1756HP-GPS | Allen-Bradley | HiProm ControlLogix Global Positioning Module

Product Overview

The 1756HP-GPS acts as a high-precision satellite receiver module designed specifically for the Allen-Bradley ControlLogix platform. It integrates Global Positioning System (GPS) data directly into the PLC backplane, providing nanosecond-accurate time synchronization and geographic coordinates for distributed industrial networks. We offer this unit in 100% Brand New condition, ensuring a high-integrity solution for synchronized power grid monitoring, mobile asset tracking, and wide-area timestamping applications.

Technical Specifications

Engineering Advantages

• Eliminate Time Drift: This module provides an Stratum 1 level time source directly to the ControlLogix backplane. It synchronizes multiple PLC racks across vast distances without relying on vulnerable local NTP servers or manual clock adjustments.

• Precise Geofencing and Tracking: For mobile machinery or shipboard automation, the 1756HP-GPS streams real-time latitude, longitude, and altitude data into the controller's tag database. This allows for automated geofencing logic and precise location-based interlocking.

• Seamless Backplane Integration: The module occupies a single slot in the 1756 chassis. It communicates via standard Producer/Consumer tags, allowing the CPU to access complex satellite data without requiring external serial-to-Ethernet converters or complex ASCII parsing.

• Reliable Data Logging: By applying a GPS-derived timestamp to localized event logs, the 1756HP-GPS ensures that sequence-of-events (SOE) data remains consistent across the entire enterprise, which is critical for fault analysis in power distribution and oil & gas midstream operations.

FAQs

Does the 1756HP-GPS require an external antenna?

Yes. To acquire satellite signals, you must connect a high-quality active GPS antenna via the SMA port on the front of the module. Ensure the antenna has a clear view of the sky for optimal satellite lock and timing accuracy.

How does the module handle signal loss in indoor environments?

The module features an internal high-stability oscillator that "holds" the time during brief satellite signal interruptions. However, for permanent positioning data, the module requires a continuous line-of-sight to at least four satellites.

Is this module compatible with modern Studio 5000 software?

Absolutely. While the manufacturer has discontinued the series, our Brand New 1756HP-GPS units remain compatible with standard ControlLogix controllers. You simply import the provided Add-On Profile (AOP) or use Generic Module configuration to map the I/O tags.

Can I use the 1756HP-GPS as a Master Clock for my entire plant network?

Yes. You can configure the ControlLogix CPU to read the GPS time from this module and then distribute it as a Grandmaster clock to other PLCs, HMIs, and drives using the Precision Time Protocol (PTP/IEEE-1588) over EtherNet/IP.
