A PNOZmulti base unit can manage up to 8 Modbus/TCP connections and up to 4 PG port
(Port 9000) connections.
Transmission rate:

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 ca-
ble (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.
Requirements of the connection cable and connector
The following minimum requirements must be met:
} Ethernet standards (min. Category 5) 10BaseT or 100BaseTX
} Double-shielded twisted pair cable for industrial Ethernet use
} Shielded RJ45 connectors (industrial connectors)
