System Overview
A basic MicroLogix 1500 system consists of a base unit that provides 24 or 28 built-in basic I/O, a built-in AC or DC power supply, and a processor module that slides into the base unit. You can supplement the I/O built into the base unit with up to sixteen digital and/or analog input and output 1769 Compact™ I/O modules (depending on current draw and power dissipation). Add an optional memory and/or real-time clock module or an optional Data Access Tool to enhance system capability.
Benefits
No chassis required—The base unit and Compact I/O modules of the MicroLogix 1500 system can be either panel- or DIN rail-mounted. There is no chassis or rack for expansion I/O.
Expandable I/O—You can enhance I/O capacity by adding up to sixteen Compact I/O modules (1769 series). Add I/O modules directly to the base unit, or up to a meter away using the available expansion cables and power supplies. Compact I/O modules can be inserted and removed from the front individually.
MicroLogix and SLC 500 compatible instruction set—Programs written for other MicroLogix or SLC 500 processors can easily be modified to work on a MicroLogix 1500 controller.
Compatible with RSLogix 500 Programming Software—This feature-rich, user-friendly, Windows-based programming software enables fast program development and increased reusability of programs.
Easy Interface to System Resources—Built-in function files provide efficient and logical interface to controller resources such as high-speed counters, analog trim pots, or selectable timed interrupts.
Wide Range of Communication Options—A built-in RS-232 port supports DF1 full- and half-duplex protocols (master as well as slave), Modbus RTU slave protocol (master available late 2003), Radio modem protocol, and full ASCII read and write communication. You can connect the MicroLogix 1500 controller to DH-485, DeviceNet, or EtherNet/IP networks through optional communication interface modules.
Ease of Wiring and Installation—Removable finger-safe terminal blocks on base units and Compact I/O modules ease wiring, installation, or replacement while meeting global safety standards.
On-line Data Monitoring and Adjustment—The optional Data Access Tool (DAT) lets you monitor and adjust user-defined integer and bit data. You can insert or remove the DAT while the controller is running.
Field-upgradeable flash operating system—You can update the controller firmware by using the ControlFlash tool. Controller enhancements can now be downloaded in the field, protecting your investment.
High-Speed Input and Output Functions—High-speed embedded inputs and outputs allow cost-effective development of both high-speed applications and simple motion control applications without the need for larger or more dedicated controller systems.
