Create Modbus client via script

[Erwin van der Zwart]

Hi,

The new FW requires a extra parameter 'timeout' that old FW didn't use, and also new browsers are blocking credentials in URL so i changed the script in a new methode for web requests.

Thanks to Admin for that (: 

Here is the new script:

Code:

-- Batch adding modbus devices v1.1 - Created by Erwin van der Zwart - Schneider Electric Netherlands -----------
-- For spaceLYnk FW 2.1.1 or higher and Wiser for KNX FW 2.1.1 or higher ----------------------------------------
----------------------------------------------- Start Parameters ------------------------------------------------

Number_of_devices = 10
Device_name_prefix = "Device"
Device_protocol = "tcp"
Device_port = 502
Device_ip_range = "192.168.0"
Device_ip_start = 1
Device_profile = "iEM-iEM3155"
Device_timeout = 3
Device_pollinterval = 5
Device_slave_start = 1

------------------------------------------------ End Parameters -------------------------------------------------
------------------------------------ DON'T CHANGE ANYTHING UNDER THIS LINE --------------------------------------

-- Set counters for creation log
number_of_devices = 0
number_failed = 0

-- Function to send request (in this case to create a modbus device)
function webrequest(mod, act, vars, data)
  require('json')
  require('dbenv')
  local path
  vars = vars or {}
  function getvar(v)
    return vars[ v ]
  end
  json.data = function()
    return data or {}
  end
  if mod == 'plugin' then
    path = 'plugins/' .. act .. '/web.lua'
  else
    path = 'web/' .. mod .. '/' .. act .. '.lua'
  end
  return dofile('/lib/genohm-scada/' .. path)
end

-- Create devices
for i = 0, Number_of_devices - 1, 1 do
 requestdata = {
   id = "",
   timeout = "" .. Device_timeout,
   pollinterval = "" .. Device_pollinterval,
   slave = "" .. Device_slave_start + i,
   port = "" .. Device_port,
   ip = Device_ip_range .. "." .. Device_ip_start + i,
   profile = Device_profile,
   name = Device_name_prefix .. " " .. i + 1,
   proto = Device_protocol,
 }
 result = webrequest('plugin', 'modbus', {request = 'device-save'}, requestdata)
 -- Calculate results for creation devices log
 if result == '{"success":true}' then
   number_of_devices = number_of_devices + 1
 else
   number_failed = number_failed + 1
 end
end

-- Create result log
if number_failed == 0 then
 log ("Created " .. number_of_devices .. " devices succesfully")
else
 log ("Created " .. number_of_devices .. " devices succesfully and creation of " .. number_failed .. " devices failed")
end

-- Disable script when done automaticly
script.disable(_SCRIPTNAME)

BR,

Erwin
