C.2 RUNTIME VARIABLES OF THE UNIT
When reading runtime variables, the given value may differ slightly from the value that is displayed
on the display – this is because 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 to the setting in “total decimals”, in this case 2).

[h] 0x1220 44641 Total command
register 1 R/W uint16 Commands:
0x0101 (257): Clear grand total
0x0102 (258): Clear total A
0x0104 (260): Clear total B
0x01FF (511): Clear all total values
* Clearing total: Total can 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!
