Information About 1764-LSP

The Allen-Bradley 1764-LSP is a MicroLogix 1500 processor. This controller has integrated 7K user program capacity. This memory size is the total of the combined 3.65 KB User Program and 4 KB User Data. These program and data file sizes are user-configurable with a maximum user data capacity of 4K words. The processor memory also stores function files that are user-specified and are used as configuration data for system resources.

The 1764-LSP MicroLogix 1500 Processor has approximately 1 ms program execution time for a 1K-word program (including counter, bit, math instructions, and timer). Long-integer data files (32-bit signed integer, +/- 2 billion) can be created for use with embedded high-speed I/O and math instructions. Floating point data files can also be developed, each of which contains a maximum of 256 IEEE-754 floating point data elements.

The 1764-LSP Processor features one non-isolated RS-232-C port with ASCII, DF1 half-duplex, DF1 full duplex, DH-485, and Modbus protocols. It has two built-in Trim Potentiometers with a digital output range of 0-250 volts. These 3/4-turn analog potentiometers allow easy and quick adjustment of counters, set points, and timers. The 1764-LSP can be installed with MicroLogix base units such as 1764-24AWA, 1764-24BWA, and the 1764-28BXB. This processor can have the following real time clocks and memory modules installed: 1764-MM1, 1764-MM2, 1764-MM3, 1764-MM1RTC, 1764-MM2RTC, 1764-MM3RTC, 1764-RTC. The MicroLogix 1500 RTC modules comes with a Lithium battery for memory retention.

The 1764-LSP is a MicroLogix 1500 Controller that is manufactured by Allen-Bradley. This controller supports installation of up to Eight (8) local I/O modules as well as installation of expansion back where up to Sixteen (16) Compact I/O modules may be installed. This controller supports a maximum of 512 Inputs and outputs, which is the ideal I/O range of small machine or process applications. The MicroLogix 1500 controller are obsolete products therefore, this product is available as a spare part only. The 1764-LSP was declared discontinued on 06/30/2017.

The 1764-LSP features an integrated memory amounting to 7KB. This memory is partitioned to user program amounting to 3.6KB and 4KB user data. With the attachment to any base unit, this controller is able to use the integrated RS232 port which supports communication to Human Machine Interface (HMI), Supervisory Control And Data Acquisition (SCADA), Remote Terminal Unit (RTU) devices, and programing workstations. The RS232 port supports DF1, DH485, Modbus, ASCII protocols. The same port can be used to connect with PanelView 800 using the 1761-CBL-PM02 cable.

This controller is installed to MicroLogix 1500 base units such as 1764-24AWA, 1764-24BWA, and 1764-28BXB.

Frequently Asked Questions about 1764-LSP
Question: What is the purpose of the Allen-Bradley 1764-LSP controller?
Date Update:05/06/2025
Answer:

The 1764-LSP is a MicroLogix 1500 processor unit that provides control functionality for compact and standalone automation systems. It handles program execution, data storage, and device communication through its integrated memory and communication port. This controller is ideal for small machine-level applications where cost-effective and scalable control is needed. It is often used in packaging, materials handling, and HVAC control systems. Its ability to support up to 512 I/O points makes it suitable for a broad range of industrial automation tasks.

Question: What communication protocols does the 1764-LSP support?
Date Update:05/06/2025
Answer:

The 1764-LSP supports several communication protocols over its RS-232 port, including DF1 full-duplex and half-duplex, DH-485, Modbus RTU, and ASCII. This makes it versatile for connecting to HMIs, SCADA systems, and other serial communication devices. The port uses a point-to-point topology and can be connected using cables like the 1761-CBL-PM02. These protocols allow integration with various industrial networks and third-party devices. It also supports programming via the same communication port.

Question: Does the 1764-LSP support analog functions like potentiometer input?
Date Update:05/06/2025
Answer:

Yes, the 1764-LSP features two built-in digital trim potentiometers. These 3/4-turn potentiometers allow users to fine-tune analog parameters such as counters, timers, or thresholds. Their range corresponds to a digital value between 0 and 250. This feature is useful for quick manual adjustments in the field without reprogramming the controller. It enhances the controller’s flexibility in tuning system responses.

Question: Can the 1764-LSP be programmed while powered?
Date Update:05/06/2025
Answer:

Yes, the 1764-LSP supports online programming and removal under power, with up to 28 operations allowed. This feature allows engineers to update or troubleshoot logic without halting the entire system. Online edits enhance system uptime and reduce maintenance-related downtime. However, proper safety precautions must be followed when modifying live systems. This capability is crucial for dynamic industrial environments where minimal interruption is desired.

Question: Is the 1764-LSP controller still in production?
Date Update:05/06/2025
Answer:

No, the 1764-LSP controller was officially discontinued by Rockwell Automation on June 30, 2017. Although the product is no longer manufactured, it remains available on the market as a spare or refurbished unit. Many industrial systems still operate using MicroLogix 1500 controllers due to their reliability. Rockwell continues to provide documentation and migration guides to assist with upgrades to newer platforms. For new applications, migration to the CompactLogix family is recommended.
