Runtime variables of the E115-P
Reading flow rate, total, accumulated total or current day totals: When reading runtime variables, the
given value may differ slightly from the value that is displayed on the display – this is due to the fact
that the display is limited in the number of digits and may have a slower update rate.
When variables are read in integer format, the returned values are given including the decimals. For
example, when two decimals are selected for total and total has a value of 123456,78 the display will
show 23456,78 while communication will read a “total” of 12345678 (note that the decimals should
be adapted according the setting in “total decimals” which is in this case 2).

Commands:
0x0101: Clear grand total
0x0102: Clear total A
0x0104: Clear total B
0x01FF: Clear all total values
* Clearing total: Total can also be cleared by writing the correct command to the total command register, as shown above.
It is also still possible to use the old method: Write a value of 0 to all the 3 registers of total in a single write action.
Writing any other value will result in the reply of an error message.
Note: The runtime variables shown in above list must always be read or written individually, for the indicated number of
registers, in 1 single action!
