Hi!
I’m currently learning to program with Siemens S7 300 series plcs.
As part of a project we are to link two 313C CPUs.
What kind of options do we have?
I have read through the main document under communication at the siemens automation support page; http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=20982954&caller=view
What I understand is that we have two options as long as we don’t have a CP card.
This is using the PB S7 basic protocol using the IPUT/IGET or using the PB-DP protocol?
The underlying documentation at the communication folder does not explain the setup for these two protocols…at least not without using a CP card, so I hope you guys can help me out here a bit.
I’m not even sure how to cable up these two into a network. The only network connection the CPU’s have is a MPI plug, so I don’t really understand how these two can be connected using Profibus without buying an additional CP card or something.
That said how, difficult is this task really?
Any useful links etc will be grately appreciated!
