Modbus Server logging writing IPs

[admin]

You should use this script: https://forum.logicmachine.net/showthread.php?tid=4288

Modify the handler function in the resident script to alert IP/port for each connection:

Code:

local function handler(sock)
  local ip, port = sock:getpeername()
  alert('modbus connection from: %s:%d', ip, port)

  copas.setErrorHandler(log)

  sock = copas.wrap(sock)
  sock:settimeout(60)

  while true do
    local res, err = mb.tcphandler(sock)
    if not res then
      break
    end
  end

  sock:close()
end
