Tcp script event loop
#3
(21.09.2020, 07:24)admin Wrote: Do you have some extra communication in the script? You won't get any improvements on CPU usage if you're only reading from TCP and updating object values.

What is the best way to achieve what i need?

Below is what i currently have in resident script, i need to log out and log in every 15 min to maintain connectivity, and also have object event script sending to udp server in this script to send the client:write() to alarm to activate outputs, i was thinking as i currently use mqtt with https://forum.logicmachine.net/showthread.php?tid=2670
i can utilize the local bus in the event loop without the need to have an additional event script as well as having the on_timer function in the above link running the login/out function every 900 sec.

is it advisable to use the event loop?

Code:
--log in-- function log_in()   ip, port = "192.168.1.61", 1918     client = assert(require('socket').tcp())   client:connect(ip, port);   client:settimeout(0.5);   log("Connecting to Alarm at ip:" .. ip .. ' port: '.. tostring(port)..' at '.. os.date("%H:%M:%S"));     -- log("logging Out of alarm")   client:send(string.char(0x49,0x43,0x08,0x00,0x00,0x00,0x00,0x03))   -- log("logging In")   client:send(string.char(0x49,0x43,0x0D,0x00,0x00,0x00,0x00,0x02,0x01,0x02,0x03,0x04,0xFF))   -- log("Setting alarm timeout")   client:send(string.char(0x49,0x43,0x0A,0x00,0x00,0x00,0x00,0x04,0x70,0x17))   --  log("Turning alarm events on")   client:send(string.char(0x49,0x43,0x0A,0x00,0x00,0x00,0x00,0x06,0x01,0x01)) end log_in_time = os.time() + 900 log_in() while true do   --re log out/in after 15min --   if os.time() > log_in_time then     client:close()     log_in()     log_in_time = os.time() + 900   end     --udp server for recieving commands from event script if not server then   server = require('socket').udp()   server:settimeout(1)   server:setsockname('127.0.0.1', 5432)   log("Udp Server:5432 Recived message") end     cmd = server:receive() if cmd then     if cmd == "Gate_Lock" then       client:send(string.char(0x49,0x43,0x0C,0x00,0x00,0x00,0x01,0x00,0x01,0x00,0x00,0x00,0x0A))     end     if cmd == "Gate_UnLock" then       client:send(string.char(0x49,0x43,0x0C,0x00,0x00,0x00,0x01,0x02,0x01,0x00,0x00,0x00,0x0A))     end       end     --recieving data--   rx = client:receive()   function to_bool(state)   if state == 'Opened' then       return true, state     end     if state == 'Closed' then       return false, state   end end   if rx then     rx = string.gsub(rx, ".", function(value) return  string.format('%02X', string.byte(value))end)     msg = string.sub(rx, 19)     data_type = string.sub(rx, 13,16)    -- loghex(msg)     msg = string.gsub(msg, '%x%x', function(value) return string.char(tonumber(value, 16)) end)     log(msg)     t =  string.split(msg, ' ')        -- Zone name is always in t[2]     if t[2] == 'Zone_1' then       -- Zone state is always in t[4]       state = to_bool(t[4])       grp.write('1/1/1', state)     end       end end
