4.3.5.1 Bit7: Simulation of the Synchronisation Status "Radio"
B7
Simulation of the synchronisation status "Radio"
0
Status of synchronisation is only set by the synchronisation source
Activating the operation mode R_SIM with simulation of the synchronisation
1
status "Radio"
Valid for all synchronisation modes
When the Control Byte Bit 7 is set to 1 the control board 7020 simulates the synchronisa-
tion status 'R'. This function is helpful in particular in testing configurations with no antenna
or synchronisation source available when connected systems require a synchronisation
status "Radio" for correct function.
The setting influences the following functions and components of the System 7001:
•
Indication of the operation mode R_SIM
•
Indication of the synchronisation status "Radio"
•
Data output which depends on or contains the synchronisation status
•
ERROR – message concerning the synchronisation status

Time Status
• Operation mode R_SIM will not be activated.
• The setting Control Byte Bit 7 remains stored fail-
safe. That means after a system reset or similar the
Invalid
activation persists.
• Operation mode R_SIM is activated only after setting
a valid system time.
• Operation mode R_SIM will be activated immediately
and stored failsafe.
Valid
• Operation mode R_SIM can only be deactivated with
the setting Control Byte Bit 7 = 0.
• Operation mode R_SIM will not be activated..
• The setting Control Byte Bit 7 remains stored fail-
safe. That means after a system reset or similar the
Invalid
activation persists.
• Operation mode R_SIM is activated only after setting
a valid system time.
• Operation mode R_SIM will be activated immediately.
Valid
• Operation mode R_SIM will be automatically deacti-
vated after 4 hours or after a system reset or similar.
While the synchronisation status is "R" time leaps may occur when the op-
eration mode R_SIM is active:
•
When the system time is set manually. The synchronisation status
will not be reset in this case.
•
At synchronisation via the connected synchronisation source
(GPS_M, DCF_T, MA_SL etc.), when the system time deviates
from the time of the synchronisation source.
