Traditionally in an automation project, there were multiple programs needed to program drives, HMI’s, and PLC’s. With Siemens TIA Portal, everything can be done in one platform for the entire project. This means that that an HMI can be inserted right alongside a PLC and Drives in the same project.
So what is an HMI? HMI stands for Human Machine Interface. It is what allows the operator to interact with a PLC, machine, or other types of systems. It is considered an I/O device as you can often give input for things like timers and receive output such as alarms.
When integrating an HMI into TIA Portal, the correct WinCC software must be licensed. These include WinCC Comfort, Advanced, Professional, and Unified. There are separate licenses for Runtime for devices such as thin clients, IPCs, or SCADA. Once the correct version is installed/licensed the HMI can be added to a project.
Once the correct HMI is selected from the drop-down menus it will be added to the project. As long as the Start Device Wizard is checked, a quick and easy wizard will start and help the user commission the newly added HMI.
The wizard will also help to establish a connection between the correct PLC and HMI, as multiple can be seen on the network and connections screen in the TIA Portal software.
Once the HMI is successfully added to the project, screens can be created to provide the information that is needed for the project. There are several graphic options that are included within TIA Portal that can be used to create buttons, I/O Fields, etc. Alarms, recipes, reports, and other useful functions are available at the programmer’s disposal.
Adding a new panel and configuring it for your automation needs has never been easier with Siemens TIA Portal. When you have all the automation devices in one place, there is less time spent programming between automation platforms and less chance for errors when toggling between different programs to get all aspects configured and communicating properly.
