I need some help in connecting the mass balance (electronic) to the LABVIEW 8.0. Please help.

[Dennis_Knutson]

Exactly what kind of help? The physical connection?

[Subhayan]

I have a Denver Instrument electronic mass balance. I have connected the balance to a computer having Labview 8.0 through the RS 232 connection. I developed a block diagram where i communicate with the instrument using VISA. I entered the name of the COM Port and set R/W VISA for Reading the mass balance data in the computer. But now when I run the .vi file I get time out error. Can u please provide me a VI.

My questions:

Am i going wrong in the physical connection or is there some logical error.

First you need to read the denver manual 😉 and look how the communication needs to be set up.

1. Correct RS232 initialization (baudrate, start stop bits, parity, handshaking)

2. How and when does the balance send values? Do you need to ask for it?

It's like human communication 😉 some will talk all the time , some you have to kick to get one answer, and not to forget: hopefully you understand the language (number format) they are using 😉

RS232 is a very old protocol, don't expect the plug and pray play  like USB. However have you searched the intrument drivers ? Or asked Denver Instruments for a LabVIEW driver?
