11.1
Connectivity
This function can be used to link control units, connect the control
unit(s) to the Internet or establish a network. To establish the
connection, a data cable must be connected to one of the connections
10 to 12 of the user interface ( Fig. 7, page 10).
11.2
Establishing a network with other control units of the
series Control 8000
A connection can be established between control units via the LAN1
(input) and LAN2 (output) interfaces. To do this, the control units must
be inter-connected using a LAN cable.
▶ Observe the documents of the master control unit.
11.2.1 Establishing a network
The same software version must be used for all control units in systems
containing several control units (cascades control device extension).
The connection between control units must be established via a LAN cable.
▶ Observe chapter 8.1, page 10 for the addressing of the control units.

Explanation
The control unit interfacing is started.
Prompt as to whether the interfacing process should be started or
cancelled.
The connection between the control units is severed.
Prompt as to whether the disconnection process should be
started or cancelled.
Specifies the time in which all control units must report to the
master control unit.
Specifies the time that must elapse before a fault is signalled in
the absence of a transmission protocol.
Matching with an old firmware.
Heat source with master control unit
The heat source with master control unit is the lead boiler (master) and
has the control unit address 0.
▶ Insert LAN cable in the LAN 2 connection ( Fig. 7, [10], page 10).
▶ Set the address switch ( Fig. 7, [5], page 10) to 0.
Heat source with slave control unit, substation (Slave) and
extension control devices
All heat sources with slave control unit are lag boilers (slaves) and have a
control unit address which is > 0.
▶ Plug the LAN cable from the previous control unit into the LAN 1
connection ( Fig. 7, [11], page 10).
▶ Set the address switch ( Fig. 7.4, [5], page 10) to 1.
To integrate further lag boilers:
▶ Establish connection following the same procedure described above.
▶ Set the address switch (Fig. 7, [5], page 10) to 2 or higher.
An address must not exist twice.
▶ Observe chapter 8, page 10.
The LAN 1 connection to the master control unit (address 0) is envisaged
for the Internet connection, or connection to a building services
management system via Modbus TCP/IP, and must be programmed
accordingly. The LAN 1 connection to control units with address > 0 can
only be used for internal communication between control units in the
Control 8000 series. LAN 1 can therefore not be programmed.
As a basic rule, the LAN 2 connection can only be used for internal
communication between control units in the Control 8000 series.
This does not depend on the control unit address that has been set.
