CNTMAX] and set a user-preferred value. Note that the user can set the maximum number
from 9 to 2147483647.
(iii) Setting the initial-value
The counter returns to an initial-value when the counter reaches the maximum value;
generally, the initial-value is set to either zero or one (0 or 1); hence, the number is re-counted
from either “0 (or 1)” following the maximum value. If the user wishes to set an alternative
initial number, setting [GCNT01-CNTRV] can be used. Note that the user can select the initial-
value from zero (0) to 999999.

(iv) Setting for the report (Dead band)
The counter-value can be reported to the remote-end; the user can set the report-timing using
the setting [GCNT01-SDB]. For example, if the counter-value is to be reported for every change,
the user should set 0 for the setting [GCNT01-SDB]. When five(5) is set for the [GCNT01-SDB],
reporting is performed when the counter has incremented by six(6) following the previously
reported counter-value.
