Connect Node 1 and 2 on the G3-PLC GUI

The first action to perform with the G3-PLC GUI is to add two nodes. Click on the small

cross on the top of the empty panel twice to open two tabs, as described in Section 3.1 on

page 8.

For the following examples, the Node 1 enhanced Com port is mapped on the COM57 of the

personal computer and the Node 2 enhanced Com port is mapped on the COM59.

PHY layer data exchange

To be able to execute a PHY command, the Node 1 and 2 working modes need to be set to

the PHY mode, as explained in Section 5 on page 17.

Now the direction of the data flow needs to be defined. Because it is a point-to-point

communication, there must be one node acting as a sender and one acting as a receiver.

The Node 1 may be configured as the sender, and the Node 2 as the receiver.

For the Node 1, as shown in Figure 31, go into the PHY menu / PLME_Control panel (1) to

configure the state of the node. Check the TXON_RXOFF (2) parameter and click on the

PLME_SET_TRX_STATE.Request button (3).
