Cause : Terminal initialization has failed. An internal software error occurred while the terminal functions were being initialized.
Fault value (r0949, interpret hexadecimal): Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (power off/on) for all components.
- upgrade firmware to later version.
- replace the Control Unit.
