5.1.4 Functional Specifications
 PLC processor in-chassis EtherNet/IP bridge to optimize data throughput
while communicating with HMI or SCADA and other control platforms without
losing valuable process control bandwidth
 Support of up to 4000 PLC registers user data files
 User-definable module memory usage
 10/100 Base-T Ethernet compatible interface
 Functions as a server or a client
 Configurable parameters for the client include:
o A minimum response delay of 0 to 65535 milliseconds
o A response timeout of 1 to 65535 milliseconds
o A retry count of 0 to 20
 Status data available in ladder logic
Support for PLC processor programming over Ethernet using a TCP/IP service
and a serial port on the module connected to channel 0 of the processor. The
module’s third port emulates Channel 0 of the processor to pass through
messages from the port to the processor
Server Specifications

Supports EtherNet/IP explicit, connected, and unconnected class messaging
 Twenty independent server connections permit remote clients to interact with
all data contained in the module
 Data can be derived from other clients on the network, through the client on
the module, or from the PLC processor
Client Specifications

Actively issues connected, explicit messages to other nodes on the network
 Supports 100 user-defined commands from a single client
 Allows command control from ladder logic
 Pass-through services
 Permits remote programming of the PLC processor on the Ethernet network
via a pass-through
 TCP/IP service and a serial communication port (pass-through port) on the
module
 The third port on the module can emulate the Channel 0 port on the PLC,
This allows a DF1 master device attached to the emulated (Channel 0) port to
monitor and control data in the PLC
