IOF_GetBoxAddrByNameEx

IOF_GetBoxAddrByNameEx 1:

The IOF_GetBoxAddrByNameEx function block determines the fieldbus address of a box (box = slave, module, station), knowing the box name and the device name. If no fieldbus address is available, the function block returns a physical or a logical address. (In the case of the Beckhoff Lightbus, for instance, it is the physical box number in the fiber-optic ring, while in Profibus it is the station address). The box name and the device name are passed as strings to the function block, and can be specified by the user during the configuration in the TwinCAT system.

Inputs

VAR_INPUT
    NETID       : T_AmsNetId;
    DEVICENAME  : T_MaxString;
    BOXNAME     : T_MaxString;
    START       : BOOL;
    TMOUT       : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

Name	Type	Description
NETID	T_AmsNetId	The network address of the TwinCAT computer on which the ADS command is to be executed can be specified here. For the local computer an empty string may be specified.
DEVICENAME	T_MaxString	The device name of an I/O device as a string.
BOXNAME	T_MaxString	The box name as a string.
START	BOOL	The function block is enabled by a positive edge at this input.
TMOUT	TIME	Specifies the time-out period that must not be exceeded when the command is executed.

Outputs

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

Name	Type	Description
BUSY	BOOL	When the function block is enabled, this output is set and remains set until a feedback is received.
ERR	BOOL	If an error should occur during the transfer of the command, then this output is set once the BUSY output was reset.
ERRID	UDINT	Returns the ADS error number when the ERR output is set.
BOXADDR	UINT	The fieldbus address or logical address of the box.

Requirements
