Scope
This hands-on course is designed to continue where the Level 1 course left off. Essential
information from the Level 1 course will be discussed at the beginning of this course. The results of the pre-test will be
used to determine what information that your particular group needs to have reviewed. The focus of this course will be the
advanced instructions typically used when programming a PLC-5 processor. The instructor has used his over thirty years of
practical maintenance, control, and teaching experience to provide real world examples for each of the various instructions.
You will do many practical exercises and practice problems to help you understand the complex subjects of word to file, file
to file and file to word manipulation, file logic and math, file search, and file diagnostic instructions. You will have the
opportunity to program the various program control instructions to be able to see the effect that these instructions have
on the scanning sequence. You will be able to program, analyze, and troubleshoot the different types of synchronous and asynchronous
word and bit shift registers.
The gathering of data is essential for many of today’s
processes. The data is usually transferred into and out of a PLC-5 based control system by way of analog sensors and output
devices. To be able to effectively troubleshoot these data dominant systems, you will be instructed in both block transfer
and Data Highway Plus instructions. You will be given hands-on opportunity to install, program, and troubleshoot a "mini-highway"
containing various types of I/O modules and PLC-5 processors.
Even though relay logic diagrams have been the dominant language
of programmable logic controllers since their invention in 1969 many programmers have started to migrate into higher level
languages. You will learn how to enter, edit and troubleshoot Sequential Function Chart programs, Allen-Bradley’s first
introduction to a transitional higher level language.
The final part of the course will introduce you to installing
and troubleshooting ControlNet, Allen-Bradley’s new generation of automation and control networks. A discussion of this
"non-proprietary" communication hierarchy will be presented.
Prerequisites: Successful completion
of the Level 1 - Troubleshooting the Allen-Bradley Family of Programmable Logic Controllers or equivalent knowledge.
