The Ethernet interface is configured in the PNOZmulti Configurator (for description see on­
line help for the PNOZmulti Configurator).
The communication module PNOZ m ES ETH supports Modbus/TCP [ 45] .
The module can manage up to 8 Modbus/TCP connections and up to 4 PG port (Port 9000)
connections.
5.3.3 Module features
} Can be configured in the PNOZmulti Configurator
} Network protocols: TCP/IP, Modbus/TCP
} Status indicators for communication and for errors
} Transmission rate 10 MBit/s (10BaseT) and 100 MBit/s (100BaseTX), full and half du­
plex
5.3.4 Modbus/TCP
There is no need to configure a connection on the PNOZ m ES ETH. Port 502 is used in
accordance with the Modbus/TCP specification.

5.3.5 RJ45 interfaces ("Ethernet")
Two free switch ports are provided as Ethernet interfaces via an internal autosensing
switch. The autosensing switch automatically detects whether data transfer is occurring at
10 Mbit/s or 100 Mbit/s.
INFORMATION
The connected subscribers must support the autosensing/autonegotiation
function. If not, the communication partner must be set permanently to "10
Mbit/s, half duplex".
The switch's automatic crossover function means there is no need to distinguish on the
connection cable between patch cable (uncrossed data line connection) and crossover
cable (crossover data line connection). The switch automatically creates the correct data
line connection internally. Patch cable can therefore be used as the connection cable for
end devices as well as cascading.
Both Ethernet interfaces use RJ45 technology.
5.3.6 Requirements of the connection cable and connector
The following minimum requirements must be met:
} Ethernet standards (min. Category 5) 10BaseT or 100BaseTX
} Double­shielded twisted pair cable for industrial Ethernet use
} Shielded RJ45 connectors (industrial connectors)
