FILECLOSE

VAR_INPUT

VAR_INPUT
    NETID   : T_AmsNetId;   (* ams net id *)
    HFILE   : UINT;         (* file handle obtained through 'FILEOPEN' *)
    CLOSE   : BOOL;         (* close control input *)
    TMOUT   : TIME;
END_VAR

NETID : is a string containing the AMS network identifier of the target device to which the ADS command is directed. 

HFILE : is occupied by the file handle already created by FILEOPEN.

CLOSE : the ADS command is triggered by a rising edge at this input.

TMOUT : specifies the time until the abortion of the function.

VAR_OUTPUT

VAR_OUTPUT
    BUSY    : BOOL;
    ERR     : BOOL;
    ERRID   : UDINT;
END_VAR

BUSY : this output remains TRUE until the function block has executed a command, but at the longest for the duration supplied to the 'Timeout' input. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.

ERR : this output is switched to TRUE if an error occurs during the execution of a command. The command-specific error code is contained in ‘ErrorId’. If the function block has a timeout error, 'Error' is TRUE and 'ErrorId' is 1861 (hexadecimal 0x745). Is reset to FALSE by the execution of a command at the inputs.

ERRID : contains the instruction-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs.

Sample of calling the function block in FBD:

Here the file associated with the file handle (which was itself generated by ”File1Open") is closed again.
