T9100 Processor Base Unit
Processor base unit supports up to three processor modules as a redundant
group. The processor base unit supplies the electrical connections between the
T9110 processor modules, and for the remaining controller modules. Each
base unit can be mounted onto standard DIN rails or directly onto a panel or
wall. The moldings use slots and clamps for DIN rail mountings, and holes for
screw fixing to flat panels.
The processor base unit holds the IP address of each processor module
separately in a BUSP component that is installed during manufacture. This
allows you to remove a faulty processor module and install a new one without
needing to set up the IP address of the replacement module.
