SCIT_GetErrorInfo
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. Internally, an ADSRDWRT function block is called, which has the parameters described in the TwinCAT System Manager Help.
VAR_INPUT
VAR_INPUT
NETID : T_AmsNetId;
PORT : T_AmsPort;
WRTRD : BOOL;
TMOUT : TIME;
END_VAR
NETID: The AmsNetId of the computer into which the card is fitted can be given here. If the card is located within the same system, it is also possible to give an empty string.
PORT: This contains the ADS port number of the card. The number is assigned in the System Manager.
WRTRD: The function block is activated by a positive edge at this value.
TMOUT: This gives the timeout duration that is passed on to the internal ADSWRTRD block.
VAR_OUTPUT
VAR_OUTPUT
BUSY : BOOL;
ERR : BOOL;
ERRID : UDINT;
RESULT : WORD;
ERRORCODE : WORD;
ADDERRORINFO: WORD;
END_VAR
BUSY: After activation of the function block the busy signal remains asserted until an feedback is received.
ERR: If an ADS error occurs while the command is being transferred, the ERR output is set once the BUSY signal is cancelled.
ERRID: Supplies the ADS error number when ADS error is true.
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).
