnostics
Module parameter: Monitoring wire break Operator unit
Function no. 4828 + m * 64 + 7 m = module number (0 ... 47)
Description Establishes whether the respective output channel should be monitored for wire
break.
Deactivating the wire break monitoring is necessary if:
– a load smaller than the minimum-specified load is to be switched or
– the electrical signal is guided additionally through external relays that them-
selves disconnect the circuit.
