|Belum ada jadwal terbaru|
- 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
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
2. How Do I Do The Following?
- How do I check power is ON and PLC is in right mode (RUN or Program)
- Check for a fault condition (is SF LED ON)
- Establish a link to the PLC (accessible nodes)
- If comms problem check PG/PC interface
- Create a blank project and take a backup
- Open project for PLC and go On Line
- Interrogate Diagnostics Buffer
- Identify if it is a hardware or software fault?
- Change the battery
- Change modules if necessary (with spares and without spares)
- Identify if it is a PLC or comms fault (Profibus or MPI)
