Siemens Web server OZW772... V8.0 CE1C5701en
Building Technologies Record consumption data 2018-03-15
• The user determines the read time for consumption data file via file
transfer. With daily readings, the user can read the web server value up to
24 hours after the web server reading.
• The consumption data file is sent by e-mail as soon as the consumption
data
is collected.
• Via the chain (1) (3) (5) (6), the current values for WRI982 pulse meters
are
a maximum of 5 hours old plus read delay.
• Via the chain (2) (3) (5) (6), the current values for M-bus meters are a
maximum of 8 hours old plus read delay.
• Via the chain (4) (5) (6), the current values for the pulse meters to Synco
700 controllers feature only the read delay.
The current value timestamp is written as follows to the consumption data file:
• For WRI982 pulse meters: Added up hourly by WRI982.
• For M-bus meters without a manufacturer-specific timestamp: by QAX9…,
at read time QAX9…/WRI982.
• For M-bus meters with a manufacturer-specific timestamp: by the M-bus
meter at the manufacturer-specific time.
• For Synco 700 pulse inputs: By Synco 700 controller, added up every 5
minutes.
Monthly values are transmitted every 24 hours.
The monthly values are transmitted on the third day of the month between 5 am
and 10 pm.
Not all M-bus meters form their own monthly values. If not, the QAX9… assumes
the task.
The Synco 700 controller forms its own monthly value. The reading takes place
on the third day of the month between 5 am and 10 pm.
The OZW772… does not have an S-Mode input for monthly values and therefore
does not provide any. The entry in the consumption data file remains blank.
The due day values of meters connected to the QAX9… are formed on the
centralized due day. The due day for QAX9… is active in the default state (Default
setting of December 31), but can be edited on the QAX9… or via web server (see
Section 2.5.3.6 "Consumption data").
Please note the following, however:
• A temporary due day value is formed during the commissioning of the
QAX9…: This is the start value of the meter using the start value date.
• The first due day value is formed using the due day date if the centralized
due day is reached for the first time.
• Due days that differ from the centralized due day (by the corresponding M-
bus meters) are blocked accordingly.
• A due day value is used for precision only if one M-bus meters supplies a
due day value on the centralized due day.
