Reply on Broadcast
Purpose
Some ModBus libraries don't support Broadcast
unitId=0
over tcp/ip what creates timeout and/or error condition in the tcp client.While
mbusd
is already prepared not to wait for a reply on a Broadcast,mbusd
does not send an answer to the client.Change:
This merge request adds the option
-b
tombusd
startup options andreplyonbroadcast
as config file option to enable the reply on a Broadcast, defaulting toNO REPLY ON BROADCAST
.Updates the
man mbus
andmbusd -h
or usage:Test w pymodbus
Remark: Without the pymodbus.client
broadcast_enable=True
, to simulate libraries that don't have thebroadcast_enable
on a tcp modbus connection.original or new without
-b
mbusd -b
test libmodbus
ModBus version:
3.1.6
original or new without
