Wildeboer-Net
System properties and benefits
Properties
•
A subnet controller is used to set up to four subnets which can each be up to 3200 m in length.
•
Up to 32 field modules can be connected per subnet. They are detected and addressed automatically.
•
A total of up to 32 subnet controllers can be included in a single Wildeboer-Net. The subnet controllers contain the
2-way switches required for connection.
•
If more Ethernet connections are required, a switch needs to be planned for on site.
•
A length of 100 m for the data cable between modules is permitted.
•
Galvanically isolated partial segments between modules.
•
Faults on the field modules or interruptions and short circuits on the galvanically isolated partial segments of a
subnet can be localised, rest bus operation is then performed. Once the fault has been eliminated, communication
as a whole is continued.
•
"Management level" cable recommendation : min. CAT 5
•
"Field level" cable recommendation
: CAN-BUS, shielded 120 Ω twisted pair cable,1 x 2 x 0.34 mm²
•
The Wildeboer-Net software required for visualisation of status and diagnostics data and for configuration and
programming is contained in the central operating unit, or can be installed on the user's PC.
•
A permanent connection to the central operating unit or the user's PC is not required for operation of the system.
•
Gateways for BACnet, Modbus, LON, KNX or OPC-DA are available for connection of building control systems.
Alternatively, data can be forwarded via an OPC-UA server.
•
The connected periphery is supplied with 24 V DC of power from the motor, IO and volume flow and pressure
controller modules.
•
Field modules and subnet controllers
- permanently store data, even in the event of a power failure.
- in the plastic housing 250 mm x 110 mm x 85 mm (L x B x H). Protection class II, protection rating IP40.
- with T2.5 A microfuse which can be replaced from the front.
- with standard Europlug and 1.5 m connecting line for direct connection to an on-site 230 V AC sock-
et. Alternatively, the standard Europlug on the module can be removed for a permanent connection.
Fuse protection for up to 10 modules with a category C, 16 A circuit breaker.
- with LEDs for displaying operational data.
- with push button for manual operation of the basic functions.
- Real-time clock with leap year adjustment and daylight saving/standard time switching. Initial charge time of
the buffer capacitor 30 minutes, discharge time 31 days.
Benefits
•
Reduction of the fire load thanks to field bus technology.
•
Voltage drops on the lines between field modules are ruled out, additional power units not required.
•
Long cable length 4 x 3200 m per subnet controller thanks to galvanically isolated partial segments.
•
Quick commissioning with automatic addressing of the field modules.
•
Simple system upgrade.
•
Automatic restoration of the system after module replacement.
•
Partial commissioning is possible.
•
User-friendly operating interface with comprehensive functions.
•
Simple parametrisation, no programming.
•
Quick fault diagnosis in case of module failure and bus malfunctions.
•
Simple implementation of building code control requirements for ventilation and air conditioning systems.
