Ethernet Port Status Indicators
Each external switched port has an associated link-up/link-down status bit that can be monitored by the RX3i
CPU to check the operating status of the port (see
Diagnostics, for information
about the PROFINET Controller status bits). In addition, the
Port Number
LEDs on the front of the module
provide a visual indication of the port status.
1.5.3
USB Port(s)
The USB ports on the CPUs that support embedded PROFINET operate independently of the PROFINET
function. Refer to the corresponding product documentation for further details.
The PNC001-Bxxx module has no micro USB port, and therefore does not support the Command Line Interface.
The PNC001-Ax module has a micro USB port for connection to a computer running Windows® 2000, Windows
XP, Windows Vista®, Windows 7 or Windows 10. On the PNC001 module (-Ax version) only, the USB port can
be used to access the Command Line Interface (CLI) function using a terminal emulation application such as
HyperTerminal.
The Command Line Interface function can be used to monitor a PROFINET Controller module and check its
operation. If a problem occurs, the Command Line Interface can be used help determine the cause.
A driver-install application is provided to set up a computer to communicate with the USB port (see Chapter 2,
for instructions).
1.5.4
Reset Pushbutton
The Reset pushbutton on a PNC001 module can be used to manually reset the module without cycling power.
The restart operation commences when the pushbutton is released.
1.5.5
LEDs on the CPUs with Embedded PROFINET
Refer to the corresponding product documentation for further details.
1.5.6
LEDs on the PNC001 Module
The table below summarizes LED functions on the PNC001 module. More detailed information about error
indications and special blink patterns is given in Chapter 2,
and Chapter 5
OK
Green ON indicates that the module is able to perform normal operation.
LAN
Indicates network packets are being processed by the network interface (not just passing through the
embedded switch).
STATUS
Indicates the condition of the PROFINET Controller during normal operation. It indicates whether an entry
other than the start-
up event is present in the module’s
Local Log.
STATUS
can also indicate whether any of
the MAC addresses are invalid.
CONFIG
Indicates whether the module has received its configuration from the RX3i CPU.
ACTIVE
Indicates the status of PROFINET connections.
USB
Indicates activity on the USB port. (PNC001-Ax only)
Port
LEDs
Indicate link speed, link connection and link activity corresponding to the four possible external Ethernet
ports.
