Allen-Bradley 1771-HODS Converter ODS Module

Allen-Bradley 1771-HODS Converter Option ODS Module for PLC-5

Product Introduction

The Allen-Bradley 1771-HODS is a specialized Converter Option ODS module. It belongs to the PLC-5 series and works specifically with the 123 Motion Control System. This module acts as a communication bridge. It connects both the ODS terminal and the handheld pendant to the motion controller module. Furthermore, it supports two communication protocols. These are RS-232 for handheld pendant connections and RS-422 for ODS terminal connections. The module also offers a longline option. With this feature, you can extend connections up to 393 meters. This flexibility makes remote programming and diagnostics much easier.

Key Technical Specifications

The 1771-HODS supports dual communication interfaces. Specifically, it uses RS-232 for handheld pendant communication. Meanwhile, it uses RS-422 for ODS terminal communication. The module is part of the PLC-5 series. It is fully compatible with the 123 Motion Control System. For mounting, the module installs on a standard DIN rail. This makes integration into existing control cabinets simple. Additionally, the module works with the 1771-HLL longline option. This accessory extends the communication distance significantly.

Communication Distance Capabilities

The 1771-HODS offers impressive communication range. Without the longline option, the handheld pendant connects up to 8 meters (25 feet). This connection uses the RS-232 port on the motion controller. For the ODS terminal, the standard RS-422 connection reaches up to 393 meters (1200 feet). Therefore, you can position the ODS terminal far from the controller. When you add the 1771-HLL longline option, both connections extend further. The handheld pendant can then reach up to 1200 feet. Similarly, the ODS terminal maintains its 1200-foot range. This longline capability provides exceptional installation flexibility.

Termination Panel Options

The 1771-HODS module supports four available termination panels. Each panel mounts on a DIN rail for easy installation. First, there is the Temposonic panel. This panel supports Temposonic linear displacement transducers. Second, the Encoder panel supports one axis of encoder feedback. It also includes additional external power for encoders. Third, the Resolver panel supports one axis in single resolver configurations. Fourth, the same Resolver panel also supports dual resolver configurations. These termination panels expand the module's application range. Consequently, you can interface with various feedback devices.

Installation and Setup Guide

First, select the appropriate termination panel for your application. Mount the panel onto a standard DIN rail. Next, install the 1771-HODS module in the PLC-5 chassis. Ensure the backplane connection is secure. Then, connect the communication cables. For the handheld pendant, use the RS-232 port. For the ODS terminal, use the RS-422 connector. If using the longline option, install the 1771-HLL module as well. After that, connect your feedback devices to the termination panel. Verify all wiring matches the panel type. Finally, power up the system and test communication. The module should establish connections to both programming devices.

Frequently Asked Questions (FAQ)

1. What is the primary function of the 1771-HODS module?
The 1771-HODS acts as a communication converter. It connects ODS terminals and handheld pendants to the 123 Motion Control System. It supports both RS-232 and RS-422 protocols for flexible connectivity.

2. How far can I place the ODS terminal from the controller?
With the RS-422 connection, the ODS terminal reaches up to 393 meters (1200 feet). The 1771-HLL longline option provides the same extended range for handheld pendant connections.

3. What termination panels work with the 1771-HODS?
There are four panels available. These include Temposonic, Encoder (1 axis), and Resolver (single or dual configuration) panels. Each panel mounts on a DIN rail and supports different feedback devices.

4. Can I use the handheld pendant with the longline option?
Yes, the 1771-HLL longline option extends the handheld pendant's range. It reaches up to 1200 feet from the RS-232 port. This is the same extended distance as the ODS terminal.

5. Is the 1771-HODS compatible with other PLC systems?
This module is specifically designed for the PLC-5 series. It works with the 123 Motion Control System. It may not be compatible with newer platforms like ControlLogix or CompactLogix.
