2.1 Location of Configuration Files
All files that are required for the proper operation of RexCore are located in a configuration directory. The configuration directory is /rex/rexcore in the case of GNU/Linux or in the REX Controls directory in the All users profile in the case of Windows, which should be C:\ProgramData\REX Controls\REX<version>\RexCore in most cases.
Following files may be present in the configuration directory:
- license.txt – A file containing licensing keys for the device. It may be placed manually by a user to the device, but using a RexDraw or RexView tools for licensing operations is most common.
- exec.rex – A binary file with the control algorithm configuration. A user should not touch the file unless he or she knows exactly what to do.
- hmi.rex – A binary file with the Human-Machine Interface configuration. A user should not touch the file unless he or she knows exactly what to do.
- auth.rex – A binary file with the configuration of users, groups and permissions. A user should not touch the file unless he or she knows exactly what to do.
- rexcore.cfg – A textual file for RexCore with all configuration options that are available and which may be adjusted by a user. A detailed options description is provided in section 2.2.
