Ethernet (TCP/IP) Network
The R2P 2.0 Ethernet port is equipped to interface with Modbus TCP/IP also known as Modbus TCP.
This is a variant of the Modbus industrial communication for use over Ethernet local area networks.
Most SCADA systems recognize this communication protocol and there are many drivers available to
operate on OPC enabled architectures.
The Ethernet port should be connected to a network connection via a shielded CAT5 cable. The R2P
2.0 can be connected to a computer with a standard Ethernet cable or a crossover cable. The unit can
be connected to a network with a standard Ethernet cable and a network hub or wall plate
connection. The communication port or protocol used for MODBUS TCP is port 502. This is not a
physical port but a number that is used to route the information to the correct application program.
The unit is recognized over the network by its Internet Protocol Address or IP address. This address
is configurable in the protocol settings in the factory setup screen.

– TCP/IP NETWORK SELECTION
The IP address is in Internet Protocol version 4, 32 Bit format. This is identified by a 4 part number,
with a max of 3 digits per part; each part is no more than 255 and each is separated by a dot. The IP
address consist of two fields; a routing prefix and a host identifier so that communication between
devices can occur. The subnet mask follows the same format and allows for dividing a single network
into two or more networks. The default gateway is on the same subnet as the device and is the
gateway the device relies on when it does not know how to route traffic.
