Why does my Siemens SIMATIC IOT host monitor flash black?
- GGregory MurphyAug 5, 2025
The host monitor might flash black briefly when inserting the DC connecting terminal because the switch was turned on before connecting the DC connecting terminal. To prevent this, avoid turning the device on or off by plugging or unplugging the DC connecting terminal. Use an external switch to control the device's power.
