HomeLynk as Modbus TCP/IP slave

[Mirco]

I have a problem with the script..
I have 2 LM:
LM1 is the one with this script https://openrb.com/lm-as-modbus-tcp-slave
LM2 is the one that need to read LM1

When I try to read with LM1 my LM2, LM2 return tis error:  LM (TCP 192.168.1.91:502) read failed: Illegal data address

The profile in LM2 is this:

Code:

{ "manufacturer":"LM", "description":"LM", "mapping":[ {"name":"Reg1", "bus_datatype": "int16", "datatype": "uint16", "type": "register", "address": 0, "writable": true}, {"name":"Reg2", "bus_datatype": "int16", "datatype": "uint16", "type": "register", "address": 1, "writable": true}, {"name":"Reg3", "bus_datatype": "int16", "datatype": "uint16", "type": "register", "address": 2, "writable": true}, {"name":"Reg4", "bus_datatype": "int16", "datatype": "uint16", "type": "register", "address": 3, "writable": true}, {"name":"Reg5", "bus_datatype": "int16", "datatype": "uint16", "type": "register", "address": 4, "writable": true}, {"name":"Reg6", "bus_datatype": "int16", "datatype": "uint16", "type": "register", "address": 5, "writable": true}, {"name":"Reg7", "bus_datatype": "int16", "datatype": "uint16", "type": "register", "address": 6, "writable": true} ] }

and the script in LM1 is:

Code:

if not mb then   require('genohm-scada.eibdgm')   require('luamodbus')   -- Elenco mappature bobine, a partire da 0   coils = { '1/1/1' }   -- Elenco mappature dei registri, a partire da 0   registers = { "1/2/0", "1/2/3", "1/2/4", "1/2/9", "1/2/14", "1/2/16", "33/0/1" }   -- Elenco tipo di dati del registro, il conteggio degli elementi deve corrispondere alla tabela dei registri   regdt = { dt.uint16, dt.uint16, dt.uint16, dt.uint16, dt.uint16, dt.uint16, dt.uint16 }   -- Richiamo in scrittura del gr.

can someone help me?
