Can we configure Boolean input channels in NI Veristand?

[RishiDivakar93]

Hi All,

I'm currently using Veristand 2018.While configuring the input/output(not item properties) channels, I have always used numeric data type. However, I have never come across any example programs, specifying the channels as Boolean. Can you please help me understand whether the input/output channels can be configured as Boolean in Veristand 2018?

Hi,

so far VeriStand uses DBL as the only data representation for all channel values. So from the memory economy point of view - Boolean channels do have significant overhead.

The general implementation is to translate booleans into zero or non-zero to go to VeriStand. On the VS Workspace, you can drop down a boolean control or indicator, which will be a 0.0 or 1.0 DBL when written from VS or zero and non-zero when reading from a custom device. When I make custom devices, I just use Not Equal To 0? to translate it to a bool to use in my logic or Boolean to (0,1) to translate to a double to go to VeriStand. It's not terribly efficient, but it's the only way

Ok, but I think we must be able to map the DIO signals as it is, without comparing numeric values. Hope in future versions, this will be taken care of.
