Configuring the Ethernet Channel for Local Communication

Create Program and Configure Comms Drivers

1. You are now ready to create your ladder logic. An example is

shown below. In this example, there are two SLC 5/05
processors. The MSG instruction from the first processor reads
the seconds value of the Real Time Clock (S:42) from the second
processor and constantly places the value in the first processor’s
file at N7:60. Add the MSG rung to the ladder.
Note:

The control block length for Ethernet MSGs is
51 words (when not using Logical ASCII
addressing).

2. In the “Message Setup” window, enter the MSG parameters and

click “OK”. Then click on the “verify file” button at the top of
the screen. Then save your program file.

3. With RSLogix500 still up and running, click on the RSLinx

program previously minimized at the bottom of the screen.

4. When the RSLinx window appears, click on the

“Communications” pull-down menu and select “Configure
Drivers”.

5. In this step, you will configure the Ethernet driver.

Note:

If you have not configured the RS232 DF1
Device, refer to the procedure “Define SLC 5/05
Processor and I/O Modules” on page 3–2
before configuring the Ethernet driver.
