RSDLLibsre
This function sets the device to the 'LOCAL' or 'REMOTE' state.
VB format
Function RSDLLibsre (ByVal ud%, ByVal v%, ibsta%, iberr%, ibcntl&) As Integer
C-format
short WINAPI RSDLLibsre( short ud, short v, short far *ibsta, short far *iberr, unsigned long far *ibcntl)
C format (Unix)
short RSDLLibsre( short ud, short v, short *ibsta, short *iberr, unsigned long *ibcntl)
Parameters
ud // Device handle
v // State of device (0 - local or 1 - remote)
Example
RSDLLibsre (ud, 0, ibsta, iberr, ibcntl)
RSDLLibloc
This function temporarily switches the device to the 'LOCAL' state.
VB format
Function RSDLLibloc (ByVal ud%, ibsta%, iberr%, ibcntl&) As Integer
C-format
short WINAPI RSDLLibloc( short ud, short far *ibsta, short far *iberr, unsigned long far *ibcntl)
C format (Unix)
short RSDLLibloc( short ud, short *ibsta, short *iberr, unsigned long *ibcntl)
Parameter
ud // Device handle
Example
RSDLLibloc (ud, ibsta, iberr, ibcntl)
After switchover to LOCAL state, the instrument can be manually operated via the GUI. On the next
access to the instrument by means of one of the functions of the library the instrument is switched again to
the REMOTE state.
RSDLLibeot
This function enables or disables the END message after write operations.
VB format
Function RSDLLibeot (ByVal ud%, ByVal v%, ibsta%, iberr%, ibcntl&) As Integer
C-format
short WINAPI RSDLLibsre( short ud, short v, short far *ibsta, short far *iberr, unsigned long far *ibcntl)
C format (Unix)
short RSDLLibsre( short ud, short v, short *ibsta, short *iberr, unsigned long *ibcntl)
Parameters
ud // Device handle
v // State of END message (0 - no END message or 1 - send END message)
Example
RSDLLibeot (ud, 1, ibsta, iberr, ibcntl)
If the END message is disabled, the data of a command can be sent with several successive calls of write
functions. The END message must be enabled again before sending the last data block.
RSDLLibrsp
This function performs a serial poll and provides the status byte of the device.
VB format
Function RSDLLibrsp(ByVal ud%, spr%, ibsta%, iberr%, ibcntl&) As Integer
C-format
short WINAPI RSDLLibrsp( short ud, char far* spr, short far *ibsta, short far *iberr, unsigned long far *ibcntl)
