Turck modbus communication

As suggested earlier you should use a profile instead of a script.
Here's a script that handles disconnect correctly. Make sure that script sleep time is larger than 0.

Code:

if not mb then   require('luamodbus')   mb = luamodbus.tcp()   mb:open('192.168.0.162', 502)   res = mb:connect()   log('stato modebus', res) end if mb then   value = mb:readinputregisters(9216)   log('valore di value', value)      if not value then     mb:close()     mb = nil   end end
