Looking to get started with Structured Text / Structured Control Logic (ST / SCL)? Here’s an introductory guide to the PLC language that is not restricted to a single development…
The Variant data type is a special data type that accepts almost anything. Similar to the ANY data type, TIA Portal essentially creates a pointer to the data and passes…
There will always come a time in a project, where the compiling must be done. This is because you must compile in order to download to a PLC, even a…
Projects can never start early enough, and getting hardware early in a projects development is getting harder every day. This is why taking advantage of the Simulation PLC, built in…
Sometimes, you find yourself in a position where (despite no compilation issues) your PLC will just not start correctly. Instead of seeing the above image, with nice green ticks and…
Making changes to a project is an everyday aspect of PLC programming, especially during commissioning or fault fixing. When it comes to making changes, the key consideration should always be:…
As with all PLC environments, being “Online” is an important aspect. The difference between “Online” and “Offline” is that when your connected to a PLC and online, you are able…
A complete introduction to Ladder Logic programming, generalised for use in any environment
When developing new code, especially for a project that is still in development in other disciplines (such as electrical or process), not all of the information may be available This…
