1. What are the differences in electromagnetic compatibility between different brands and models of PLCs?
»»» Differences in electromagnetic compatibility between different brands and models of PLCs mainly stem from design standards, component selection, and protection levels. Specific differences and selection principles are as follows:
· Core manifestations of EMC differences:
o Immunity levels: For example, Siemens S7-1200 series electrostatic discharge immunity reaches ±8kV (contact discharge), while some domestic entry-level PLCs only ±4kV; Schneider M3...

1. What impact does high-power equipment (such as cranes, welding machines, etc.) in industrial production workshops have on the electromagnetic compatibility of PLC industrial control immunity? How to protect against it?
Answer: High-power equipment (welding machines, cranes, etc.) interfere with PLCs through both conduction and radiation paths. Specific impacts and protections are as follows:
Main impacts:

  Power interference: Voltage dips (e.g., crane startup causing 10%~30% voltage drop) or spikes (welding machine arc ignition generating kV-level spikes) during equipment start/stop, causing PLC power module overload and CPU reset
Radiation interference...

Global semiconductor market continues recovery. IDC predicts that the global semiconductor market size will reach $697 billion in 2025, a year-on-year increase of 11%, with the foundry market growing 18% to $298 billion.
