Need an inexpensive data logger to grab 10 registers in 8 devices communicating over modbus tcp (ethernet)

I have 8 weigh scales that communicate over Modbus TCP ( Ethernet ) and I need to track their values and store it on a PC.

I don't want to have to spend $1,200 for a scada package and I don't want to have to program anything. I could spend up to $500.

Any ideas out there?
Thanks for your help.

I found something on modicon's technical website that will definately help.

eclipse.modicon.com

Simple Modbus TCP Logger for $300.00

I am downloading the demo version now.

Hope this helps.
 
WOW! You rarely see tools like these. A simple and elegant engineers tool for DAQ that does not cost an arm and a leg. Great find. Thanks...

Sounds like a job for the MatPLC. (Disclaimer: I'm one of the developers.)

You'd use the Modbus module and the Data Logger module, configure them to take readings and log them at the appropriate intervals, and that's it.

Hmm, those manual pages need a lot of work. Please e-mail the MatPLC mailing list for help - we'll help you, and then copy our e-mails into
the manual. :)

Thanks Chrometool.

With the azeo product don't I still have to buy an OPC server. I was a little confused on their site.

I saw the $69 version but thought I would still have to pay $700 for the OPC server to talk Modbus Ethernet?

Thanks
