I'm afraid that is impossible to do without the technical documentation.
https://www.kepware.com/getattachment/4554c39b-f0e8-41cc-b5f2-7906f8b93db4/mettler-toledo-serial-manual.pdf is a good start, but not enough. It only shows HOW to communicate, not what to ask and what answers will be provided in what format.
Hi, I'm a newbie and I have a Mettler Toledo IND310 scale that I've been told that MT won't provide any technical support for any longer. I do not wish to spend $AUD7,800 on new scales/software therefore I'm wondering what my options are to get the information (dates, times, weights etc) from the scale to a pc (and eventually to excel) - I imagine via RS232. To make things more complicated, I'd like the information from the my pc at the scale to be reflected in a pc located 100m away from the scale. There is wifi at both ends. Or should I be looking to somehow transfer the scale data on to a website so that I can access it remotely? Can anyone please just give me basic ideas for me to take further. I'm willing to take months to teach myself how to do this rather than pay thousands of dollars to a company that shows no support other than "please buy our new product for thousands of dollars".
