TX-I/O PROFINET BIM V1.0
CM110564en_02
Building Technologies
Parameters
23.09.2010
Switch from local override to automatic:
The automatic process value becomes valid once the Profinet I/O controller
writes a new value.

4.9.6
Local Override Mode
Parameter for defining the type of 'local override' signal.
A logical '1' is usually interpreted as 'active'. However, it is possible for migrations
to interpret a logical '0' as 'active'.
The following assignments apply here:
Value
Input
Local override
Active 1
Active
Inactive 0 Active
Active 0
Inactive
Inactive 1 Inactive
4.9.7
Process Data
The allocation of process data and the channel status information of multistate
output-configured channels for local override are described in 'Process Data
Channel Mapping' for the corresponding TX-I/O module.
[MOValue] represents the current status. During the 'off' pulse, [MOValue] changes
to '0'. During the delay period [MinOffTime] the current [MOValue] differs from the
commanded value.
If [MOValue] is invalid (i.e., no corresponding channel is available), then
a quality error message (Reliability) is generated:
[Quality = MULTISTATE_FAULT]
a backup value becomes valid according to the value in [BackupMode].
4.9.8
Channel Diagnosis
Alarm type
Cause / solution
Invalid
Check the module configuration and parameterization
No_Output
Operating voltage too low -> check the power
Multistate_Fault
Mapping error -> check the multistate functions
If the TX-I/O BIM has the status 'Masterdown'
after a start
, no new output pulses
are generated, regardless of the value [BackupMode].
If local override is active after starting the TX-I/O, an output pulse defined by
[MOValue] will be generated.
