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.

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.

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.
