2. Machine Communication
2.1 Remote Termination Unit
The Remote Termination unit is a microprocessor
based fully encapsulated module that replaces the
diode at the end of the pilot conductor of the
trailing cable. It is powered by and communicates
via the pilot line. Its non-volatile memory stores the
parameters to configure the outlet as appropriate for
that machine.
All terminals are fully shrouded, with the pilot and
earth terminals being kept segregated from the
other terminals. (See RTU-2 General Case
Dimensions, Drawing IPB-A-021, Page 26)
The Remote Termination Unit (RTU-2) provides
remote stop, start facilities of the IPC Relay’s
controlled outlet. The circuitry involved for these
functions are self-diagnostic and will cause the
outlet to turn off if the circuits are earthed or
interconnected. This reduces the chance of the
outlet operating when not required to do so due to
wiring faults. It should be noted that these functions
are operational only, and that any
emergency stops
should be wired direct into the pilot circuit.
PTC terminals are provided for a semiconductor
thermistor
connection. These terminals are
protected in a similar manner to the stop and start
circuits.
If the remote stop, start and PTC functions are
not required, each set of terminals must be
bridged, or the IPC Relay will not energise.
Four RTD inputs are provided for PT 100
temperature measuring devices. These terminals
could also be used with resistor networks to provide
digital information back at the IPC Relay.
RX, TX and 0V terminals are included for the
connection of auxiliary devices such as the RTU-
CIU1. These terminals allow the input of data from
an RS232 source at the load to be transmitted
through the pilot of the cable to the IPC Relay’s
communication port.
On/Off Line Status, machine type, machine
number, software version and input status of the
Remote Termination Unit can be examined by
selecting “Machine Module Information” (Level 2,
Positions 1-2). RTD temperature and CIU data is
available, Level 2, Position 4-5.
2.2 Machine Type Codes
There are 26 selectable machine type codes
available for use in the Remote Termination Unit.
The descriptive code is transmitted to the IPC
Relay to identify the type of machine connected to
the outlet. The codes are selected using the Remote
Display Module (Level 9, Position 1).
