IBSAD
Assigns/unassigns a secondary address to a board or device.
Syntax
C ibsad (int boarddev, int address)
Parameters
boarddev is an integer containing device or board handle.
address represents the secondary address. If address = 0 or address = 7F hex, secondary
addressing is disabled. If address is a legal secondary address (60 to 7E hex), the new
secondary address is temporarily assigned to the board/device. The new secondary address is
used until it is either redefined by calling
ibsad again, the device/board is re-initialized by
calling ibfind or ibonl , or the program is restarted.
Returns
ibsta will contain a 16-bit status word as described in Appendix B, IBSTA .
iberr will contain an error code, if an error occurs. Contains the previously assigned
secondary address if no error occurs.
Usage Notes
See also ibpad .
Example
This example assigns the secondary address 7 (MSA7, hex 67) to a device at PAD 5.
C int dev5;
dev5 = ibdev (0,5,0,13,1,0);
ibsad (dev5, 0x67);
