IVxiBackplane::AssertUtilSignal

Note: Keysight's VISA COM does not support a COM server for VXI. The IVxi-related interfaces are listed in this help file because they are included in the global VISA COM library.

Description

Asserts the specified utility bus signal.

This operation can be used to assert either the SYSFAIL or SYSRESET utility bus interrupts on the VXIbus backplane. This operation is valid only on FRAMEVXI BACKPLANE and SERVANT (mainframe) and VXI SERV (servant) sessions.

Asserting SYSRESET (also known as HARD RESET in the VXI specification) should be used only when it is necessary to promptly terminate operation of all devices in a VXIbus system. This is a serious action that always affects the entire VXIbus system.

VB Prototype
