Hello, i am using a PID module, for the set point i have to set (display) 2 values of voltages i.e 1.5v for 5psi ang 5v for 15psi, is pre/post trigger module with hyateresis settings suitable for this, if so wat are the settings tht i shld do? is der any other module suitable for this application

To set (create) the Setpoint?

Use a Slider module. 

Or a Coded Switch.

Or Read Global Variable

How to move between the values?  Are you gradually increasing the setpoint? Then you need to configure a generator module to create the appropriate waveform. The best module is the DASYLab Pro Sequence Generator, as you can configure the values, the rate of change, and the exact timing.

For a simple change, from the low value to the high value, use the Data Reduction\Time Slice module. It has two or more inputs (which can be the Sliders, or the Read Variable modules), and will switch between the inputs based on time, outputting the selected input value.

I am gradually increasing the set point, what are the properties settings i should do the sequence generator module, and how to use this module in the worksheet for the setpoint.

Please guide me with the properties settings i need to do for modules i am using for setpoint: global variable read, time slice.

I can't do a tutorial for the sequence generator here - it's a moderately complex module. 

There is an example in the ..\Worksheets\Examples folder :

sequence generator step info.DSB

It shows a two Sinusoidal steps and two ramp type steps. You'll want to use the ramp, so that you can define the absolute start, absolute end, and the duration. Here is a picture of this example and the Sequence Generator Program.

Thanks for the info, its working fine now.
