In the previous issue, we outlined the common industrial control devices and software systems in Industrial Control Systems (ICS). Today, we will explore the communication protocols between devices and software systems. Before we begin, let’s first understand the topological access relationship between control devices and software: refer to the hierarchical model division of IEC62264-1: L4 … Read more
The Charm of MES and Industrial IoT (IIoT) Integration Begins to Emerge On the grand stage of industrial production, MES (Manufacturing Execution System) and Industrial IoT (IIoT) shine like two brilliant stars. MES focuses on the management and execution of production processes, while Industrial IoT excels in equipment connectivity and data collection. What wonderful reactions … Read more
Introduction You might not imagine how a semiconductor wafer manufacturing factory, covering hundreds of thousands of square meters and costing billions of dollars, operates efficiently. There are no commanders shouting orders, nor is there manual precision in scheduling each wafer. So, who is silently orchestrating hundreds of precision devices behind the scenes, ensuring that thousands … Read more
Upper machine software for uploading Siemens PLC data to MES This software provides functionality to read data from the Siemens PLC memory, call the API interface provided by MES, and synchronize the data to MES. It can also write data returned from MES back into the Siemens PLC memory. First, let’s discuss reading data from … Read more
Last time we discussed that PLC is the brain of the workshop, today we must clarify its genealogy! Let us grandly introduce its two noble relatives—DCS (Distributed Control System) and MES (Manufacturing Execution System)! (Pulls out the industrial version of the “Family Ethics Drama” script) 🎭 If the factory were a version of “Empresses in … Read more
