TX-I/O Modules
Swiveling the Address Key Out
When the address key is swiveled out, the I/O module is inactive, and it cannot be
overridden locally. The state (automatic operation, tool override, or local override),
configuration, and parameters of the individual I/O points are saved in the non-volatile
memory of the plug-in module.
Swiveling the Address Key Back into Place
When a fault is repaired or an address key is swiveled back into place, operation
resumes in the same state as before (automatic operation, tool override, or local
override). The process values are only stored in tool override or local override.

To Park a Module
In the "parked" position the plug-in modules are fully isolated from the terminal bases.
The connected field devices can be measured through the test pickups without being
affected by the plug-in module electronics.
1.
Squeeze module sides above the disengage catch and pull up slightly to disengage
the I/O module from the terminal base.
2.
The I/O module is retained in the terminal base (‘parked’), but all wiring
