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 tim
e 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.
