setup modbus tcp slave

[buuuudzik]

I've tried to use this modbus TCP slave script and it works perfectly but only when other LM which is master reads by a script it doesn't work via mapper.
The minimum version of profile which I've tested:

Code:

{
  "manufacturer": "PEGO",
"description": "LM4",
  "mapping": [
    { "bus_address": "32/2/0", "name": "Room humidity", "bus_datatype": "uint16", "type": "register", "datatype": "uint16", "address": 0, "units": "%" }
  ]
}

This is the first part of slave script from LM4:

Code:

if not mb then
 require('genohm-scada.eibdgm')
 require('luamodbus')

 -- list of coil mapping, starting from 0
 coils = {  }

 -- list of register mapping, starting from 0
 registers = { '32/2/0' }
    
 -- list of register data types, element count must match registers table
 regdt = { dt.uint16 }

This is currently used master script (it is working very nice, i let only 1 address):

Code:

require('json')
require('luamodbus')

mb = luamodbus.tcp()
mb:open('192.168.2.17')
mb:connect()

-- verbose output and select slave number 1
mb:setdebug(true)
mb:setslave(1)

pego_1_profile_json = [[{
 "manufacturer": "PEGO",
"description": "PEGO_Goscinna",
 "mapping": [
    { "bus_address": "32/2/0", "name": "Room humidity", "bus_datatype": "uint16", "type": "register", "datatype": "uint16", "address": 0, "units": "%" }
]}]]


function readAndUpdatePEGOGAs(pego_profiles)
  for i, profile in ipairs(pego_profiles) do
    pego_profile = json.decode(profile)

    for k,v in ipairs(pego_profile.mapping) do
      
      value, err = mb:readregistervalue(v.address, v.datatype, 'n')
      
      if v.value_multiplier == 0.1 then delta = 0.1 else delta = 1 end
      grp.checkwrite(v.bus_address, value, delta)
      
    end
  end
end


pego_profiles = {pego_1_profile_json}

readAndUpdatePEGOGAs(pego_profiles)


-- close serial connection
mb:close()

-- wait 5 seconds before next read
os.sleep(5)

So currently I am working with above script but I want switch it to the mapper. But in above mapper settings it's not working e.g. when I change value on slave it isn't changed by new read on master. Maybe some advice from some experienced Modbus TCP user?

P.S. No, two scripts don't working in same time
