At present the following bits are allocated in the Error Byte:
B7
LAN MNG Communication (6844RC only)
0
no error
1
no internal communication with 6844MNG
(can only be transmitted when the LAN MNG Board is enabled)
B6
0
no error
1
currently not implemented
B5
Keypad Input possible
0
no error
1
keypad blocked (at least 4x the wrong keyword entry)
B4
Daylight Saving Time (DST) Changeover
0
no error
1
incomplete data set for daylight saving time (DST) changeover
B3
0
no error
1
currently not implemented
B2
Control of the internal Quartz Basis
0
no error
1
Error in the quartz frequency adjustment
B1
Sync.-Protocol - Data plausible
0
no error
1
time information of sync.-source not plausible
B0
Sync.-Channel - Signal available
0
no error
1
no signal detected on the configured Sync.-Channel (input)
Error Bit 7 = 1
(no communication with LAN MNG)
The Control Board 6844RC is unable to connect to a logged on LAN Management
Board / Module.
Error Bit 5 = 1
(Keypad blocked (at least 4x the wrong keyword entry))
A keyword was set for the keyboard and a wrong entry was made four times in succes-
sion. This error can only be read separately with the
hmc
remote software or a LAN
Management Board/Module.
Error Bit 4 = 1
(incomplete data set for daylight saving time (DST) changeover)
The data for the daylight saving time (DST) changeover were not entered in full. There
is no calculation possible
Error Bit 2 = 1
(Error in the adjustment of the quartz frequency)
There is an error in the internal adjustment of the quartz frequency. The specified sys-
tem accuracy and freewheel stability can't be guaranteed. According to these error the
system stays in Sync.-Status 'C' (crystal).
Error bit 1 = 1
(Protocol / Time information of the Sync.-Source is not plausible)
The protocol being read or rather the time information of the Sync.-Source cannot be
evaluated nor used.
By default the error bit "Sync.-Protocol" is always set after a system reset. After system
start the error bit is set or rather cancelled according to the received Sync.-Protocol.
This error bit is separately operated for each Sync.-Mode. All used Sync.-Protocols of
the respective Sync.-Mode may cause the setting of a failure bit.
