AB MicroLogix 1000 Control System

-
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.

 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.
  • 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.
Features
  • Available in 10-point, 16-point or 32-point digital I/O versions
  • Analog versions available with 20 digital I/O points, 4 analog inputs (two voltage and two current) and 1 analog output (configurable for either voltage or current)
  • Provides a compact form factor, with footprints as small as 120 mm x 80 mm x 40 mm (4.72 in. x 3.15 in. x 1.57 in.)
  • Offers fast processing with typical throughput time of 1.5 ms for a 500-instruction program
  • Preconfigured 1 KB program and data memory to ease configuration
  • Includes built-in EEPROM memory; no need for battery back-up or separate memory module
  • Provides peer-to-peer messaging (up to 32 controllers on a DH-485 network) through a 1761-NET-AIC communication interface
  • Communicates via DeviceNet™ and EtherNet/IP™ through 1761-NET-DNI and 1761-NET-ENI communication interfaces
  • Includes a built-in high-speed counter (only on controllers with 24V DC inputs)
  • Lets you customize input response time and noise rejection using adjustable DC input filters
  • Supports simple connectivity through RS-232 communication channel to a PC for program upload, download and monitoring

I/O Adapter Modules      1747 I/O adapter modules allow 1746 I/O modules in a remote chassis to be controlled by SLC and PLC processors. SLC processors require a scanner module to reside in the local chassis in order for the remote communication to occur. The adapter module must reside in the left-most slot of the remote chassis and can interface to a maximum of 30 1746 I/O modules residing in up to three interconnected chassis. There are three 1746 I/O adapter modules: the 1747-ASB for remote I/O communication, the 1747-ACN15 for remote communication via ControlNet, and the 1747-ACNR15 for remote communication via ControlNet with redundant media port.

DCS or PLC ? Seven Questions to Help You... Select the Best Solution... Distributed Control Systems (DCS) or Programmable Logic Controllers (PLC)         For manufacturers in the process industries, the procedure for selecting the best automation technology is not as easy as it once was. In the past it was fairly easy to determine whether a PLC or a DCS was right for your application, because their strengths and weaknesses were well understood. In recent years this has become more difficult, thanks primarily to the advancement of the microprocessor, which has allowed the technologies to merge. With the trend toward flexible manufacturing in industry, many of the applications in the process industries now share the requirements traditionally thought to be exclusive to either DCS or PLC. These hybrid applications typically require a process control system that can deliver both PLC and DCS capabilities. Thus understand-ing the merging of PLC and DCS functionality i...
