Most embedded systems will need to interface with “reality” in some way, whether that is reading in information measured by transducers or controlling some “actor” device to achieve some action. In the case of the Harting MICA, it has eight GPIO lines which can be used for this purpose.   Working with GPIO The Harting MICA includes eight lines of GPIO on the I/O connector, including four high-side drivers, two low-side drivers and two configurable drivers. These line ...
In industrial applications, equipment can often suffer harsh conditions. While some of these are more obvious (e.g. temperature extremes, vibration, liquid and dust), others are less obvious such as power issues. In this part, I run some automated tests to try and determine just how much power the Harting MICA consumes and how it behaves when faced with different voltages.   Voltage Tolerance & Power Consumption To understand the tolerance of the Harting MICA to various voltages and det ...
One of the key features of an “industrial” piece of equipment is its tolerance to environmental extremes. This includes extremes of temperature, vibration, dust and liquid ingress. In this section, I try to kill ‘n+1’ birds with ‘n’ stones by trying to use the Harting MICA as a weather station, condition monitoring solution and then try to take it for a swim.   Data Handling While the Bosch CISS sensor is happy to stream data continually, to perform this ...
While the Harting MICA may be the main start of this RoadTest, it’s also important to take a good look at the Bosch Connected Industrial Sensor Solution (CISS) as it is in itself a separate product which has capabilities beyond that exposed within the present version of CISS Gateway.   Bosch CISS As mentioned earlier, the Bosch CISS is an IP54-rated puck-shaped device incorporating six sensors (Accelerometer BMA280, Gyroscope BMG160, Magnetometer BMC150, Temperature sensor, Humidity s ...
The datasheet for the Harting MICA CISS Complete IIoT Starter Kit makes a fairly bold claim – that you could be up and running with a condition monitoring system in just 10 minutes. Let’s put this to the test. In this rather long chapter, I will be examining the setup process, software available, hardware, documentation and troubleshooting experience.   Initial Setup As all the necessary components are included in the kit, getting started is a matter of plugging everything in an ...
In this section, I will be covering the unboxing experience – in the case of the Harting MICA, it’s a delight of its own which is well worth looking at.   Unboxing The kit from Harting comes sealed in shrink-wrap for freshness. The design of the box art is very clean, featuring a mostly black, white and yellow scheme. The top of the box labels the unit is as the Harting MICA CISS Complete IIoT Starter Kit with an image of the unit and sensor. The bottom of the box is blank, ...
In this blog post, I’ll provide a little background on the industrial internet-of-things and the various products on the market today.   IoT vs IIoT – Same, but Different Unless you’ve been living under a rock, you’ll probably have been seeing the internet-of-things (IoT) revolution currently sweeping through the consumer space. This includes things like internet-connected Smart TVs, fridges, doorbells, light globes, thermostats and cameras just to name a few. It see ...
