In this blog, we’ve discussed a few different ways to integrate sensors into a Peakboard application. You can see an overview of these articles in The hitchhiker’s guide to I/O devices. In today’s article, we’ll take a look at a sophisticated and slightly more expensive type of I/O module—an IO-Link...
In this blog, we’ve explained how to connect various devices to Peakboard, and build beautiful applications. One family of devices is I/O devices. These are used to connect any kind of sensor, like light barriers, buttons, and temperature sensors. On the output side, we often see actors like traffic lights...
In a previous article, we discussed an I/O module made by the Taiwan-based company ICP DAS. In today’s article, we will discuss another I/O module from the U-7500 series: the U-7560. It has 6 digital inputs and 6 relay outputs. The main difference is that it supports OPC UA as...
In this article, we learned how to subscribe to OPC UA nodes and process the incoming values. The example was based on an A/C that provided several values, like the temperature and power consumption. Make sure to read that article first, because today we will learn how to switch the...
OPC UA may be a complicated topic, but if you’re new to OPC UA, this article is the perfect starting point. Minimum requirements except for having the Peakboard Designer installed: Nothing! You can start right away, because we’re using an OPC UA server that is available to the public. Check...
We have discussed OPC UA extensively. It is one of the top five most used data sources with Peakboard, especially in factories and industrial environments. Most OPC UA values exchanged between Peakboard applications and OPC UA servers are scalar values that are mapped to one of the three Peakboard data...
Loyal long-time readers of this blog might remember an article from June 2023 about how to call OPC UA functions. Back then, we used an external OPC UA client called UaExpert to hunt down the right node ID and then wrote some LUA code to trigger the function on the...
