| **Validated devices/series**   | Mitsubishi QJ71E71                                 |
| **Replaced with Gen 2 driver** | [Mitsubishi QJ71E71](docId\:fMNTPyWvoIqVeQOidccC2) |

To set up and configure this device in Litmus Edge, you will need to do the following:

- Step 1: Set up and Configure the PLC Device
- Step 2: Set up the PLC Device in Litmus Edge DeviceHub
- Step 3: Configure the List of Registers

# Step 1: Set up and Configure the PLC Device

:::hint{type="info"}
**Note**: Only one connection is allowed per port defined in the PLC. See the steps below to view and edit the open ports on the PLC.
:::

If the device is configured for Ethernet access, find its network parameters. Otherwise, follow the steps below. 

**To configure your device:**

1. Note down the following information and refer to it as needed. ****
