We recommend using the Gen 2 [AB CompactLogix Ethernet FreeTag](docId\:RnJtfL6l5lXb52iFF6QJm). ::: Review the following information for setting up and configuring the AB ControlLogix (Gen1) driver. # Litmus Edge Compatible Series | Compatibility parameter | Compatible items | | ------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Driver type** | Ethernet | | **Validated devices/series** | [Rockwell Automation ](https://www.rockwellautomation.com/en-us/products/hardware/allen-bradley/programmable-controllers/large-controllers/controllogix.html)[Allen-Bradley ControlLogix](http://ab.rockwellautomation.com/)
Certain device drivers do not have a list of register names in the DeviceHub Add Tag form. These are *Free Tag* PLCs. For Free Tag requirements, see [Device Connectivity Status](docId\:okFkYcmKRIrYz8gtRQMh9). | | **Replaced with Gen 2 driver** | [AB CompactLogix Ethernet FreeTag](docId\:RnJtfL6l5lXb52iFF6QJm) | 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 If the device is configured for Ethernet access, find its network parameters. Otherwise, follow the steps below. The instructions listed here provide only the basic configuration steps. Refer to the Rockwell Automation Allen-Bradley PLC documentation for current, complete details. 1. Set the PLC IP address. 2. Create new tags (Controller and Program tags supported). 3. Export tag data to a CSV file: **Tools > Export > Tags and Logic Comments**. The CSV consists of PLC settings along with the Tags which can be read using Litmus Edge. **To configure the PLC:** 1. Note down the following information and refer to it as needed. **Device**: AB ControlLogix 1756-L55 **Communication I/F**: Ethernet. Refer to the following figure. ![](https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/zEQd-2740g_Zsc2OX0rYu_ab-controllogix.png "AB ControlLogix") 2. Launch RSLinx 5000 v16 Software, and then click **Configure Drivers**. 3. Add a new RS-232-DF1 driver. 4. Set up the communication port and parameters, and then click **Auto-Configure**. ![](https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/7QyA_xCTHD9zAx2Q5k1Q5_ab-controllogix-parameters482x338.png "AB ControlLogix parameters") 5. Right-click the **Ethernet communication module > Module Configuration **to set up its network parameters. ![](https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/AxeVXfbt4vsV69LkCoZDY_ab-controllogix-network.png "AB ControlLogix network") 6. Add an Ethernet Device driver. 7. Click **Configure **and select the IP for the device. ![](https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/XLMpMQXePiGDMqEvPduxP_ab-controllogix-configure.png "AB ControlLogix configure") # Step 2: Set up the PLC Device in Litmus Edge DeviceHub Configure the following parameters when you [Connect a Device](docId\:pal6ABPZbrimdU9LvGJ30) with this driver. Update default values to the specific setup of your device. | Parameter | Value | | ------------------- | ---------------------------------------- | | **Type** | Allen-Bradley | | **Driver** | AB ControlLogix (Gen1) | | **Network address** | The device address you defined in Step 1 | | **Port** | 44818 | | **Slot Number** | 0 | # Step 3: Configure the List of Registers :::hint{type="info"} **Note**: The **Browse** icon displayed on the device tile means that this PLC uses Browse Tags. See [Add Tags](docId:8sE7z3PmRfwL1nmzcwaLX) for more information. [Add Tags](docId:8sE7z3PmRfwL1nmzcwaLX) ::: When you [Add Tags](docId:8sE7z3PmRfwL1nmzcwaLX) to the connected device, use the following tag/register mapping table. | **Name** | **Value Type** | | -------- | -------------- | | R | BOOL | | R | SINT | | R | INT | | R | BIT(INT) | | R | DINT | | R | REAL | | R | LINT |
