De-Multiplexer Mode
In this mode of use the SGW1-IA3-MMP has the ability to establish communication between
a master and several slaves with different characteristics, such as Modbus type, parity, baud
rate, etc. To do this you must configure each port of the device with the particular
characteristics of each slave.
Example of configuration: 1 Master and 3 Slaves (with different characteristics in their series
ports).
The first command to use is
MSCOM
and set Port A in "Master" mode and the other Ports in
"Slaves" mode”.
In order for the device to know which port to send the Modbus query sent by the master, the
Modbus ID range of the slave devices of each port must be configured. Use the
SRANGEADD
,
SRANGEDEL
, and
SRANGELIST
commands
With the
BAUD,BITS,PARITY,STOP
and
PROTOCOL
commands you can configure
the particular characteristics of each port. The team will perform conversions between one
COM and another if necessary.
