TriggerList

Triggers multiple GPIB devices

Syntax

C void TriggerList(int board, int addresslist[])

Parameters

board is an integer which identifies the GPIB board to be used for this operation. In most

applications, this value is 0.

addresslist is an array of GPIB addresses, terminated by the value NOADDR. These

addresses identify the devices to be triggered. If this array contains only

NOADDR, all

previously addressed listeners are triggered.

Returns

ibsta will contain a 16-bit status word as described in Appendix B, IBSTA.

iberr will contain an error code, if an error occurred.

Usage Notes

Use Trigger to trigger only one device.

Example

This example triggers two devices simultanously. The devices are connected to board 0 and

are at GPIB addresses 6 and 7.

C short addresslist[3] = {6, 7, NOADDR};

TriggerList(0, addresslist);
