Integrating the Rockwell Automation 2711R PanelView 800 HMI with PLCs requires establishing connectivity between the two devices in order to exchange data and control signals. The following are the general steps for integrating the HMI with PLCs:
1. Establish a physical connection:
Make that the PanelView 800 HMI and PLC are connected with the appropriate hardware. The HMI and the PLC’s communication port are normally connected through an Ethernet or serial cable in this situation.
- Identify the communication ports: Discover the HMI’s and the PLC’s available communication ports. Ethernet, serial (RS-232 or RS-485), and USB are popular choices.
- Choose the appropriate cable: Depending on the HMI and PLC’s communication ports, choose the right type of cable. An Ethernet cable (such as Cat5e or Cat6) is commonly used for Ethernet transmission. A cable with an RS-232 or RS-485 connector may be needed for serial communication. Use a USB cable if USB communication is supported.
2. Configure communication settings on the HMI:
Through the software interface, you can access the Rockwell Automation 2711R PanelView 800 HMI setup options. To establish contact with the PLC, specify the communication protocol, IP address, and other details. Depending on the software version and PLC model you’re using, the precise steps may change.
- Power on the HMI: Make that the HMI is turned on and plugged into a reliable power supply.
- Launch the Configuration Mode: Tap and hold the upper-left corner of the HMI’s screen for about 10 seconds to bring up the Configuration Mode screen.
3. Configure communication settings on the PLC:
Configure the PLC’s communication parameters to correspond to the HMI’s. To enable communication with the HMI, set the communication protocol, IP address, and other necessary settings.
- Launch the PLC programming software: Open the programming tool offered by the PLC manufacturer, such as Schneider Electric’s Unity Pro for Schneider Electric PLCs, Siemens TIA Portal for Siemens PLCs, or Rockwell Automation’s RSLogix or Studio 5000 for Allen-Bradley PLCs.
- Connect to the PLC: Create a link between the PLC and the programming software. A connection (Ethernet, serial, or USB) is commonly connected between your computer and the PLC’s communication interface to accomplish this.
- Access the communication settings: Navigate to the communication settings section of the programming software after connecting to the PLC. In this section, the PLC’s communication settings can be configured.
4. Define tags on the HMI:
Define tags that reflect the data points you wish to monitor or control on the PLC in the HMI software (such as FactoryTalk View Machine Edition). These tags can contain any information that has to be transmitted between the HMI and the PLC, such as input values, output values, status flags, or other data.
- Launch the HMI configuration software: Launch the Rockwell Automation software application for PanelView 800 HMI configuration. Depending on the setup and version you have, this could be FactoryTalk View Studio or another suitable programme.
- Create a new project or open an existing project: Open an existing project or begin a new one in the HMI configuration software. You will have access to the interface for managing and defining tags using this.
5. Map tags to PLC memory addresses:
Connect the HMI tags to the PLC’s memory addresses or registers that correspond to them. This guarantees that the HMI can access the proper regions in the PLC’s memory to read and write data.
- Assign the PLC memory address: Find a field or property in the Tag Editor that relates to the PLC memory address or PLC tag reference. The memory address in the PLC where the corresponding data for the tag is stored can be specified using this field.
6. Design HMI screens:
Create the graphical user interface and screens for the HMI application using the HMI software. Make screens with buttons, indications, alarms, and other controls so that operators may communicate with the PLC.
- Position and size objects: Layout the objects on the screen in the desired order and position. Adapt the objects’ dimensions, forms, and orientation as necessary.
- Customize object properties: Make each object’s properties unique to specify its appearance, behaviour, and functionality. The text, font, colour, fill, border, animation, visibility, and related actions may all be specified in this way.
7. Bind HMI objects to PLC tags:
Connect the PLC tags that match to the objects on the HMI screens. By creating a link between the HMI objects and the PLC data, real-time data interchange and control are made possible.
- Access the object’s properties: Access the object’s properties in the configuration programme while it is chosen. Look for the data binding or tag association attribute.
- Bind the object to a PLC tag: Enter the PLC tag that you wish to bind the object to in the object’s properties. To do this, put the name or reference of the PLC tag in the relevant area. The software may require you to browse or search for the required PLC tag.
8. Test the HMI-PLC communication:
Run the HMI application to check that the PLC connectivity is working properly. Check that the HMI displays the correct values, keep an eye on the data transfer between the HMI and the PLC, and verify the control actions to make sure the PLC reflects them correctly.
- Ensure proper physical connection: Ensure that the HMI and PLC are powered on and physically connected to one another using the proper communication line.
- Verify communication settings: Make sure the HMI and PLC’s communication settings are configured properly by checking them twice. In addition to the baud rate, parity, and other pertinent data, this also comprises the communication protocol, IP addresses, and port numbers.
Once the HMI-PLC integration is in place, keep an eye on the system’s operation and communication. To maintain the integration’s dependability and performance, perform routine maintenance as needed.
