What are the maximum energy consumption values for Energy meters and Energy Managers/ E-controllers?

FAQ #101899

Where is the counting limit for Energy meters and Energy Managers/ E-controllers?

What happens when they reach the limit?

 

The maximum energy consumption value for all counters is 9’999’999.
When a counter reaches this value, it will start counting with 0.

In the Energy Manager and in the E-Controller, the
energy consumption value is handled in the firmware.
In runtime, the firmware detects only negative values.
A lower positive value is only detected during a reboot.
In this case, a counter change message appears.
Now you have two possibilities:
1:
You can do a manually reset of the counter value to 0.
That means you have to reject the proposed action on the user interface of the device. 
=> A new file is created with a higher index by the firmware.
The history bar charts are lost and the visualization starts to redraw from the current day.

2:
The second possibility is to accept the appeared proposal from firmware.
=> The history bar charts stays, but the values on the counter and on the user interface aren’t the same anymore.

Anyway the firmware counts internally with floating point values.
