TB807 ModuleBus Terminator Plug
The Terminator plug must always be mounted on the last I/O unit of the
ModuleBus. If no units are used on the ModuleBus, no bus termination is required.
No ModuleBus termination is required in redundant CPU configuration.
TB852 RCU Link Terminator Plug
The RCU Link Terminator Plug is required when the PM861/PM864 processor unit
operates in single configuration.
TK850 CEX-bus Extension Cable
A 0.7m (2.3ft.) extension cable, complete with connector (type DB25P-metal
housing) provides connectivity to Communication Interface units between adjacent
DIN-rails. It is always used in redundant CPU configuration for connecting the
CEX-bus between the two processor units.
TK851 RCU Link Cable
The Redundant Control Unit Link Cable is used to transfer log data from the
Primary CPU to the Backup CPU, and to exchange status and control information
between the Primary and Backup CPUs. The RCU Link uses 68-pole connectors,
one of which is labeled "UPPER". The CPU connected to this connector will be
defined as the upper CPU in the Control Builder and Operator Station.
