Format LONG LJV7IF_SetTime(LONG lDeviceId, LJV7IF_TIME* pTime);
Parameters
lDeviceId(in)
Specifies the communication device to communicate with.
pTime(in)
The date/time to set.
For each member, see "8 Constant, Structure Definitions".
Return value No individual return code
Explanation This function sets the date/time for the controller.
Supported version 1.00
Format LONG LJV7IF_GetTime(LONG lDeviceId, LJV7IF_TIME* pTime);
Parameters
lDeviceId(in)
Specifies the communication device to communicate with.
pTime(out)
The buffer to store the acquired date/time.
For each member, see "8 Constant, Structure Definitions".
Return value No individual return code
Explanation This function gets the date/time from the controller.
Supported version 1.00
Format LONG LJV7IF_ChangeActiveProgram(LONG lDeviceId, BYTE byProgNo);
Parameters
lDeviceId(in)
Specifies the communication device to communicate with.
byProgNo(in)
Program number after the change.
Specify as 0 to 15 (0: Program 0, 1: Program 1, and so on).
Return value 0x8080: The change program setting is "terminal"
Explanation
This function changes the active program number.
When specifying the same number as the active program number in byProgNo,
or when an invalid program number is specified, the operation to change the
program is performed (internal memory is cleared, etc.), but the active program
number is not changed.
Supported version 1.00
Format LONG LJV7IF_GetActiveProgram(LONG lDeviceId, BYTE* pbyProgNo);
Parameters
lDeviceId(in)
Specifies the communication device to communicate with.
pbyProgNo(out)
The buffer to receive the active program number.
It is stored as 0 to 15 (0: Program 0, 1: Program 1, and so on).
Return value No individual return code
