PLC vs DCS – What solution to choose? When we want to integrate several software applications, use advanced control algorithms and have future expansion plans, the PLC / SCADA solution may not be adequate. Currently the differences between both solutions have decreased, but they are still important, especially in systems with more than 500 I …
