IOF_GetDeviceType

VAR_INPUT

VAR_INPUT
    NETID     : T_AmsNetId;
    DEVICEID  : UDINT;
    START     : BOOL;
    TMOUT     : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

NETID: The network address of the TwinCAT computer on which the function is to be executed can be entered here (type: T_AmsNetID). If it is to be run on the local computer, an empty string can be entered.

DEVICEID: The ID of the device whose device type is to be read

START: the block is activated by a positive edge at this input.

TMOUT: States the length of the timeout that may not be exceeded during execution of the command.

VAR_OUTPUT

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

BUSY: When the function block is activated this output is set. It remains set until a feedback is received.

ERR: If an error should occur during the transfer of the command, then this output is set once the BUSY output was reset.

ERRID: Supplies the ADS error number when the ERR output is set.

IODeviceType: The device type constant (type: IODEVICETYPES).

Example:

PROGRAM MAIN
VAR
    GetDeviceType1 : IOF_GetDeviceType;
    Start_GetType  : BOOL;
    GetType_Busy   : BOOL;
    GetType_Err    : BOOL;
    GetType_ErrId  : UDINT;
    DeviceType     : IODEVICETYPES;
END_VAR
