MicroLogix 1000 Controllers
| Product Overview |
System Overview
|
The MicroLogix 1000 family provides small, economical programmable controllers. They are available in configurations of 10 digital I/O (6 inputs and 4 outputs), 16 digital I/O (10 inputs and 6 outputs), 25 I/O (12 digital inputs, 4 analog inputs, 8 digital outputs, and 1 analog output), or 32 digital I/O (20 inputs and 12 outputs) in multiple electrical configurations of digital I/O. The I/O options and electrical configurations make them ideal for many applications.
Benefits
- Compact design—Lets the MicroLogix 1000 controller thrive in limited panel space.
- Choice of communication networks—An RS-232-C communication port is configurable for: DF1 protocol for direct connection to a programming device or operator interface; DH-485 networking through a 1761-NET-AIC converter; DeviceNet networking through a 1761-NET-DNI interface; EtherNet/IP networking through a 1761-NET-ENI interface; or for half-duplex slave protocol in SCADA applications.
- Simple programming with your choice of programming device—You can program these controllers in familiar ladder logic with MicroLogix 1000 A.I. Series Software®, PLC 500 A. I. Series Programming Software, RSLogix 500™ Windows Programming Software, or the MicroLogix Hand-Held Programmer (1761-HHP-B30). This symbolic programming language is based on relay ladder wiring diagrams that simplify the creation and troubleshooting of your control program.
- Comprehensive instruction set—Over 65 instructions including simple bit, timer, and counter instructions, as well as instructions for powerful applications like sequencers, high-speed counter, and shift registers.
- Fast—Execution time for a typical 500-instruction program is only 1.56 ms.
- Choice of languages—Software and documentation are available in 5 languages. The hand-held programmer has 6 languages built in.
Product Design
The MicroLogix 1000 controller contains the power supply, processor, and all its I/O circuits packaged in a single unit.
- Four I/O sizes (10, 16, 25, and 32) cover many applications.
- Various electrical configurations of digital I/O offer you a controller that meets your electrical requirements:
- 24V DC inputs and relay outputs with a 24V DC power supply.
- 24V DC inputs and 24V DC FET and relay outputs with a 24V DC power supply.
- 24V DC inputs and relay outputs with a 120/240V AC power supply.
- 24V AC inputs and relay outputs with a 120/240V AC power supply.
- 120V AC inputs and relay outputs with a 120/240V AC power supply.
- 120V AC inputs and triAC and relay outputs with a 120/240V AC power supply.
- 24V DC inputs and relay outputs with a 24V DC power supply.
- Isolated relay contact outputs (at least two per controller). Allow outputs on the same unit to switch different control voltages.
- The 25-I/O models include 4 analog inputs and an analog output in addition to the 12 digital inputs and the 8 digital (contact) outputs.
Communication
MicroLogix 1000 controllers provide a built-in RS-232C port. This port can be used for the following types of communication.
| Communication | Description |
| Point-to-point communication | • Supports direct connection of programming and operator interface devices, and supports dial-in remote programming. |
| DF1 protocol | • Supports DF1 half-duplex slave protocol for connection to a modem in SCADA applications. |
| DH-485 communication | • Connect to a DH-485 network through an Advanced Interface Converter (1761-NET-AIC). • The DH-485 network may connect up to 32 devices. • The communication port provides for program upload and download. |
| DeviceNet communication | • Connect to a DeviceNet network of up to 64 devices through a DeviceNet Interface (1761-NET-DNI). • The DeviceNet Interface provides slave I/O and peer-to-peer controller communication. |
| EtherNet/IP communication | • Connect to an EtherNet/IP network through an EtherNet/IP-to-RS-232-C interface (1761-NET-ENI, 1761-NET-ENIW). • This module supports program monitoring and upload/download, data collection, and controller peer-to-peer communication. • It can also send e-mail messages via SMTP and display status and configuration information through a built-in Internet server. |
