Hellow,
I would like to build a MODBUS TCP connection between a Siemens CP443-1 (or a Siemens CP343-1) card and Visual Basic Application on Microsoft Excel. Probably reading data to Excel VBA would be the complex part of the problem. Thereout I would be a step forward if someone help me to get ModBus addresses from Siemens.
I know that you have to purchase blocks if you’re working in S7. If you want a ModBus TCP connection via CPU you’ve to apply the following package from Siemens ‘2XV9 450-1MB02’. Do you want to communicate via CP card you should use the '2XV9 450-1MB00' package.
If you switch to TIA Portal then these blocks are automatically integrated. This is also the reason why I’m using TIA Portal. I find nowhere a detailed manual where you get an explanation how to work out the ModBus TCP communication via CP card (443-1 or 343-1) using TIA Portal.
It would pleasure me, if someone can solve my problem.
Grt, YELO
