check slave tcp/IP modbus device status

[domotiqa]

This method won't work with TCP-RTU gateway. One solution is to check updatetime value of a linked object periodically and set status if it was not updated for a certain time.

ok, cool it's a way I could do it !
Maybe, put a tag like 'towatch', and check difference betaween date now and uptime

Something like this:

obj1 = grp.find('x/x/x')
objError= grp.find('x/x/x')

now = os.time() -- current timestamp in seconds
delta1 = now - obj1.updatetime -- last object update relative time

if (delta1 > 240)  then
  objError:write(true)
end


DO you know why it's not implemented ? It works for rtu, and if the gateaway don't respond...


Thank you for helping
