The Model B controller (6000 Series) is the first MOD 300 controller, introduced in 1984. Up to 12 controller modules can be supported by a single Controller subsystem. The controlller module performs the primary functions of data acquisition and control, including I/O processing, continuous control, interlocks. sequential control and communications.
For applications requiring controller redundancy two options are available: Subsystem redundancy, referred to as 11 to 1, where one controller can back up a single subsystem or card file redundancy, 3 to 1, where one controller backs up a single card file of the three possible card files in a subsystem.
Control processing is Configurable Control Functions (CCF) and Taylor Control Language (TCL).
The only I/O option is Direct I/O with 16 analog inputs, 8 analog outputs and up to 48 digital ins or outs, channel selectable. The controller board and the I/O board are physically attached as a complete assembly.
The Bulk I/O subsystem consists of various I/O modules inserted in a Multibus card file. The associated termination panels connect to these I/O modules via ribbon cables.
