Communicating pc with weighting scale (SAG105 METTLER TOLEDO) using VB

Hi,

I had a look on the internet about coding SAG105 weighting scale, but haven't managed to find a code that I can understand. I would really appreciate if someone can guide me to a link or provide me some information on how I can code in VB to communicated with the weighting scales. I just need simple instructions such as: set to 0, read weight value.

Thank you very much in advance

Google implied that this link was for SAG105 but I don't see a reference in the document :

Pretty much anything you want to know ...
send "T<CrLf>" to tare (zero) the reading
send "S<CrLf>" to have the unit Send the next stable reading.

I've seen some mettler toledo equipment comes with and ethernet/ip module.
So installing one of this module is all you need.

I had a read of the document, I see it doesn't mention anything about coding the device in VB, just about EPSON.

The problem here is that, for my project a weighting scale was required and there was one lying around unused. However, the weight values were manually entered so no programming was used and also the documentations for the scale has been misplaced somewhere. So at the moment I only have the weighting scale and nothing else.

I had even looked at the company website here http://au.mt.com/au/en/home/phased_out_products/others/SAG105_1.tabs.documents.html, they still sell the product but don't provide the documentation for coding. Even sent a message to them, it's been a while still no reply.

Are there no template out there?

Thank you for the help in advance

Here is the manual for the protocol.

Use HyperTerminal or Hype Terminal for the connection to the scale first to verify communication.

Once you know the cable, and communications can be made then start your VB coding.

Hope this helps,

Well, no, it certainly doesn't specifically mention coding in VB.
I figured you could figure it out or at least get a starting point so we could help you.
It doesn't matter if you code it in VB, C, C++, Java or whatever, it's serial communication. As Gary mentioned, use a terminal program to work things out, then you'll be on your way to making it work via VB.

Thank you for the help. I will certainly try this out and will update you on how it's going.

I will use Garry's suggestion to check for the connection and than I will start coding in VB.

I had the company regarding the coding aspect however they were unable to provide the coding aspect. Still researching, but so far no luck.

The documents you provided helps me to understand the commands aspect so thank you very much gclshortt.

I hope can find something.
