Battery consumption while the programmable controller is powered on

Will the battery voltage become low if a programmable controller is powered on all the time?
Category : 

Answer

A battery is consumed regardless of the on/off state of the programmable controller.
Refer to the User's Manual (Hardware Edition) for the module used, and replace the battery periodically.

For example, the life of the FX3U-32BL battery is approximately 5 years (ambient temperature: 25ºC ).
The battery life varies depending on ambient temperatures. Estimate the battery life according to the graph, and replace the battery periodically.
