SYSTEM CONFIGURATION EXAMPLES

System configurration example of Number of inserted HUBs: 2 is shown below.
The number of inserted HUBs is determined by the route, where max. number of HUB is gone through, out of all route.
When HUB module is used, the frame option must be set in any CUnet I/O module connected to the network. Refer to the instruction manual of your CUnet I/O module for the detailed settings.
