Figure 6.20 – Configured Consumed Exchange 1 - Node 2
6. Node 2 configuration is now complete. Click OK, save the user program using an
appropriate filename, such as EGD Node 2.csp, and then continue with Section 6.8.3, to
start EGD communication between Node 1 and Node 2.
6.8.3 EGD Example 1 – Starting EGD Communication between Node 1 and Node 2
Now that both Node 1 and Node 2 have been configured for EGD Example 1 (Figure 6.6), start
them communicating as follows:
1. Open the saved Node 1 user program (EGD Node 1.csp), and download it to Node 1.
2. Open the saved Node 2 user program (EGD Node 2.csp), and download it to Node 2.
3. Connect both Node 1 and Node 2 to an Ethernet network and put them both in RUN mode.
At this point, Node 1 and Node 2 should be exchanging EGD data as follows:
1. Every 100 mS, Node 1 will read its %R100 through %R109 registers and send them via
Exchange 1 to be received by Node 2 into Node 2’s %R200 through %R209 registers.
2. Every 200 mS, Node 2 will read its %R100 through %R104 registers and send them via
Exchange 2 to be received by Node 1 into Node 1’s %R200 through %R204 registers.
