IOF_GetDeviceIDByName

IOF_GetDeviceIDByName 1:

The IOF_GetDeviceIDByName function block determines the device ID of an I/O device, knowing the device name. If successful, the function block returns the device ID specified by the TwinCAT system during configuration. The device IDs cannot be configured by the user.

Inputs

VAR_INPUT
    NETID      : T_AmsNetId;
    DEVICENAME : 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.
