4.6.3
Enabling Local Override
Parameter for enabling/disabling the module key Up/Down for the 'Local override'
function.
The general switching behavior (for enabled local overriding) is defined as follows:
Switch from automatic to local override (manual):
The current process value is valid until a new manual command is issued.
Switch from local override to automatic:
The automatic process value becomes valid once the Profinet I/O controller
writes a new value.

4.6.4
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:

Inactive 1 Inactive
4.6.5
Process Data
The allocation of process data of binary output-configured channels is described in
'Process Data Channel Mapping' for the corresponding TX-I/O module.
If the TX-I/O BIM has the status 'Masterdown', the relay (after a delay for an active
pulse) will return to its original status (i.e., no new output pulse is generated).
If local override is active after starting the TX-I/O, no output pulse is generated
either.
