Switch Health Center
Starting in 2015, National Instruments released several NI Switch modules with a variety of new advantages. Some of these include Resistive Self-Test, on-module temperature monitoring, use of the Switch Health Center, and installation independent from DAQmx. NI Switch modules with these features are sometimes referred to as "CA4" devices, where modules released before 1/1/2015 are either CA1, CA2, or CA3.Installation Separate from DAQmx When using only these modules, the NI-SWITCH driver can be installed separately from NI-DAQmx . This is done by selecting the Custom install option during installation and has the advantage of a smaller installation size.
The Switch modules released after 1/1/2015 do not include scanning or triggering. This means the new Switch modules will not perform DMM-Switch handshaking functions and cannot be used with scan lists.
Like older modules, the new Switch modules can be simulated though LabVIEW by using niSwitch Initialize With Options.vi from the NI-SWITCH palette. Note that this simulation will not persist between sessions: when the session is closed, the simulated card will be deleted. In addition, the new simulated modules can not currently be created through MAX.
NI Switch Executive
The new Switch modules can be used in Switch Executive but must be added as IVI devices and will not appear automatically when using Switche Executive versions before 15.1. Note that native Switch Executive support was added in Switch Executive version 15.1. Once a topology (found in the NI Switch Help under each device) is added to the IVI session, the device can be programmed using the graphical schematic interface.
