FC-QPP-0001 | Honeywell Quad Processor Pack Module

Display on Quad Processor Pack (QPP) Figure 6 shows the user interface display, located on the Control Processor. It provides system status and diagnostic information.The messages are language-independent and include (if applicable) UNICODE languages. This means that messages will be displayed in English as a default, but this depends on the configured language in the Safety Builder. The QPP reads the process inputs and executes the application program created with the Application Editor. The results of the control program are transmitted to the output interfaces. In Safety Manager configurations with a redundant Controller, both QPPs synchronize their operation through a dedicated redundant communication channel, integrated in the Controller backplane. Through continuous testing of Safety Manager hardware and software integrity, the QPP ensures safe operation as well as extensive diagnostics.The QPP contains a watchdog circuit. It automatically monitors the correct functioning and the operating conditions of the QPP safety processors. The watchdog circuits include the following functions:• A unique feature of the Safety Manager watchdog is that it verifies if the processor executes its tasks within the defined cycle time.• The monitored operating conditions include the data integrity check of the processor memory and the voltage range check of the supply power (under voltage and over voltage).• Deactivate the safety-critical outputs of Safety Manager, regardless of the QPP status, whenever required.The QPP is also equipped with the following items:• 4 bus drivers to drive the IO chassis• A status LED• Display to show time, date, system information, system status and diagnostics• Key switch
