R/W INTEG_OPTS is to be used to specify several integration
options as type of input used in each input, flow direction to be
considered in the totalization, status to be considered in the
totalization and if the totalization residue shall be used in the
next batch after a reset.
Uninitialized
The following INTEG_OPTS are possible (see also
INTEG_TYPE):
• Input 1 accumulate: IN_1 is used as pulse (otherwise as rate)
• Input 2 accumulate: IN_2 is used as pulse (otherwise as rate)
• Flow forward: only positive net flow will be taken into
account for totalization
• Flow reverse: only negative net flow will be taken into
account for totalization
• Use Uncertain: IN_1 and IN_2 input will be taken into
account even if their states are "Uncertain" (otherwise the
value with the last "Good" status will be taken)
• Use BAD Input: IN_1 or IN_2 with "Bad" status will be
interpreted as "Good" (Note: only the status is interpreted as
"Good", the value isn't used for totalization, but the good one,
i.e. RTOTAL isn't affected with this setting.
• Carry: integration after a reset starts with the init value, but
with the residual after the trip value.
• Add zero if Bad: if one of the input (IN_1 or IN_2) statuses are
"Bad", not the last "Good" value is used for totalization, but
zero (0).
• Confirm reset: after a manual reset of totalization, the next
manual reset must be preceded by a reset confirmation by
the control system.
• Generate reset event: in case of reset (automatic or manual),
an event notification will be sent to the control system.
(This function is an option and not supported.)
