SCIT_GetErrorInfo 1:

The function block "SCIT_GetErrorInfo" reads the exact error cause and the precise location of a bus error that has occurred from the Interbus card addressed by the NETID and the PORT.


    NETID  : T_AmsNetId;
    PORT   : T_AmsPort;
    WRTRD  : BOOL;

NETID: The network address of the computer in which the card is installed can be entered here (type: T_AmsNetID). If the card is located within the same system, it is also possible to give an empty string.

PORT: Contains the ADS port number of the card that was assigned by the TwinCAT system (type: T_AmsPort).

WRTRD: The function block is activated by a positive edge at this value.

TMOUT: Maximum time allowed for the execution of the command.


    BUSY         : BOOL;
    ERR          : BOOL;
    ERRID        : UDINT;
    RESULT       : WORD;

BUSY: After activation of the function block the busy signal remains asserted until an feedback is received.

ERR: If an error occurs while the command is being transferred, the ERR output is set once the BUSY signal is cancelled.

ERRID: Returns the ADS error number in the case of error.

RESULT: Returns the result from the card (provided that fault-free ADS transport has occurred (ERR = FALSE)). RESULT = 0 identifies successful execution of the command. A value other than 0 contains the error number from the Phoenix card.

ERRORCODE: Provides information related to the error type (cf. the Phoenix card error descriptions).

ADDERRORINFO: Contains the error location if feedback from the card is negative (cf. the Phoenix card error descriptions).
