Caution!
You are handling dangerous
electrical current!
Disconnect the supply voltage before making any wiring
modifications.
Ensure that the system cannot be switched on accidentally.
Ensure that the device and its surroundings are potential free.
Please refer to the specific installation and mounting instructions.
Qualified personal only should handle the device.
The device has to be mounted in such a way that no unintentional
operation may occur.
All control and supply voltage wiring must be routed so that no
inductive or capacitive interference or any other severe electrical
noise disturbance may interfere with the device.
Supply voltage variation must not exceed the specifications in the
technical details. If so, proper performance of the device cannot be
guaranteed.
Emergency installations according to EN60204/IEC204 (VDE0113)
must remain active in all modes of the automated installation.
Activation of the emergency installation must not cause an
uncontrolled or undefined start cycle.
The software engineer has to make sure, that no failure functions
of the automated installation may occur when line faults or core
faults arise.
Notwithstanding the above, local regulations must be observed in
all installations.

Safety-related advice
Danger to life through electrical current!
Only skilled personal trained in electro-engineering should perform
the described steps in the following chapters. Please observe the
country specific rules and standards for the mini module
installation. Do not perform any electrical work while the device is
connected to power!
Please pay attention to the following rules:
Activate the automated installation
Disable any automatic restart system.
Electrically isolate the installation
Cover any non-isolated areas

Introduction
Since the data from SLS-500-MBUS-MODBUS Converters can be
read from any Modbus-Master (automated control, visualisation
system etc...) a very broad range of applications becomes
possible. For instance data from a heat meter can be easily
represented on a mimic display. Each MBUSMODBUS Converter
module can read the data from up to 8 Meter bus unit loads ( 1 unit
load corresponds to 1,5 mA current consumption of one
participant). Thus maximal 8 devices each one unit load can be
connected to one MBUS-MODBUS Converter. The current
consumption of a device can be seen from the respective data
sheet.
The data to be read are freely configurable and are automatically
actualised in selectable periods of time.
•meter-Bus ports for max. 8 unit loads (1,5 mA)
•meter-Bus interface: 300 to 38400 bps, 8 data bits, even
parity, 1 stop bit
•meter-Bus and Modbus interfaces are galvanically isolated
•Modbus interface: RS232 or RS485, 9600 to 57600 bps, 8
data bits, no parity, 1 stop bit
•Modbus address and enquiry interval selectable
•Configuration of max. 100 Meter-Bus values
•4 different data formats for the representation of the values in
the modbus registers
•supply voltage 24 V DC

Description of the
functions
The SLS-500-MBUS-MODBUS converter automatically reads
preconfigured values from MBUS meters and makes them
available in Modbus holding registers. Up to 100 values can be
read via Modbus.
On application of the supply voltage the converter verifies if a valid
configuration is available or not. If so, the converter starts to
initialise all MBUS meters. If no answer is received from an MBUS
device within three consecutively initialising attempts it is skipped
and the next meter is initialised. The initialising procedure is
repeated every 5 query cycles. After a pause of 5 seconds the first
query cycle begins.
The values of all initialised devices are read and depending on the
configuration written into the respective Modbus registers. From
now on the selectable pause time between two query cycles is
activated.
If no answer is received from an initialised MBUS device within
three consecutively reading attempts, this device is reinitialised
within the following working cycle. After three failed initialising
attempts, another attempt follows every 5 cycles. After successful
initialisation the data are read in the following cycle.
Most of the MBUS slaves actualise their values only after a query
has been performed. As the converter allows the definition of
pauses between queries to up to 18 hours, the following
mechanism avoids that ‘old’ values are read:
If pauses between queries are longer that 30 seconds, the
converter requests all slaves 30 seconds before the real query to
actualise their values.
For communication via Modbus the following functions are
available:
•READ HOLDING REGISTER (function code: 3)

•PRESET SINGLE REGISTER (function code: 6)
•PRESET MULTIPLE REGISTERS (function code: 16)
Note: The functions READ HOLDING REGISTER and PRESET
MULTIPLE REGISTERS are limited to max. 50 register per query!
