‘Auto set time/date’ sets the time automatically from the computer’s clock. It firstly measures the
delay between sending a new line and receiving a prompt, and then plans a moment to set the time
every ten seconds. On setting the time, the new line is sent at a calculated moment before the second
to attempt the most accurate time synchronization. Serial is the fastest medium with latencies of a few
milliseconds; Ethernet latencies are at least twenty times longer. This still cannot be accurate to the
millisecond, and only IRIG can provide true millisecond timestamping.
‘I/O Module Options’ provides the diagnostic privileged access password and chooses the data to
be collected from I/O modules. The Analysis Tool must have the diagnostic password entered before
collecting data from I/O modules. The options dialog will appear if you try collecting or erasing I/O
modules without having entered the password.
Enter the diagnostic password. The password may be changed using the System.INI configuration file;
if in doubt, contact [email protected].
You can also choose:
Collect logs: whether to get the event logs from the I/O modules plus general data, or just the
general data. This can be used to speed up collection if you aren't interested in the logs; they can take
a long time to collect and can be very large.
Collect from slice: you can speed up diagnostics by just collecting from faulty slices. Choose
the slice you want; the default is all three.
