9.1.3
Use of Hubs and Switches
The specifications on the
Use of Hubs and Switches
are only valid for the
PC cards cifX as follows:
PC Cars cifX
Part No
up to Serial Number
CIFX 50-RE
1250.100 22414
CIFX 50E-RE
1251.100 20167
For the corresponding communication systems, the use of hubs and/or
switches is either forbidden or allowed. The following table shows the
acceptable use of hubs and switches by each communication system:
Communication System
Hub
Switch
EtherCAT
forbidden
only allowed between EtherCAT Master and first EtherCAT Slave
(100 MBit/s, Full Duplex)
EtherNet/IP
allowed
allowed
(10 MBit/s/100 MBit/s, Full or Half Duplex, Auto-Negotiation)
Open Modbus/TCP
allowed
allowed
(10 MBit/s/100 MBit/s, Full or Half Duplex, Auto-Negotiation)
POWELINK
allowed forbidden
PROFINET IO RT
forbidden
Only allowed if the switch supports ‚Priority Tagging’ and LLDP
(100 MBit/s, Full Duplex)
sercos
forbidden forbidden
VARAN*
forbidden forbidden
Table 71: Use of Hubs and Switches
*Instead of hubs and switches VARAN uses splitter. [3]
Failure of the Network Communication
Do not operate hardware with the communication controllers netX 50,
netX100 or netX 500 with the protocols Ethernet TCP/UDP/IP,
EtherNet/IP or Modbus TCP at 10 MBit/s in half-duplex mode, otherwise
failure of the network communication can occur.
Use only switches or 10/100 MBit/s dual-speed hubs and ensure that
the network operates at 100 MBit/s and in full-duplex mode.
For further information refer to section Failure in 10 MBit/s Half Duplex
Mode and Workaround on page 65.
