PNC001 Time Synchronization with the Host RX3i CPU

The internal clock value of a PNC001 module may be displayed in Command Line Interface (CLI) commands,
and it is used to timestamp entries in the PROFINET Controller Local Fault Log as they occur.
The internal clock of the PNC001 module is synchronized with the RX3i CPU clock whenever the PNC001
module is:
•
powered up, or
•
hot-inserted, or
•
reset via the Reset pushbutton, or on command from the Command Line Interface.
Storing hardware configuration to the PNC001 module does not cause clock synchronization.
If the host CPU's time is changed after the PNC001 module synchronizes its own internal clock, the PROFINET
Controller's internal clock is not automatically synchronized until the PNC001 module is again powered up,
hot-inserted, or reset.
The internal clock of the PNC001 module may be set from the Command Line Interface at any time, using the
time command.
