Watlow F4 Driver Help

[k_jonas]

Hello, 

I am attempting to use the Watlow Driver in LabVIEW. However, I am having some difficulty understanding some of the vi. I was wondering if anyone could explain what the "Unit Address" and "ID Query" is (located in the WTF4 Initialise vi). 

Thank you!

Well without having the VI in question to look at I can only guess but...

The unit address may be needed for multiple devices on the same bus like an IP address or MODBUS unit ID.

ID Query is very common for initialize VI's, it does exactly what it says. it query's the device for its ID.

For example the IEEE common command *IDN? is an ID query that all IEEE 488.2 compliant devices respond to by returning the manufacturer, model number, and maybe serial number and firmware version of the device.

Thanks for the reply.

I am new to LabVIEW and am missing a lot of the general knowledge. I have attached images of the front panel and block diagram if you would like to see.

I am assuming I would put "1" for the Unit Address as I am only connecting a single device. 

Thanks

Unit address is start from '0' but actually you have to match it with setting inside the watlow.
