Hi
If you use profile here is how to check status of modbus device

Code:

function checkrtu(slave)
local res = db:getone('SELECT active FROM modbus_devices WHERE proto="rtu" AND slave=?', slave)
return toboolean(res)
end

function checktcp(ip, port)
local settings, res
settings = tostring(ip) .. ':' .. tostring(port)
res = db:getone('SELECT active FROM modbus_devices WHERE proto="tcp" AND settings=?', settings)
return toboolean(res)
end
