Configuration
BC9000 and BC9100 31Version: 4.0.0
5 Configuration
5.1 Configuration using the System Manager
Enter a general Ethernet card in the TwinCAT System Manager under devices. If the Bus Couplers are
already connected to the network and have IP addresses, you can also read these. This will cause all the
Bus Couplers with Bus Terminals and their configurations to be loaded. You can then adapt these to meet
your requirements.

Commissioning with 6 or more Ethernet nodes
If you enter more than five nodes in the System Manager, you will have to increase the router memory. You
will find this setting in the System Manager under Real Time Settings. Enter 350 kB there for each Bus
Coupler. This will give, for instance, 3.5 MB (10 x 350 kB) for 10 Bus Couplers.
Fig.19: Setting the router memory
Note: The router memory depends on your PC's main memory, and there is a limit to how high it can be set.
Calculation of the maximum possible router memory:
max. router memory [MB] = (1 MB +((RAM [MB] - 4 MB ) x 0.4)
Sample
Suppose your PC has 128 MB of RAM:
1 MB +(128 MB - 4 MB) x 0.4 = 50.6 MB
So the maximum size of the router memory must not exceed 50.6 MB if there is 128 MB of RAM.
