SIRe Modbus
This manual describes how to connect SIRe
Advanced with Modbus/RTU via RS485, the
technical specification of the protocol in SIRe,
the parameters and their use.
For more information about other functions
in SIRe, please see the main manual.
For more information about Modbus please
contact your BMS supplier or
www.modbus.org
Connection
Modbus/RTU via RS485, connects on a 3
pole contact on terminal [BUS] on the SIReA1N.
What information is presented
Please see list of parameters.
What information is not presented
Information regarding run times for each
individual unit is stored on the B1-pcb and
can only be viewed locally.
Modbus Information
Supported functions
Function codes 01, 02, 03, 04, 05, 06,
08, 15, and 16 are supported. Diagnostics (08)
supports sub-codes 0, 2, 10, 11, 12, 13, and
14.
PDU length
Maximum PDU length is 256 bytes.
Supported network topology
General 2-wire topology described in
Modbus specifications is supported. Multiple
slaves are supported.
Software supports only RTU mode; ASCII
mode serial transmission is not supported.
Ground level
Internal and external bus shares the
same common ground, the RS-485 signals are
not isolated.
Start and stop bits
One start bit, one stop bit.
Parity
Current software uses only
'None' parity mode.
Broadcast
Broadcast not supported because A1
fails to not to respond broadcast.
Setting values outside valid range
If written values are outside their
allowed range, they will be set to the nearest
value which is in the range.
Bus termination
Bus is not terminated but it has 4.7
kohm pull-up and pull-down resistors.
Registers used
Coils, discrete inputs, and input
registers are supported, but there are no
registers. So the responce is always "Illegal
data address".
Holding register
16 bit integer register R/W

During the function Stages (see main manual) the roomtemp is measured every [set value] minute
If internal temp. Drops below set value during overrun countdown, the fan stops.
Fan overrun countdown after heat has been on. Rounds to nearest multiple of 10.
Reading year copies system clock to internal buffer. All reads and writes are from/to internal buffer.
Writing seconds copies time from internal buffer to system clock.
