Master Function API Functions
Section 4-4
FILE_SCAN_DEV
This structure defines the format of the grouped Slave information used when
nodes are registered in the scan list as a group.
This structure is used in the SCAN_SetScanList() function.
Registering Multiple Slaves in the Scan List: SCAN_SetScanlist()
Application Range Open status
Function Registers multiple Slaves in the scan list as a group.
Call Format BOOL SCAN_SetScanlist(DWORD Handle , LPCTSTR FilePath ,)
Arguments
Return Value TRUE is returned if the scan list was registered successfully. FALSE is
returned if an error occurred. Detailed error information can be read with the
GetLastError() function.
4-4-2 I/O Communications Service API Functions
Starting Remote I/O Communications: SCAN_StartScan()
Application Range Online status
Function Starts remote I/O communications.
Call Format BOOL SCAN_StartScan(DWORD Handle , BOOL ErrStop )
Arguments
Return Value TRUE is returned if remote I/O communications started normally in the speci-
fied Board. FALSE is returned if an error occurred, such as the lack of a corre-
sponding event. Detailed error information can be read with the
GetLastError() function.
Description Performs remote I/O communications with the Slaves registered in the scan
list.
Several seconds are required after this function is called before I/O communi-
cations will actually start.
Scan list operation API Functions must be used to create a scan list before
this function is called.
When TRUE has been specified for the ErrStop variable, remote I/O commu-
nications with all of the Slaves will be stopped if a communications error
occurs during remote I/O communications.
