IOtech GPIB Command Associated MCC GPIB 488.2 Command

Trigger Trigger

Syntax

Trigger {IOtech} INT WINAPI Trigger(DevHandleT devHandle);

Trigger {MCC} Trigger(int board, short address)

Usage Notes

Trigger {IOtech} – IOtech’s Trigger command issued a Group Execute Trigger (GET) bus

command to a specified device. If no interface device was specified, then the GET only

affected a device that was already in the Listen state, as a result of a previous Output or Send

command.

Trigger {

MCC} – This command triggers one device. When this call is executed, the GPIB

GET (Group Execute Trigger) message is sent to the specified device. To trigger several GPIB

devices, use TriggerList.

The following example triggers a device connected to board 0, whose primary GPIB address is

6 and secondary address is 12.

Example: Trigger (0, MakeAddr (6, 12));

1 2 ... 56 57 58 59 60 61 62 63 64
