1 General information and technical specifications
1.1 Purpose of use, application area, operation principle
is designed for:
(SAE j1939+S6 Protocol) into the data of RS-485 interface,
with their saving in registers of Modbus RTU Protocol.
is designed for:
Reading registers of Modbus RTU Protocol and conversion of the read data into SPN
(SAE j1939+S6 Protocol), with their output into CAN interface.
Area of application
—
data converters may be employed in
monitoring complicated transport or industrial objects equipped both with CAN-bus, Units of
CAN j1939/S6 Telematics interface
, and devices using RS-485 interface (see figure 1).

Employment of data converters
Operation principle:
The input interface of
MasterCAN CAN2RS
CAN data converter is connected to
the onboard CAN-bus using
(see figure 2). In accordance with the user
settings, the converter selects the required SPN from input messages (
and converts them into data (up to 100 parameters) of RS-485 interface which are entered
into specified registers of Modbus RTU Protocol.
The input interface of RS-485 data converter
—
MasterCAN RS2CAN
is connected to the
respective
(see figure 3). In accordance with the user settings, the
converter reads data from the required Modbus RTU Protocol registers and converts them into
the selected SPN (up to 100 pcs.) which it sends to CAN output interface by means of
S6 Technology.
