In the industrial area there is a choice of controller technologies with different characteristics, which makes this form of intercommunication and interoperability difficult, due to this OPCUA technology has been proposed as an alternative that allows intercommunication between controllers from different manufacturers. The objective of this work is to analyze the use of this technology for the intercommunication of industrial controllers with different communication protocols through the analysis of case studies with different characteristics regarding security, encryption and digital signature. The results showed that the use of the OPC-UA communication system reduced the configuration complexities as it supported open systems, tolerated firewalls and configuration. Allowing the immediate validation of variables from the SCADA system to the industrial controllers without prior configuration. With this it can be concluded that the OPC-UA communication can successfully replace the traditional OPC system.
