This paper is focused on Analysis of data throughout in communication between PLCs and HMI/SCADA systems. The first part of paper discusses basic problematic communication between PLC and HMI systems. Next part is about specific types of communications PLC - HMI requests. For those cases paper is talking about response and data throughput1-3 . Subsequent section of this article contains practical parts with various data exchanges between PLC Siemens and HMI. The possibilities of communication that are described in this article are focused on using OPC server for visualization software, custom HMI system and own application created by using .NET with Technology. The last part of this article contains some communication solutions.
