Lesson 1.2 RS LINX & RS LOGIX 5000

RSLinx RSLinx is a collection of drivers to connect programming software in the PC to Allen Bradly controllers such as ControlLogix, SLC-500, PLC- 5 and other devices. Drivers are included for all communication methods used by AB products.

RSLinx Versions There are several versions of RSLinx to meet the cost and functionality of different applications ranging from basic communications (RSLinx Classic Lite) to those able to transfer data to third party packages such as Microsoft Excel and Access. RSLinx Classic Lite RSLinx Classic Single Node RSLinx Classic OEM RSLinx Classic Gateway RSLinx Classic for Factory Talk View

RSLinx RSLinx has drivers for all Allen-Bradley products including RS-232 serial, Ethernet, Ethernet/IP, DeviceNet, and ControlNet USB drivers are added starting with RSLogix 5000 version 20 and are Configured to RSLinx the first time the Software detects a USB-enabled Controller.

RSLogix 5000 RSLogix 5000 software enables the user to develop ControlLogix projects using 4 different languages. It is possible to use all of the programming languages within a single project. Sequential Function Chart (SFC) Structured Text Functional Block Diagram (FBD) Ladder Logic

Sequential Function Charts Uses a flowchart-like language that uses steps and transitions to control a process or application. Effective method of programming an application that uses fixed sequence of inputs and outpus.

Structured Text High level programming language that uses text statements to define the operation of the PLC. Often used in PLC applications that involve a lot of math or data conversion.

Function Block Diagram Graphical Programming language that encapsulates other programming language into blocks. The blocks are assembled and connected together so that it appears similar to an electronic circuit. Mostly used when applications involve a high degree of information flow between control components, such as process control.

Ladder Logic Resembles a ladder with rungs. Looks and operates very similar to hardwired relay systems.

Who Active Utility Found in both RSLinx & RSLogix 5000 Who Active is a network search utility that shows the layout of every network that has a driver configured in RSLinx In RSLogix 5000 the utility helps the user locate the PLC to download, upload, or monitor projects.
