LM Modbus slave Application Note 016

[SigmaTec]

Hi all,

scripting Lua lines to tune my LM (a Wiser For KNX one) in order to make it a Modbus Slave, I use with succes the application note "AN016_spaceLYnk_as_a_Modbus slave_v2.0" from Schneider Electric in Modbus RTU.

Modbus master is an EGX150 Schneider Electric.

So, success is not forthcoming when I try to turn my LM to be a Modbus TCP Slave, as the application note explain it's possible to do.

-- modbus init
if not mb then
--****************************************************
-->>>>>>>>>Modbus slave setting<<<<<<<<<<<<<<<<<<<<<<<
require('luamodbus')
mb = luamodbus.tcp()
-- IP:10.154.12.73, port: 502
mb:open('192.168.1.49', 502)   -- my LM @IP
mb:connect()
-- slave id
mbetslave(10)

../..


All your ideas are welcome !
Thank's in advance.

Remove mb:connect() and use 0.0.0.0 as listening IP: mb:open('0.0.0.0', 502)

Your pourpose :

Remove mb:connect() and use 0.0.0.0 as listening IP: mb:open('0.0.0.0', 502)


Sorry, but it doesn't work for me, only Modbus RTU run correctly (502 port is ok on LM and gateway) :

Note : I use LM as Modbus slave with an EGX150 Schneider Gateway
