5.1 Ethernet LED Indicators
The Ethernet LEDs indicate the module's Ethernet port status as follows:
LED State Description
Data OFF Ethernet connected at 10Mbps duplex speed
AMBER Solid Ethernet connected at 100Mbps duplex speed
Link OFF No physical network connection is detected. No Ethernet
communication is possible. Check wiring and cables.
GREEN Solid
or Blinking Physical network connection detected. This LED must be ON solid
for Ethernet communication to be possible.
5.1.1 Scrolling LED Status Indicators
The scrolling LED display indicates the module’s operating status as follows:
Initialization Messages
Code Message
Boot / DDOK Module is initializing
Ladd Module is waiting for required module configuration data from
ladder logic to configure the Modbus ports
Waiting for Processor Connection Module did not connect to processor during initialization

Sample ladder logic or AOI is not loaded on processor
 Module is located in a different slot than the one
configured in the ladder logic/AOI
 Processor is not in RUN or REM RUN mode
Last config: <date> Indicates the last date when the module changed its IP
address. You can update the module date and time through
the module’s web page, or with the MVI56E Optional Add-On
Instruction.
Config P1/P2 <Modbus mode>
<Port type> <Baud> <Parity>
<Data bits> <Stop Bits> <RS
Interface> <ID (Slave)> <Cmds:

display the configuration of both ports. The information
consists of:

Modbus mode: RTU/ASCII
 Port type: Master/Slave
 Baud: 115200 / 57600 / 38400 / 19200 / 9600/ 4800 /
2400 / 1200 / 600 / 300
 Parity: None / Even / Odd
 Data bits: 7 / 8
 Stop bits: 1 / 2
 RS Interface: RS-232 / RS-422 / RS-485
 ID: Slave Modbus Address
 Cmds: Configured Modbus Master Commands
