4.3 Operating principle
The CODESYS-3 controller TBEN- L PLC-... can be used to control smaller or modular machines
or for signal preprocessing. The device can be used in various Ethernet networks or fieldbus
systems as master/controller (Modbus TCP, Modbus RTU, PROFINET, EtherNet/IP™, CANopen,
SAE J1939) or slave/device (Modbus TCP, Modbus RTU, PROFINET, EtherNet/IP™, CANopen) and
communicates with bus nodes or higher-level controllers. As a protocol converter between two
networks, the TBEN-L...-PLC-... can for example act as a CANopen manager of a machine module
networked with CANopen and connect it to a system that is networked with PROFINET. In DUAL
MAC mode, the controller transmits data from an internal machine network to the external
Turck Cloud Portal as a participant in two separate Ethernet networks, for example.
4.4 Functions and operating modes
4.4.1 Switch Mode
In switch mode, the two Ethernet ports of the TBEN-L...-PLC-... are treated as one autocrossing
switch with one IP address [
} 25].
NOTE
Devices with a firmware version lower than V1.4.6.0 can only be operated in switch
mode.
4.4.2 Dual MAC Mode (firmware version higher than V1.4.6.0)
In Dual MAC mode, the two Ethernet ports of the TBEN-L...-PLC-... are treated as separate Ether-
net ports with own MAC and IP addresses. The TBEN-L…-PLC-… can therefore be a participant
in two different Ethernet networks in dual MAC mode. The two IP addresses of the separate
Ethernet ports must be located in different subnets [
}
25]
Example:
Port P1 (ETH1):
n
IP address: 192.168. 1 .xxx
n
Subnet mask: 255.255.255.0
Port P2 (ETH2):
n
IP address: 192.168. 2 .xxx
n Subnet mask: 255.255.255.0
NOTE
To use the TBEN-L...-PLC-... in separate networks with combined master/slave func-
tions (see Master/Slave [
} 13]), the device must be operated in dual MAC mode.
