Configuation data for motoplus app

Hello.

Is there any recommended place to store some configuration data for motoplus application? I need store some flags, integer values and maybe strings

I made some requirements for motoplus application configuration file:

1. Remote editing (FTP for example)

2. Prohibit or complicate the accidental deletion of this configuration file

3. Useful file format with comments/understandable variable names. I think json is ideal

I found one solution: create a JOB that will write variables, like this:

'Tool mass
SET R001 5.0

and then from motoplus app read this variables
