Hello everybody We are on the phase on making a new plant,I am attaching here the automation network layout of the plant. My concerns: 1-which is better ,connecting the 2 servers on a ring network with the S7-400 PLCs as shown on the layout ,or connecting the 2 servers and the PLCs on a star topology?I mean in terms of reliability,stability. 2-is the place of the engineering station is correct on the network?...I beleive that it has to be on the ring network. Thank you Attachmentnetwork.pdf (419 Downloads) |
