PENDAHULUAN
A programmable logic controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. Fundamentally, a PLC’s job is to control a system’s functions using the internal logic programmed into it. This training will learn about PLC , that has been designed for system solutions in the fields of manufacturing and process automation. This process controller is ideal for data-intensive tasks that are especially typical for the process industry.
MATERI
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)
- Check all settings against a template, Node Address etc
- Check Hardware Configuration
- Clear Memory and Download program
- Check software against latest copy (Compare function)
- Monitor program
- Searching for specific operands and instructions
- Changing timer, counter values On Line
- Making minor mods Off Line and On Line
- Check or create a VAT table to establish parameter status
- Force a parameter if required
- Call up reference data to assist with software diagnostics
- Archive and Retrieve project
- Display Documentation (Symbols, Comments)
- Reassign an I/O address and change software addresses (Rewire Function)
- Printing Cross Reference/Program Listings etc
3. Background Information Also Covered
4. Understanding of The Following
- Number formats, bits, bytes, words, double words
