5.1 Power-up and Reset (PNC001 Module)
During power-up and reset, the PNC001 module runs diagnostics and initializes its hardware
components. When the necessary hardware components have been initialized and tested,
the PNC001 transitions to either normal operation or firmware update mode.
As the PNC001 module transitions to normal operation, it adds a startup entry that provides
a reason for the restart in its Local Log table. This entry is normal.
5.1.1 Module Restart
The PNC001 restarts if it receives a Reset signal from the PACSystems RX3i CPU, if the
Restart Pushbutton is pressed, if the restart or default command is issued from the
Command Line Interface (refer to the PROFINET Controller Command Line Interface
Manual, GFK-2572), or if the hardware watchdog timer expires. More details on each type
of restart are given below.
