Replacing a TX-I/O Plug-in Module
NOTE:
If reusing an I/O module, reset the module to factory settings before you begin.
The plug-in module of a TX-I/O module assembly can be replaced at any time by the
same or a compatible I/O module type, even while the system is running.
1. Swivel the address key outward to switch off the load to the I/O module.
 Leave the base of the key plugged into the terminal base.
2. Remove the plug-in module from its terminal base.
3. Insert the new plug-in module.
4. Swivel the address key back into position.
 As soon as the new module starts communicating with the PXC Modular, PXC-36,
or P1 BIM, it is configured according to the module address and starts operation
shortly afterward.
Replacing a TX-I/O Module Assembly

module assembly catches on the bus connector.
