PROFIsafe Status and Diagnosis

Problems that the safety controller has detected can be diagnosed in three places:

Problems are reported to the PROFINET Host (master controller) by means of the usual PROFINET diagnostic mechanism with a diagnostic code.
In CODESYS, the diagnostic information is displayed as status messages on the Status tab of each F-Module. See Object: 'F-Device Module' (below the standard controller)
In the standard application, the diagnostic codes are available by means of the instance of the ProfinetFDevice function block. Every F-Module that is displayed in the device tree has a driver instance from the function block ProfinetFDevice. For more information: see ProfinetFDevice (FB)

DiagCode	Description
Errors in the received F-Parameters I (standardized error codes):
`16#0040`	Discrepancy of the destination address `F_Dest_Add` for the configuration in the application
`16#0041`	Invalid destination address `F_Dest_Add`
`16#0042`	Invalid or non-matching source address `F_Source_Add`
`16#0043`	The watchdog time is 0 ms (`F_WD_Time`, `F_WD_Time_2`).
`16#0044`	The parameter `F_SIL` is greater than the SIL of the specified device.
`16#0045`	The parameter `F_CRC_Length` does not match the generated values.
`16#0046`	The version of the F-Parameter is incorrect.
`16#0047`	The data of the received F-Parameter blocks are inconsistent (CRC1 error).
`16#004C`	`F_Block_ID` is not supported.
Errors in cyclic communication (standardized error codes):
`16#004D`	Transmission error: Data is inconsistent (CRC2 error)
`16#004E`	Transmission error: Timeout (`F_WD_Time` or `F_WD_Time_2` was exceeded)
Internal errors in the interface from safety controller to standard controller:
`16#0100`	The request for an IO Service could not be sent within the watchdog time.
`16#0101`	The expected response for an IO Service was not received within the watchdog time.
`16#0102`	The response for an IO Service has an invalid format or contains invalid data.
Errors in the received F-Parameters II (CODESYS-specific error codes):
`16#0110`	The number of received F-Parameter bytes is invalid (`F_Block_Id` and the transmitted length do not match)
`16#0111`	Setting the F-Parameter is not supported by the module.
