Process diagnostics provide support with the following basic functions:

• PLC functions using SIMATIC S7-PDIAG
	• Fault detection - set points and actual values of the process signals are compared in the application program
	• Error message with date and time is passed on to the HMI system
	• First-up recording of the relevant signal statuses of the involved operands, which exist at the time the fault, occurs

• HMI functions using SIMATIC ProAgent:
	• Criteria analysis for determination of signals causing faults - fault detection, fault display and fault elimination.
	• Fault detection is carried out by the application program of the SIMATIC S7 CPU
	• Faults are displayed on an HMI device using SIMATIC ProTool or WinCC and ProAgent. All texts, symbols and addresses required for fault display are automatically obtained from the common data archive of the PLC program using a generation procedure.
	All texts, symbols and addresses required for fault display are automatically obtained from the common data archive of the PLC program using a generation procedure. • SIMATIC ProAgent provides a standardized sequence display for fault elimination
