HMI / SCADA (phase 5)

Phase 5: Selection of HMI In this article we discuss the selection of the HMI / SCADA (index of design phases). 5-Selection of HMI or SCADA In medium or large systems, normally the operator interface is defined in the technical specification. If it is a PLC system we will talk about a SCADA, if it […]

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

Select the PLC modules

Select the PLC modules The first step in selecting the PLC modules is to analyze the technical requirements of the application. In most cases this analysis will guide us in selecting the PLC and the I/Os. The next step will be to do different considerations that affect the total cost of the automation solution. In
