Backup include modbus settings - MantasJ - 14.08.2019

Hello,

We're using this example: https://openrb.com/e-mail-backup-file-once-a-month-from-lm/ to make our LM backups, but they don't contain modbus settings. Is it possible to integrate these settings in a backup file, or I have to think of a separate way to do this?

Thank You.

Heres a function to enable RTU. Change RTU settings as you please.

Call this function in init. You should also set a storage so you know it has been done, so you don't enable RTU each time the device reboots.

Code:
function enableRTU()

-- Function to send request (in this case to enable modbus RTU with settings)
function webrequest(mod, act, vars, data)
require('json')
require('dbenv')
require('uci')
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


-- RTU settings (Change these to your liking)
Set_enabled = 1
Set_port = "/dev/RS485"
Set_baudrate  = 19200
Set_parity = 2
Set_duplex = "H"
Set_port1 = ""
Set_baudrate1  = 115200
Set_parity1 = 2
Set_duplex1 = "H"
Set_port2 = ""
Set_baudrate2  = 115200
Set_parity2 = 2
Set_duplex2 = "H"


-- Input settings
requestdata = {
    enabled = "" .. Set_enabled,
    port = "" .. Set_port,
    baudrate = "" .. Set_baudrate,
    parity = "" .. Set_parity,
    duplex = "" .. Set_duplex,
    port_1 = "" .. Set_port1,
    baudrate_1 = "" .. Set_baudrate1,
    parity_1 = "" .. Set_parity1,
    duplex_1 = "" .. Set_duplex1,
    port_2 = "" .. Set_port2,
    baudrate_2 = "" .. Set_baudrate2,
    parity_2 = "" .. Set_parity2,
    duplex_2 = "" .. Set_duplex2,
  }
result = webrequest('plugin', 'modbus', {request = 'config-save'}, requestdata)

  -- Results for log
if result == '{"success":true}' then
    alert('Modbus RTU enabled')
else
    alert('Enable Modbus RTU FAILED!')
end
 
end
