2.8 BUS Interface – BI-100 (optional)
Figure 13
The BI-100 is an optional BUS interface.
The BI-100 supports 32 virtual ventilation buttons that can be
assigned to the individual MR120 modules as ventilation
sources using SIMON LINK. These virtual ventilation buttons
can be controlled via the external bus.Ventilation commands
like OPEN, CLOSE, STOP and OPEN with programmable
time limit can be executed.
The module also has two digital inputs that can be evaluated
through the external bus.
In addition, the BI-100 provides an overview of the entire
system. Detailed states of individual modules can be queried.
The optional watchdog enables the monitoring of the
communication flow and in the event of a bus communication
failure, it can also stop the ventilation function and report a
fault.
The BI-100 has the following additional visual indicators:
• green LED (next to the BUS terminal block)
• yellow LED – “Failure”
• green LED – “OK”
2.8.1 MODBUS
The BI-100 provides an EIA-485 RTU-MODBUS
TP interface (TP = twisted pair) and SG / A / B
terminals (SG = signal ground). The communica-
tion speed is adjustable from 300 bps to 57600 bps. It is also
possible to set the parity, stop bits and a watchdog function.
If the MODBUS communication is lost, the BI-100 goes into
fault mode.
2.8.2 Digital inputs
There are 2 digital inputs. A 24 V DC terminal
(mains) is available to connect the inputs.
Central ventilation commands (e.g. time control
signals etc.) can be connected to the digital input of the
BI-100. These are shown in the connection plan according to
customer requirements. Should you require any changes,
please contact our technical sales department.

ATTENTION
To add a BI-100, hardware and software versions of the
controller have to be synchronised. For further informa-
tion, please contact our technical sales department and
keep the serial number of the control system at hand!
