In this article, I am trying to share how to map DF1/DH485 to ControlLogix/CompactLogix PLC.

**Step 1:** Open RSLogix 500.

**Step 2:** Click the Small image of the PLC controller. Can be found under the I/O config on the tree shown folder on the left side of the tab.

**Step 3:** Select **Serial Port** tab from **the controller Properties** window.

**Step 4:** Click on the down arrow from the **Mode** field and choose a system.

**Step 5:** Click the down arrow in the **Data Bits** field and choose **8.**

**Step 6:** For the Baud Rate, Parity and Stop Bits fields, follow the values seen in the Panel Manager configuration in C-more. Leave the Control Line to No Handshake. Leave the RTS delay set to 0.

**Step 7:** Select the **System Protocol Tab** and click the down arrow and from the available choices choose the suitable **Protocol**

**Step 8:** Choose **DF Point to Point,** if you are doing **DF1 Full Duplex.** Then be assure to match the **Error Detection** to the **checksum type** in the panel manager in **C-more.**

**Step 9:** Choose **DF1 Slave,** if you are doing **DF1 Half Duplex** and you should match the Station Address to the PLC Address in the C-more Panel Manager. Also, fit the Error Detection to the Checksum Type in the C-more Panel Manage.

**Step 10:** If you are using **DH485** , compare the **Station Address** to the **Station Number** in the **C-more Panel Manager** configuration. Make sure that the **PLC Station Address** is under the Max Station number configuration in the C-more Panel Manager. Keep all the rest as it is. See the figure below for a guide.

**Step 11:** Once the parameters of the communication link are set, the addresses must also be mapped. In the C-more panel, the DF1 Full, DF1 Half, and DH485 addresses are based on the SLC and the MicroLogix addressing system (N7:xx, etc…). ControlLogix and CompactLogix PLCs are tag-based and do not have these addresses.

To make a connection between the two separate types of addresses, you need to make a mapping table in the RSLogix 5000 program.

**Step 12:** Click the **Logic** and Choose **Map PLC/SLC Messages** from the Main Menu.

**Step 13:** Select the file number that you need and select the desired array to go it.

**Step 14:** Download these changes to the PLC controller once you have done the above steps and you should see your data updating.
