The processor base unit provides the electrical connections between the T9110
processor modules, and the rest of the controller modules and has the following
connections:
Command and response bus connections for up to 48 I/O modules
Inter-processor links
Two Ethernet 100 BaseT connectors per processor
Two serial data connections per processor
Dual +24v System power
Ground stud
Program enable key
The processor base unit holds the IP address of each processor module separately in a
BUSP (U1 shown in above illustration) which is installed during manufacture. This
means that you can remove a defective processor module and install a new one
without needing to set up the IP address of the new module.

The external connections for Earthing, Ethernet (E1-1 to E3-2), serial data (S1-1 to
S3-2) and the +24V dc Redundant powers supplies (PWR-1 and PWR-2) are all
located on the T9100 Processor Base Unit. There are two serial data and two
Ethernet connectors for each processor module. two connectors for the dual
redundant power supplies, a stud for the Earth and a connector for the security device
(KEY) also known as the Program Enable Key.
Note: The FLT connector is not used.
