IOF_DeviceReset

IOF_DeviceReset 1:

The IOF_DeviceReset function block resets an IO device (e.g. a fieldbus card). The function corresponds to the online reset function from the TwinCAT->I/O->Devices->Device xyz context menu.

VAR_INPUT

VAR_INPUT
    NETID     : T_AmsNetId;
    DEVICEID  : UDINT;
    RESET     : 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: DeviceID specifies the I/O device on which the function is to be executed. The device IDs are specified by the TwinCAT system during the hardware configuration.

RESET: 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;
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.
