NOTE:
If you have selected Diagnostic Start mode, the module will perform a series of extensive diagnostic
tests during startup. See section 2.4 on page 13.
3.3. Normal Operation
Status LEDs
Indicator Normal State
Module Status (MS) Steady Green - Operational
Network Status (NS) Steady Green – Operational
Link Status (LS) Steady Green – Physical Link Established
Other LEDs
The state of the other LEDs may vary depending on the method of operation.
Indicator Normal State
Collision (COL) May flash occasionally in normal operation. Heavy activity indicates a
network problem (excessive traffic or faulty cabling).
Full Duplex (FDX) Steady Green – Full duplex, Off – Half Duplex
100 Mb (100 Mb) Steady Green – 100Mb, Off – 10Mb
Serial XMT Will illuminate/flash if the serial port is transmitting data
Serial RCV Will illuminate/flash if the serial port is receiving data
Ethernet XMT Will illuminate/flash if the Ethernet port is transmitting data (see note
Ethernet RCV Will illuminate/flash if the Ethernet port detects a packet being received.
(see note below)
NOTE:
The Ethernet XMT LED may blink periodically, even though no command requiring a response has
been sent to the module because the module is transmitting IP control messages.
The RCV LED does not indicate that Ethernet packets destined for the module are being received; it
merely indicates that there is activity on the Ethernet segment. When a single short frame is received,
the LED blink may not be noticeable. The LED blinks relate to general activity; they cannot be used to
count individual frames.
Server Operation
To use the module as a server, no special PLC logic or configuration is required. You simply provide
a client application that communicates with the module. For example, your HMI application, using a
2572 driver or OPC server, can be used to read and write PLC data. Also, programming software,
such as FasTrack Workshop can be used to program the module via the network.
Client Operation
To use the module to perform client operations, you must include PLC logic that triggers the module
operation. See CHAPTER 5. CAMP CLIENT COMMANDS.
