Features

• Connects to Allen-Bradley SLC5 or Micrologix Programmable Controllers.

• Supports DF1 Serial, Ethernet, or DH485 (using a DF1-DH485 adapter module).

• Scanner automatically optimizes communications for fast access.

• Written in 100% Pure Java - no native libraries, no RSLinx installation required. Portable to any system that supports JDK 1.3 or higher (subject to availability of the javax.comm package for serial connections).

• Define symbolic tags using standard A-B addressing format. For instance, you can define a tag named "Temperature.Northwest" that maps to address "N7:201".

• Supports all basic data types, including timers and counters.

• Tags and scan sets are declared within an XML-formatted text file. You can use standard XML tools to manage the configuration. Also, since it's a text file, it is compatible with standard revision control tools.

• JSP Tag library lets you include PLC data in web pages using a syntax similar to HTML. For instance, putting "<plc:tag name='Temperature.Northwest'/> substitutes the data read from the PLC in your HTML output. Includes a preconfigured installation of Apache Tomcat with the ABConnect web application already set up. Define tags, then use them in web pages. It's that simple!

• Automatically provides input scaling and number formatting. For instance a PLC value that ranges from 0-905 could be scaled to mean 0 - 90.5

• You can also create an instance of the scanner from within any Java application. You could use this facility to write portable HMIs, flexible data logging, or interface with enterprise systems.

• In addition to the scanner component, a low-level library allows for direct read and write to PLC tag memory. For DF1 serial connections, you can directly encode and decode DF1 communications packets.
