Hello everyone! The Siemens PLC power supply is indicating an amber battery light. If we don't replace the batteries right away, could we potentially lose the program when shutting down the PLC for 10 to 20 minutes? Your assistance is greatly appreciated. Thank you.
If you shut off the power suddenly, you risk losing any data saved in the RAM of your CPU. It is important to power down properly before replacing the battery. These batteries are readily available online, with many users finding them on Amazon.
The Programmable Logic Controller (PLC) experienced three reboots, each lasting approximately 10 minutes. Thankfully, the program was not lost during these reboots. The batteries were replaced, but even after the replacement, the battery light continued to glow red when the batteries were removed. However, after rebooting the PLC, the battery light turned off. Is the amber light just a warning before it turns red? Your assistance is greatly appreciated. Thank you.
Rob mentioned the importance of avoiding shutting off the power abruptly to prevent losing any data stored in the CPU's RAM. It is recommended to change the battery without powering down the device. Replacement batteries are readily available, and can even be purchased from online retailers like Amazon. Your assistance is greatly appreciated.
Absolutely, an amber battery light could indicate a low power situation. If you shut down the PLC under this condition without replacing the batteries first, there's a high possibility of losing your programming data, considering the battery is responsible for backing up the memory. It's always safer to replace the batteries as soon as possible to prevent unanticipated data loss.
