I'm wanting to set up a network of 4 315-PN/DP
PLCs.
I will have one PLC that will take the speeds
from the other 3 machines (as words) and display
them on a HMI.
I've no experience with Profinet and would like
to use this method (I could do this with Profibus
but, as a learning exercise, I would like to know
how this could be done in Profinet).
I can configure the machines to have IP
addresses:
Machine 1 - 192.168.0.1
Machine 2 - 192.168.0.2
Machine 3 - 192.168.0.3
Central PLC - 192.168.0.10
I just don't know how I set up which 'words' get
passed along the network and also how I address
the words at the other end?
i.e.
I have set up my Central PLC in the hardware
config but it won't let me then 'hang' other PLCs from the Ethernet link?
Has anyone any idea how I would get one word from each PLC back to the central (or main) PLC ?
Many thanks for any light you can shed on this.
