Is it possible to change different types of parameters with one touch? Imagine - one touch on the HMI visualization panel makes your manufactured product change beyond recognition. For example, from a classic whole wheat sandwich to a gluten-free cupcake with strawberry filling. Two completely different flour products involve not only different ingredients, but also different cooking processes. Changing production data manually is more prone to error. As is known, errors require additional time resources, which are reflected in the company's expenses. To make it easier to manage control panel data, we have created a video material. In this video, we will show you how to send data to a PLC with an HMI recipe
In this article we will look at:
So, in order to send data from HMI (Human Machine Interface) to PLC (Programmable Logic Controller),it is necessary to use appropriate communication protocol and connection between HMI and PLC. The most commonly used protocols for such situations are Modbus TCP, Profibus, Profinet or Ethernet/IP.
An HMI recipe is an EBpro visualization development object that allows you to easily display, edit and send a bunch of pre-defined behaviors in a grouped way to the PLC variables. That is - one touch allows you to define the values of up to 100 variables of yours PLC.
In a manufacturing environment, a recipe (process recipe or batch recipe) sets up machine settings for consistent material handling or production, or batch raw material composition proportions and process flow. In both cases recipe is the basis of the quality of the vital process and the repeatability of the product.
HMI recipes are used when a company produces several products with the same equipment with different production parameters. The HMI recipe is an excellent automation solution to be able to ensure a quick and accurate transfer of production settings from one product to another. If the company produces only one product, then the HMI recipe is not needed, since its production parameters are not changed. The data is simply stored in an automation system that repeats itself regularly.
The two main options for storing an HMI recipe are in the HMI panel or in the PLC controller. It is only practical to store recipes in a controller if there are a few simple steps to be performed and there is only one controller. Using this storage method, creating, viewing, and modifying recipes is difficult because most controllers do not support recipe functionality. Most HMIs support recipe functionality. This makes creating, viewing and editing them much easier.
Primary HMI recipe data is stored in the internal HMI memory so that it can be further transferred to the PLC or simply viewed and corrected on the HMI screen. However, there are several options for adding and changing recipe data.
If you do not manage to create a HMI recipe on your own, then we invite you to watch our prepared video on this topic or contact ZTF Lāsma engineers.
