NETWORK INSTALLATION
This chapter presents recommendations related to equipment installation in an Ethernet network.
4.1
IP ADDRESS
Every equipment in an Ethernet network needs an IP address and subnet mask.
The IP addressing is unique in the network, and each equipment must have a different IP. The subnet mask is used
to define which IP address range is valid in the network.
For the smart relay SRW01-ETH, the programming of the IP address is made using parameters and the addressing
switches present in the product. The address configuration options depend on the protocol according to the product
model - Modbus TCP, EtherNet/IP or PROFINET IO. See the chapter about the desired protocol for the description
of these options.
4.2
COMMUNICATION RATE
The Ethernet interfaces of the SRW01-ETH smart relay can communicate using the 10 or 100 Mbps rates in half or
full duplex mode.
The baud rate is programmed at P0753.

NOTE!
It is important that, for each Ethernet connection made between two points, the baud rate and the
duplex mode are set to the same option. If the option AUTO is used in one of the points, you must
set the other point also to AUTO, or to half duplex mode.
For PROFINET IO interface, the baud rate is locked to 100 Mbps as required by the protocol.
4.3
CABLE
Recommended characteristics for the cable:
Standard Ethernet cable, 100Base-TX (FastEthernet), CAT 5e or higher.
Shielded cable.
Maximum length between devices: 100 m.
For installation, it is recommended the use of shielded Ethernet cables specific for use in industrial environment.

NETWORK TOPOLOGY
To connect SRW01-ETH smart relay in an Ethernet network, usually the star connection is made using an industrial
switch.
