Drilling down below level 2 of the Purdue model entails understanding theOT-specific protocol behaviors that regulate communication to PLCs or RTUs.
As needs grew to monitor and control more devices in the plant, the PLCs were distributed and the systems became more intelligent and smaller in size.
However, it is not uncommon for them to spend many hours on communication and troubleshooting programming when using communication modules orsmall PLCs.
But it also occurs in more mundane fields,for instance automation technologies such as VSDs, PLCs and HMIs are increasingly built into consumer products.
Interfacing PLCs(programmable logic controllers) to HMIs(human machine interfaces) is a fairly common form of integration work, as is interfacing PLCs to field measurement devices.
In fact, with the era of automation where the SCADA and the PLCs are used in most industrial processes, it must give room for being incorporated in such systems.
