Communication with Eurotherm software?

Does anyone know if it is possible to communicate with/call the iTools software from Eurotherm from a LV-VI? Or should I use one of the freeware VI's to communicate with the regulator? I want to control 4 heaters from LV.

The better solution is to talk to the controller directly. The interface is very straight forward and easy to program. A couple years ago I had to interface to a large Eurotherm chamber and the interface was a snap.

As I recall there are two suported protocols. Modbus and something called BiSync. Modbus is far easier to use. There are a bunch of places online where you can get LV Modbus drivers (includign as I recall the Eurotherm website).

On info labview a whole list of places for getting modbus drivers was listed:

Don't worry, you don't have to reinvent the wheel.
If you want to buy a supported product, take a look at BusVIEW on
1) http://www.softwarewithrelish.com/tables/productTable.html
There is also an other option at
2) http://www.cardiac.no/English/Products/Modbus-Link/ModbusLink.asp
A third option is found at
3) http://www.vimarket.com/productpage.php3?product_id=180
There's also supposed to be one at
4) http://www.softwarewithrelish.com/

There is one you can download for free (written in LV 4) at
5) http://www.info-labview.org/the-archives/vi/lv4/
,check out the modbus.txt and the modbus.zip

You can also download one for free (I think) at
6) http://www.air.nl/files/modbus.zip

I've been working on projects that has used both 1) and 5),
and they both did the job, after some hacking.
Good luck.

These should give you some place to get drivers--plus I could send you the ones I use. Beyond this, start digging into the documentation on the controller to familiarize yourself with the interface.

So you're suggesting to use another set of modbus drivers (as opposed to the suggest EuroMBUS from Eurotherm)? Did you still use DataSocket to connect to an OPC server supplied with these other drivers?

I'm trying to communicate with a 2408 temp controller and thought I was stuck with having to purchase thier iTools package before I could establish communication with any kind of ease (using LV 6i).

I'm curious, what drivers are you using? What LV VI's are you using to perform your comm?

Thanks!

All I'm saying is that you don't HAVE to use their drivers. If you have them and they work, great. If not there are a lot of options available to you. If you do use their drivers test them carefully as some drivers I got from them a few years ago were very buggy.

There is also no need for playing with OPC, DataSockets or any of the rest. All you need is a serial port and a set of drivers that know how to talk Modbus--which by the way isn't a very complicated protocol. In fact, I once wrote a set of drivers myself just for the practice.

Are you using datasocket? What "interface" are you using?

Thanks,
