Hi all,
I'm using DASYLab9 and want to connect a device using the Modbus TCP/IP protocol.
What is the best way setting up communication?
Is there a modbus driver, like the one in DASYlab11, that also supports the TCP/IP interface?
Thanks in advance!

Hi Bram,
DASYLab 9 has a MODBUS RTU module set for analog and digital i/o. It supports serial only, and integer only (signed, unsigned). It does not support different byte orders nor does it support floating point.
TCP/IP was brand new for DASYLab 11.0.1 (the service pack 1), as was the robust support for different data types.
You'll be forced to update to V11 to use it. You can download the evaluation version, if you want to try it out. You'll need to also download the service pack 2 and apply it to activate the Modbus modules.

Thanks for the reply!
So the only solution is an upgrade to version 11?
Is there some kind of workaround for v9, using Icom modules or something?

Bram,
Modbus is a structured format, where both the timing and the package are well defined. You could try ICOMS, but I could not begin to tell you how to decode the package. I rely on Modbus debuggers to look at it, to find the data and decode it. And that's using the Modbus module for communications.
We put a lot of work into enhancing the Modbus module for V11, and we would hope that you would think it worth the price of the upgrade, in addition to the other features and improvements made since you purchased V9.
