Web servers OZW772
The OZW772.. web servers (see Data Sheet N5701) allow remote control and
monitoring of plants via the web and smartphone apps.
A total of 4 types of web servers are available, allowing the connection of 1, 4, 16
or 250 Synco 700 devices, RXB/RXL room controllers, RDG/RDF/RDU room
thermostats or Synco living QAX central apartment units.
Functions and characteristics
• Operation via web browser with PC/laptop and smartphone
• Operation via smartphone app (iPhone or Android)
• Visualization of plant via web browser with standard plant diagrams and user-
defined plant web pages
• Types of connection: USB and Ethernet
• Display of fault status messages via web browser
• Sending fault status messages to maximum 4 e-mail recipients
• Sending system reports to e-mail recipients at certain intervals
• Acquisition, display and transmission of consumption data to 2 e-mail recipients
• Function "Energy indicator" monitors data points with regard to energy limit
values, so-called "green limits"
• Web services for external applications via web API (web Application
Programming Interface)
• Encryption with https and e-mail with TLS (Transport Layer Security)
The web servers identify breakdowns and faults of plants or devices plus own
faults (web server faults).
Faults are indicated by the web server’s LED
(with unacknowledged faults,
flashes). After acknowledgement with button
(on the web server) or via the web
or ACS, the LED remains lit as long as the fault is pending.
Fault status messages can be forwarded as e-mails to maximum 4 e-mail
recipients and/or via provider to SMS recipients. Each recipient’s fault priority can
be selected (Urgent/All).
The web servers generate system reports (operating state of plants and devices)
and send these to e-mail recipients at certain intervals. Transmit time (hh:mm),
transmit cycle interval (1...255 days) and priority (Urgent/Nonurgent) can be
selected.
The last 500 events concerning faults, fault status messages and system reports
are stored in the web server (circular memory).
The web servers have a system clock with selectable time zone and summer-
/wintertime changeover. As clock time masters they can send the preset system
time (date and time of day) to the KNX devices (clock time slaves).
The web servers are compatible with the ACS790 service and operating software.
Each OZW772 web server provides function "Consumption data acquisition". For
information about consumption data acquisition, refer to chapter "Synco living".
