APAX-5070 User Manual 18
There is an expansion port on front side of APAX-5002. With this port, users can build
a remote expansion architecture. Standard Ethernet cables can be used to connect
any two APAX-5002. However, shielded industrial Ethernet cable MUST be used
instead of standard Ethernet cable when the system is used in harsh environment,
such as factory automation. Unmanaged industrial Ethernet switches (such as
Advantech EKI-2528) with 100 Mbps transmission speed can also be used between
two APAX-5002. Therefore, you can flexibly build any remote expansion with line,
tree or star topology. All the APAX-5000 I/O modules can benefit from the remote
expansion architecture. Refer to figure below for the expansion topology.
Warning! 1. DO NOT use managed switch, hub or router between backplanes for
expansion.
2. The network for the expansion should be a local network, NOT to con-
nect with other external network (such as public network in enterprise
network, including Internet).
3. Cat 6 Ethernet cable is strongly recommended for better data trans-
mission quality.
4. It is suggested to power on APAX-5070 and all the I/O modules
together to avoid any unpredictable situation.
5. The maximum total amount of APAX-5000 I/O modules used with one
APAX-5070 is 32.
Note! For the line topology, as shown by figure above, the maximum distance
between two backplanes is 100 m.
