INTRODUCTION
HARDWARE
The Allen-Bradley Programmable Logic Controller (PLC) Remote I/O
Gateway allows any drive on the MicroTrac®LAN to communicate with an
Allen-Bradley PLC-5 or PLC-3 through the 1771 I/O Network. Both logic
and numeric information can be transferred.
CAUTION
The gateway must be properly grounded. Use star washers that
will cut into the metal of the gateway box when mounting to
ensure proper earth ground.
The Allen-Bradley PLC gateway is a self-contained unit with one JARC
interface board, one SmartMUX interface board, one eight-point local I/O
interface board, and a power supply. The NEMA 1 enclosure contains the
electronics with internal connections for AC power, digital I/O points, and
external connections for the MicroTrac LAN. The initial setup is factory
configured, but depending on the application, the following electronic boards
may require setup.
1. The JARC board is the interface board which provides the LAN
connection and communicates with the SmartMUX board through dual port
memory contained on the JARC board. A 12-position DIP switch on the
JARC board, labeled SW1, sets the LAN node address (default = 200) and the
rack address (default = 1). Refer to Figure 1.

2. One SmartMUX board is attached to the JARC board using screws and a
pluggable 17-pin header. Two 6-position DIP switches on the SmartMUX
board, labeled SW1 and SW2, set the rack address and the baud rate for the
communications. Refer to Figure 2.

JARC Board Setup
12/22/94- RD 3196-10
The JARC board has jumpers and one 12-position DIP switch that are user
configurable.
NOTE: The JARC board only reads the DIP switch settings on
power-up.
The proper version of EPROM must be placed in the EPROM socket.
The jumpers located on the JARC board are described in Table 1, with the
defaults shown.
NOTE: On revision "C" and later JARC boards, J1 is an ARCNET
BNC connector and J2 does not exist.
NOTE: If the hand held Portable Command/Display Unit (PCDU)
does not operate properly after plugging into the JARC board J3
RS-232 connector, check the F1 fuse. This fuse protects the +5V
power to the PCDU.
Positions 1 through 8 of DIP switch SW1 determine the LAN node address.
Usually this address is set for 200, when the system has only one PLC gateway.
The address of the second PLC gateway is typically set to 201. Enter the node
ID in binary notation, choosing either a "0" or a"1" for each bit. The least
significant bit is position 1, and the most significant bit is position 8. The
standard gateway addresses are listed in Table 2. The JARC board switches use
pull-down logic, so a closed switch is a logic 0.

JARC Board DIP Switch
Positions 9, 10, and 11 of DIP switch SW1 determine the starting rack number
for the JARC board to accept on the network (see Table 3). This rack number
must match the lowest rack number selected on the SmartMUX board. The
SmartMUX board is usually wired to JARC board connector J5. Rack 0 is only
valid for a PLC-3.

12/22/94- RD 3196-10 JARC Board LED Operation
Position 12 of DIP switch SW1 enables or disables the hardware watchdog (see
Table 4). The hardware watchdog resets the JARC board if a hardware or
software failure occurs. This feature should be enabled for all installations.
There are four LEDs on the JARC interface board; one power LED and three
user indication LEDs. The placement of the LEDs is shown in Figure 1.

Table 5. JARC Board LED Operation
LED COLOR DESCRIPTION
PWR RED ON when the JARC board has proper +5V power from the
power supply. The power LED should always be ON.
RECON YELLOW ON when a LAN reconfiguration occurs. Each time a node
enters or leaves the network, a reconfiguration occurs. If the
reconfiguration completes and the network is stable, the
RECON LED will turn OFF after about 1-2 seconds. If this
LED is ON constantly or blinks frequently, a network problem
is likely.
XMIT RED ON when the JARC board is communicating on the network.
This LED is normally on all the time.
PGM RED The PGM LED is used to indicate hardware error conditions.
If this LED is ON, turn off the power to the PLC gateway and
then turn the power back on. If this LED remains ON, then a
hardware problem has been detected with the JARC board.

Board Baud
Rate / Last
State
The SmartMUX board resides on top of the JARC board and is screwed in
place. The SmartMUX board requires four screws to attach it to the JARC
board.
There are two jumper positions on the SmartMUX board, labeled J1 and J2.
These jumpers are used for EPROM functions which are not required by this
implementation of the SmartMUX board, so these jumpers are not installed.
The SmartMUX board has two 6-position DIP switches, labeled SW1 and
SW2, to select the rack address and baud rate. The rack address must be
consecutive between zero and seven (inclusive), and must match the rack
address set on the JARC board.
The first DIP switch, SW1, controls the baud rate, last I/O group, last state,
and watchdog (see Tables 6-9), and one bit of the rack address. The "Baud
Rate" and "Last State" should be the only switches that require modification.
