6.3 Communication > Virtual interfaces
The MPC-143 can perform as communication gateway Modbus server/client and datalogger
simultaneously. In order to set up these options, different virtual interfaces are needed as
shown below

o
"COM Client". It is needed to configure a COM Client every time a
“transparent” communication mode or M-Bus compatibility is needed. This
is mandatory in order to read devices not compatible with Modbus
RTU/TCP protocols. Configuration parameters are:
o
"Enable": Do not enable any COM client if not needed.
o
"UART": Select the UART number in which a COM Client will be
configured.
NOTE: Once a given UART is selected to be a COM client, it
cannot be used with any other configuration such as Modbus
client/server.
o
"Stack depth": number of parallel executions that can be done in
parallel by the COM client.
o
“Timeout”: it defines the amount of milliseconds defined as time out.
o
"Number of repeats": number of retries defined in case of
transmission error.
NOTE: COM Client must always be used when peripheral devices
connected to a given UART use protocols such as M-Bus, IEC-102, DLMS,
etc.
NOTE: After configuration is completed, click on "
Set " button in order to
save changes.
