Appendix B – Configuring the PC for Ethernet subnetworks
Manual – ECC-DFC field bus controller
Figure 41 Available subnetworks for each typical subnet mask value
As you can see, it is possible to configure the PC using simple subnet mask val-
ue manipulation so that it recognizes several networks.
10.2. Configuration example
The IP address of the PC is used by the Ethernet network to identify the PC in a
network. In the majority of office networks, the IP address is automatically as-
signed by the office network; in smaller networks (such as home networks), the
IP address is issued by a router. In some cases, your IT department assigns a
fixed IP address to your PC or laptop.
In this example, communication is to take place with up to 4 separate subnet-
works. With a correctly configured PC, you can use the ECShell engineering
software to examine and modify the parameters for all modules in all 4 networks.
The following figure shows how the IP address settings of the PC should be con-
figured:
