High Functionality in a Compact,

Cost-Effective Package

Some micro-PLCs force you to trade off between product size and functionality.

Many applications requiring dedicated control also have rigorous space requirements. You may, however, want the freedom to expand your I/O as your application grows. Whatever the solution, though, it must be cost-effective.

With the MicroLogix 1200 family of micro-controllers, you can finally have the ideal blend of functionality and compact size, at a price that is more reasonable than you might expect.

The Footprint is Small, but the Functionality is Big

In 1994, we introduced the MicroLogix 1000, a miniature controller offering task-specific dedicated control at a very low price. Later came the MicroLogix 1500 with expansion

I/O to suit complex, ever-growing applications.

Now there is the MicroLogix 1200, bringing together the best of both products.

The MicroLogix 1200 controllers are truly micro in size. With a footprint as small as

3.54" x 4.33" (90mm x 110mm), they are ideal for control projects where panel space is a challenge. Make no mistake, though — small size does not mean small functionality.

These tiny packages are filled with an abundance of features designed to accommodate a broad range of applications.

Expansion I/O

The MicroLogix 1200 makes use of discrete and analog expansion I/O modules (providing up to 88 points) for a lot of application flexibility.

Removable I/O labels with a writeon area make for easy field device identification to reduce valuable troubleshooting and maintenance time. Finally, finger-safe terminal blocks make for safe operation by meeting global safety standards.

Compatible Instructions

Sets and Programming

Software

Because it is part of the

MicroLogix/SLC family, the

MicroLogix 1200 features an instruction set that is compatible with other MicroLogix controllers as well as SLC 500 controllers.

That means that programs written for the MicroLogix 1000,

MicroLogix 1500 or SLC 500 can be easily scaled for the

MicroLogix 1200.

Likewise, the MicroLogix 1200 is compatible with Rockwell

Software RSLogix 500 programming software, a feature-rich Windows ® based package used to program a host of Allen-Bradley controllers.

The result of this compatibility — reduced time spent training personnel and developing applications due to software familiarity and program reusability.

Large Non-Volatile Memory

Similar to the MicroLogix 1500, the MicroLogix

1200 boasts a large 6K memory, with 4K words available for user programs and configurable

2K words for user data. This feature of the

MicroLogix 1200 expands application coverage by allowing data elements to be selected according to individual application requirements.

MicroLogix 1200 Features

Other features of the MicroLogix 1200 include:

• Real time clock & memory modules

• Communication features:

• Built-in RS-232C port supporting DF1 full and half-duplex protocols and

DH485 protocol

• New embedded Modbus RTU slave protocol

• Direct connectivity to either DeviceNet or

DH485 network interfaces

• 20 kHz High Speed Counter with eight modes of operation and direct control of outputs (independent of program scan)

• Built-in analog trim potentiometers

Analog I/O Module

The 1762-IF2OF2 analog combination input/output module converts and digitally stores analog data for use by the MicroLogix 1200 controllers. The module supports connections from any combination of up to two voltage or current analog sensors. The two output channels provide two single-ended analog output channels, each individually configurable for voltage or current. This provides application flexibility, reduces stock inventory and lessens the learning curve.

MicroLogix 1200 I/O’s analog module provides 12-bit resolution, making it an excellent choice for applications that monitor and control small changes in the analog value.

Communication Choices

All MicroLogix 1200 programmable controllers provide several communication options to fit into a variety of applications.

The DF1 Full-Duplex protocol allows the

MicroLogix 1200 to communicate directly with another device, such as a personal computer or an operator interface device.

The DF1 Full-Duplex protocol (also referred to as DF1 point-to-point protocol) is useful where RS-232 point-topoint communication is required.

The DH485 multi-drop communication capability allows you to network up to 32

MicroLogix or SLC 500 controllers,

Human/Machine Interface (HMI) devices and/or personal computers using peer-topeer messaging.

And, the MicroLogix 1200 can communicate on a DeviceNet network as well. DeviceNet digitally links push buttons, sensors, actuators, PLCs and other industrial devices on an open network.

MicroLogix 1200 controllers also support

DF1 Half-Duplex Slave communications for use in SCADA systems as a Remote

Terminal Unit (RTU). This open network protocol enables MicroLogix controllers to communicate as responder (slave) nodes on DF1 master/slave networks. DF1 supports up to 254 responder devices with a single master.

Additionally, the MicroLogix 1200 supports Modbus Slave, a SCADA/RTU protocol.

Communication Choices

Local Messages

The MicroLogix 1200 is capable of communicating using local or remote messages. With a local message, all devices are accessible without a separate device acting as a bridge. Different types of electrical interfaces may be required to connect to the network, but the network is still classified as a local network. Remote messages use a remote network, where devices are accessible only by passing or routing through a device.

1761-NET-DNI DeviceNet Interface Module

Highlights of the DeviceNet Interface’s capabilities are:

Peer-to-peer messaging between Allen-Bradley controllers and other devices using the DF1 Full-Duplex protocol

Programming and on-line monitoring over the DeviceNet network

With a DNI connected to a modem, you can dial in to any other DNI-controller combination on DeviceNet

Other DeviceNet products can send explicit (Get or Set) messages with the DNI at any time

The controller can initiate an explicit message to any UCMM

(Unconnected Message Manager) compatible device on

DeviceNet

MicroLogix micro-PLCs extend the benefits of distributed control to the device level of your process with the addition of DeviceNet functionality.

DeviceNet digitally links push buttons, sensors, actuators, PLCs and other industrial devices. It reduces the installation and maintenance costs of multiple discrete wires with a single cable that handles both communications and power distribution.

The 1761-NET-DNI Series B Interface

(DNI) brings the fast response, low cost and reliability of open DeviceNet connectivity to all MicroLogix controllers and most other Allen-Bradley controllers.

MicroLogix on DeviceNet lets you take advantage of the latest advances in communications. DeviceNet uses producer/consumer technology which significantly reduces the amount of traffic on the network, thus improving efficiency and data throughput. As a result, information gets across the network quicker.

Network Interface Devices

Advanced Slave I/O Functionality

Through the DNI, MicroLogix controllers can function as cost-effective DeviceNet slave nodes. The DNI presents to

DeviceNet up to 64 words of data (32 inputs, 32 outputs, configurable). The DNI can either poll or accept data sent from the MicroLogix controller to keep its mapped I/O data up-to-date with the actual data in the controller, while the DNI handles all DeviceNet communications.

All local I/O remains under the MicroLogix controller’s direct control, yet can be visible to the DeviceNet master.

Using standard messaging commands, you can easily read or write data to other controllers as shown in the network diagram on page 15.

Simple, Reliable Peer-to-Peer Messaging

The DNI brings brand-new functionality to DeviceNet by enabling peer-to-peer messaging between devices that use the

DF1 Full-Duplex protocol.

The DNI takes the DF1 Full-Duplex commands, wraps them in the DeviceNet protocol and sends them to the target

DNI. The target DNI removes the DeviceNet information and passes the DF1 command to the end device.

This capability works between controllers, PCs and controllers, and for program up/downloading. I/O and data messages are prioritized, which minimizes I/O determinism problems typically encountered on networks that support I/O and messaging simultaneously.
