Central communication
unit
with integrated web server function
The central communication unit OZW775 in plants is used together with Synco
700 devices, RXB/RXL room controllers and the Synco
unit. Key features:
• Remotely operate and monitor up to 250 Synco devices in a KNX network via
ACS software and/or via web browser.
• Link to an operator station (PC/laptop with ACS) via direct connection (USB)
or telephony (RS-232 modem).
• Link to a web browser via Ethernet (Ethernet card OZZ7E5 required) and/or
via direct connection or telephony.
• Customizable user profiles for web operation.
• Customizable user texts for inputs, outputs, function blocks.
• Send fault status messages to operator stations, SMS recipients,
pagers, fax machines, e-mail recipients (message receivers).
• Periodically send system reports to message receivers.
• Storage of the last 500 faults and messages (history).
• 4 message receivers with configurable receiver types and
transmission times.
• 8 digital inputs for fault and operational status contacts.
• 8 universal inputs, configurable for analog, digital and pulse signals.
• 5 runtime totalizer meters, automatically send service alarms.
• 8 meters for pulse signals from heat, water, gas or electricity meters.
• 4 seven-day time switches to switch consumers via relays.
• 6 relays for use with 7-day time switches or as fault relays.
• 5 offline trends with 50,000 recorded values.

Page 6: Universal Inputs
Technical design The central communication unit contains various function blocks (FB). The functionality of the unit can be extended by connecting (binding) the digital inputs N.D1…N.D8 and the universal inputs N.X1…N.X8 to the FB inputs "d", "x", and "i" (see figure and function block description). - Page 7 Function blocks FB "Faults" FB "Faults" is designed for 20 fault inputs. Inputs N.D1…N.D8 (digital) and N.X1…N.X8 (digital/analog) are connected to FB inputs "x". "Relay 1" and/or "Relay 2" is activated depending on fault priority and source. FB "Faults" handles faults and failures of the Synco devices (“System“ faults) listed in the device list as well as faults at the fault inputs and faults of the central communication unit ("Local"...
