“The opposite of isolation is networking and networking requires networkers!”
However, the OT network level, where the majority of data for higher-level ERP/MES applications is generated, is dominated by PLC experts which only feel comfortable in isolation. In terms of network technology, the OT level therefore lie across (in the stomach) to the higher level IIT/Scada and IT networks. The IIT/Scada network has to put a lot of effort into trying to compensate this disadvantage for the lack of network connectivity. At a real project with 22 PLC’s and a superimposed IIT/Scada network is shown avoidable unnecessary costs in the rage of 100,000 Euro.
