Chapter 9 Diagnostics
This chapter explains the PACSystems fault handling system, provides definitions of fault extra data,
and suggests corrective actions for faults.
Faults occur in the control system when certain failures or conditions happen that affect the
operation and performance of the system. Some conditions, such as the loss of an I/O module or
rack, may impair the ability of the PACSystems controller to control a machine or process. Other
conditions, such as when a new module comes online and becomes available for use, may be
displayed to inform or alert the user.
Any detected fault is recorded in the Controller Fault Table or the I/O Fault Table, as applicable.
Information in this chapter is organized as follows:
▪ Fault Handling Overview
▪ Using the Fault Tables
▪ System Handling of Faults
▪ Controller Fault Descriptions and Corrective Actions
▪ I/O Fault Descriptions and Corrective Actions
▪ Diagnostic Logic Blocks (DLBs)
