SCIT_AlarmStop
The "SCIT_AlarmStop" function block serves as an auxiliary block in order to carry out an Alarm_Stop on the Interbus card that is addressed by the NETID and the PORT. An Alarm_Stop places the card in the PAR_READY state and resets all the outputs.

NETID : T_AmsNetId;
PORT : T_AmsPort;
WRTRD : BOOL;
TMOUT : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR
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.
VAR_OUTPUT
VAR_OUTPUT
BUSY : BOOL;
ERR : BOOL;
ERRID : UDINT;
RESULT : WORD;
ADDERRINFO : WORD;
END_VAR
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.
ADDERRINFO: If feedback from the card is negative, this contains additional error information (cf. the Phoenix card error descriptions).
