floor standing configuration.
VMEbus modules The chassis has ten VMEbus slots that support a variety of MTS
VMEbus plug-in modules.
• The chassis requires at least one processor module. The processor
module provides the processing power to manage the other plug-
in modules that make up the controller.
• The chassis can have up to eight I/O Carrier modules. Each I/O
Carrier module supports up to four mezzanine cards.
• An optional Global Resource (GRES) module provides several
connections to communicate with external devices such as a
remote station control module, temperature controller, and other
devices.
Transition bus Transition modules are panels plugged into the transition bus located
in the rear of the chassis. Each transition module allows external
devices to interface with the chassis. Transition modules provide the
following:
• Hydraulic control connections
• Station control connections
• Analog input and output connections
• Digital input and output connections
