n
Report cause of STOP
–
Activate this parameter, if the CPU should report the cause of STOP to PG
respectively OP on transition to STOP.
n
Number of messages in the diagnostics buffer
–
This parameter is ignored. The CPU always has a diagnostics buffer (circular
buffer) for 100 diagnostics messages.
n
Synchronization type
–
Here you specify whether clock should synchronize other clocks or not.
–
as slave: The clock is synchronized by another clock.
–
as master: The clock synchronizes other clocks as master.
–
none: There is no synchronization
n
Time interval
–
Time intervals within which the synchronization is to be carried out.
n
Correction factor
–
Lose or gain in the clock time may be compensated within a 24 hour period by
means of the correction factor in ms.
–
If the clock is 1s slow after 24 hours, you have to specify a correction factor of
"+1000" ms.
n
Level of protection
–
Here 1 of 3 protection levels may be set to protect the CPU from unauthorized
access.
–
Protection level 1 (default setting):
No password adjustable, no restrictions
–
Protection level 2 with password:
Authorized users: read and write access
Unauthorized user: read access only
–
Protection level 3:
Authorized users: read and write access
Unauthorized user: no read and write access
