waives any claim thereto.
THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR
IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR
A PARTICULAR PURPOSE AND BUYER HEREBY WAIVES ANY AND ALL CLAIMS THEREFORE.

Page 4: Introduction
INTRODUCTION INTRODUCTION 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. -
Page 5: Smartmux Board
HARDWARE 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. PWR LED (Red –... -
Page 6: Jarc Board Setup
HARDWARE JARC Board The JARC board has jumpers and one 12-position DIP switch that are user configurable. Setup 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. -

Page 9: Smartmux Board Setup
HARDWARE The SmartMUX board resides on top of the JARC board and is screwed in SmartMUX place. The SmartMUX board requires four screws to attach it to the JARC Board Setup 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. -

GENERAL OPERATION Logic outputs from a PAC schematic to a PLC can be visualized as shown in MicroTrac to Figure 4. Logic output (LOGO) PAC blocks send a logic value from the drive PLC (LOGO) to the remote device specified by the node, channel, and sub channel defined for that block. -
Page 15: Plc To Microtrac (Logi)
GENERAL OPERATION Logic inputs to a PAC schematic from a PLC can be visualized as shown in PLC to Figure 5. Logic input (LOGI) PAC blocks receive a logic value sent to the MicroTrac drive from the remote device specified by the node, channel, and sub channel (LOGI) defined for that block. -

GENERAL OPERATION PLC to Numeric inputs to a PAC schematic from a PLC can be visualized as shown in Figure 7. Numeric input (NUMI) PAC blocks receive a numeric value sent to MicroTrac the drive from the remote device specified by the node, channel, and sub (NUMI) channel defined for that block. -
Page 18: Plc Initialization Hardware And Signal Flow
GENERAL OPERATION PLC Access to The PLC can be used to change the value of drive setup parameters. In the example illustrated in Figures 8 & 9, the PLC can modify a parameter called Drive Setup “Master Line Speed”. This parameter is also accessible from the Standard Parameters Control Display Unit (SCDU), the Portable Control Display Unit (PCDU), and potentially from a Remote Display Unit (RDU) or a personal computer... -
Page 19: Plc Access To Drive Setup Parameters
GENERAL OPERATION There are two types of PAC blocks which can be used with the PLC initialization command. These are the GETN and RDCI blocks which allow the programmer to define drive setup parameters, each of which has a unique "function"... -

The channel designation follows the same conventions as the NUMI and NUMO channel conventions described above. The "PLC IN"... - Page 21 GENERAL OPERATION gateway. The fourth rung moves the latest data from the drive into a buffer for the transition detector of rung 2. The fifth rung executes the read from the PLC gateway. All 64 words can be handled with block transfers in the PLC Ladder, if the words are consecutive.

Page 22: Sample Plc Ladder Diagram
GENERAL OPERATION ABBREVIATION KEY DSD_INT = Drive network interface to the PLC. DSDTOPLC = Data transferred from the drive to the PLC. DSDTOPLC_OLD = Temporary storage of DSDTOPLC for detection of changes in value. LOAD_PLC = True indicates the value stored in the PLC is to be transferred to the drive. PLC_DATA = Data to be moved into the PLCTODSD register when the LOAD_PLC bit is true. -
Page 23: Pac Considerations
GENERAL OPERATION PLC initialization can access both RDCI and GETN blocks. The only difference between these blocks is the way each uses the battery backed up Considerations memory (NVRAM – nonvolatile random access memory). The RDCI block immediately writes directly to nonprotected NVRAM. The GETN block does not automatically write to NVRAM. -
