  1. MRP ring status on HMI ??

    Hi I've got a medium sized MRP system and would like to display the same style topology that you see in TIA Portal on a HMI for the operator / engineers, Thanks Dan
  2. Hello all, i'm looking at installing a completely new network for our PLC system, using a ring topology. at the same time i would like to incorporate the IP cameras and VOIP into the same network.  each system is on a different sub net, PLC = x.x.1.x, Cameras= x.x.2.x, VOIP= x.x.3.x estimated camera traffic will be 25 Mbps, PLC 10 Mbps, VOIP no more than 1 Mbps  switches would be capable of 100 Mbps  question: managed or un-managed switches? if it is possible to use un-managed without affecting operations then this would be a massive cost saving    please only comment if you have practical experience implementing this  many thanks Dan
