DESCRIPTION
- Be able to recognize S7 hardware and be able to replace modules when a fault occurs
- Be able to operate the Step 7 software to make it perform certain tasks
- Understand basic S7 instruction set and be able to make minor modifications to software
- Be able to backup and restore a PLC program when required
- Be able to perform basic system diagnostics when a problem occurs
COURSE OUTLINE
1. How Exactly Does A PLC Work?
- The Led on the output card means i am getting voltage out right? Does it?
- What exactly happens in between? There’s more than just a program in the CPU
- How exactly does it scan the program?
- What is this Watchdog Timer? Is it that important?
- Can I use the same output twice? That’s bad programming isn’t it?
- A PLC is a logic controller, so use a logical approach to fault find it
- What are the 8 simple test points to check?
- The PLC is in RUN, that means there’s a program right? Does it?
- FORCING a bit and toggling a bit is pretty much the same yeah? Depends on which PLC
