Although diagnosing the fault can often be time-consuming and requires specialist knowledge and experience, rectifying it can be as simple as replacing an I/O module or reconfiguring a field device. The first thing to do when trying to find the problem in your PLC is to figure out if the problem is internal or external. In this article, I will focus mainly on internal issues.
- Timer instructions allow for on-delayed or off-delayed events.
- The software will vary depending on which brand of music player you purchase.

Resolution Boot into the Windows Recovery Environment, choose the Command Prompt option, and then execute the bootrec /fixmbr command. This command replaces the executable code in the MBR. If you select the first option, WinRE will then display the dialog box in Figure 13-8, which has the various recovery options.
