FAULT LED
The FAULT LED indicates the condition of the VersaMax node. On a successful power-up, the
LED is initialized to OFF. The FAULT LED remains OFF during normal operation when no
PROFINET diagnosis conditions are present on the PROFINET Scanner itself, or any module in
the node. When a PROFINET diagnosis condition exists, the FAULT LED turns solid amber.
When all diagnosis conditions have disappeared, the FAULT LED is OFF.
The FAULT LED blinks red (0.5 seconds ON/0.5 seconds OFF) if any of the MAC addresses
read from non-volatile memory on power-up are invalid. The PROFINET Scanner remains
disconnected from the Ethernet network if any of its MAC addresses are invalid.
Missing, failed, or mismatched modules in the remote node do not affect the PROFINET
Scanner FAULT LED.
CONNECT LED
When a new PROFINET Scanner module powers up for the first time, it has no network name.
The CONNECT LED slowly blinks amber to indicate that the module is not ready to use. After a
name is assigned, the CONNECT LED goes OFF.
If the PROFINET Scanner has an assigned network name, the CONNECT LED is OFF after a
successful power up. It turns ON solid Green when the primary IO-Controller has established
communications with the module. It turns ON solid Amber when the Backup IO-Controller has
established communications with the module. It turns OFF when communications are
terminated.
The CONNECT LED blinks amber rapidly when the PROFINET Scanner is updating the
firmware of a module in the remote node, or the PROFINET Scanner is in Maintenance Mode,
indicating that all PROFINET connections are blocked.
LAN LED
The LAN LED blinks ON when the module is actively processing Ethernet packets (Tx/Rx). The
LAN LED is OFF if there is no activity.
Port LEDs (10/100 Mbps and Link/Activity)
The two Port LEDs indicate link speed, link connection and link activity on the Ethernet ports.
Green indicates the associated port is connected at 100Mbps. Amber indicates the associated
port is connected at 10Mbps. If a PORT LED is solid ON, the port is connected but is not
currently receiving or transmitting Ethernet frames. A Port LED blinks when Ethernet frames
are actively being transmitted or received. A Port LED is OFF if its associated Ethernet port is
not connected to an Ethernet switch.
