at locations remote from the DSD drive. The RDC communicates with the
drive through the LAN. A single RDC can support up to 31 Remote Display
Units (RDUs). By means of a Portable Control/Display Unit (PCDU), the
RDC allows the selected display for each RDU to be changed at anytime.
●
Remote Display Unit (RDU) – Designed for mounting in a panel cutout, the
RDU provides a two-line LED display (16 character alphanumeric, and 5-1/2
digit numeric). It constitutes a terminal with the information on its display
transmitted to it by a Remote Display Controller LAN Node PCB (RDC).
●
Remote Keyboard Assembly – Designed for mounting on a panel with or
near a Remote Display Unit (RDU), the Remote Keyboard allows initiation
of RDU display changes without the need for a Portable Control/Display
Unit (PCDU) plugged into the Remote Display Controller LAN Node PCB
(RDC).
●
Remote I/O [Input/Output] Controller LAN Node PCB (RIO) – This
board provides a means for the DSD system to have inputs or outputs at
locations remote from the DSD drive. The RIO communicates with the
drive through the LAN. A single RIO can support up to 6 Remote I/O
boards, using any combination of the following three available types.
● Remote Logic I/O PCB (LOGIO) – This board provides isolated and non
isolated remote logic signal input/output capability for the DSD system. It is
connected to a Remote I/O Controller LAN Node PCB (RIO) for
communication with the DSD drive.
●
Remote Analog I/O PCB (ANIO) – This board provides isolated and non
isolated remote analog signal input/output capability for the DSD system. It
is connected to a Remote I/O Controller LAN Node PCB (RIO) for
communication with the DSD drive.
● Remote Thumbwheel Switch I/O PCB (TWIO) – This board provides
remote thumbwheel switch input/output capability for the DSD system. It
can support up to 9 Thumbwheel Switch Assemblies. This board is
connected to a Remote I/O Controller LAN Node PCB (RIO) for
communication with the DSD drive.
●
Remote Programmable Logic Controller (PLC) Interface – Available for
PLCs from many major manufacturers. It allows bi-directional
communication via the MicroTrac LAN between DSD drives and the PLC.
Both logic and numeric data can be transferred.
●
Remote Power Supply – The Remote Power Supply produces control level
voltages for use by a Remote LAN Node PCB or a Remote Display Unit.
●
Remote Serial Communication Controller LAN Node PCB (RSC) – This
board provides a means for the DSD system to have input from or output to
other equipment that uses RS-232 serial communication. The RSC
communicates with the DSD drive through the LAN.
