7.2 Preset and apply start values for energy and overflow counters
At the beginning of a new work order, it may be useful to start the energy and overflow
counter with new start values.
Define the new start values for the energy and overflow counter in data record DS 143.
Note
Pre-set start values for counters
If you have not yet transferred any start values to the CPU using the data record DS 143,
then start the counters with the value 0.
With all the module versions there are two ways of applying the start values:
● Transfer start values from data record DS 143 and apply them immediately
● Transfer start values from data record DS 143 and only apply them after setting a special
bit (DQ bit for counter reset)
Both options are described in the following sections.
General reset
With module versions with 20 bytes of output data you can reset the energy and overflow
counters. With a general reset, you cannot preset any start values; the start values for
energy and overflow counters are always zero with a general reset.
You can find additional information on the general reset in the section Basics for reading
measured values (Page 41).
