PLCs: Troubleshooting Software, Part 2

Most PLC system problems are hardware related, and most of these are in the I/O systems. However, software and network problems do occur, and they are often the hardest types of problems to isolate. Isolating software and network problems takes a high degree of skill and a thorough understanding of the software tools that are available. This module will examine how to use the PLC programming software to troubleshoot software and network problems. It will also explore techniques and the hardware and software tools that are available for isolating software problems.
