Allen-Bradley ControlLogix
Intermediate II Programming & Troubleshooting
Module: 243

The Intermediate I course explored the Compare, Compute, Data Conversion, File Manipulation, and Message instructions. The Intermediate II course continues the investigation of the File Manipulation and introduces the Bit Manipulation instructions. Programs using these instructions include data gathering, calculations, date and time stamping, shift reports, data concentration, totalizing, averaging, etc. The Intermediate II course further develops the skills necessary to trace the flow of word information into, through, and out of logic programs using the Word and File manipulation instructions. This additional programming knowledge provides the ability to comprehend and troubleshoot detailed control circuits. In addition, students explore the system status and diagnostic data access instructions (SSV, GSV) to help diagnose and solve in-plant control problems more quickly.
The course length is four days. Rockwell Software’s RSLogix-5000 / Studio-5000 Logix Designer programming software is used to conduct this course. Module 242 Allen-Bradley ControlLogix Intermediate I Programming & Troubleshooting is a prerequisite.
