EQUIPMENT CHARACTERISTICS IN ETHERNET NETWORK
Below are listed the main features for Ethernet communication for SRW01-ETH smart relay.
There are 3 different products, according to the specified communication protocol:
–
SRW01-ETH-EIP: EtherNet/IP protocol.
–
SRW01-ETH-MBTCP: Modbus TCP protocol.
–
SRW01-ETH-PNIO: PROFINET IO protocol.
The interface follows the Fast Ethernet 100BASE-TX standard.
It allows communication using the 10 or 100 Mbps rates in half or full duplex mode.
It has a built-in, two-port Ethernet switch.
The Ethernet ports work with Auto-MDIX (automatic medium-dependent interface crossover), a technology which
automatically detects the type of cable used and configures the connection accordingly, eliminating the need of
cross-over cables.
The interface also makes available a Web server (HTTP).
1.1
MODBUS TCP SPECIFIC CHARACTERISTICS
Operates as Modbus TCP server.
The server provides up to 4 simultaneous Modbus TCP connections.
Allows data communication for equipment operation and parameterization, as well as markers and data used for
SRW01-ETH ladder programming.
1.2
ETHERNET/IP SPECIFIC CHARACTERISTICS
It is supplied with an EDS file for the network master configuration.
Allows up to 20 input words and 20 output words for cyclic data communication.
Acyclic data available for parameterization.
Device Level Ring (DLR) and linear network topology supported.
It features up to 2 Modbus TCP connections.
1.3
PROFINET IO SPECIFIC CHARACTERISTICS
It is supplied with a XML file for the network master configuration.
Allows up to 20 input words and 20 output words for cyclic data communication.
Acyclic data available for parameterization.
It features up to 2 Modbus TCP connections.
