So what does a CODESYS Based Sparkplug B Node cost?
This FAQ acts as a guideline for costs per node usage for home use. Costs are indications based on maker and home grade hardware and industrial software license components.
If you wish to use our Sparkplug for CODESYS library in a real industrial environment, no problem, you only need an industrial PLC/PC hardware platform as the base software is allready industrial grade.
Though our library is for the larger part open source, we still make use of the Single License (SL) industrial IoT bundle component to guarantee MQTT stability. Luckily this library offers excellent value for money! It has an amazing assortment of filehandling and communication protocol suites. Especially if you take into consideration that you can use all provided software components from the IIoT Bundle library SL and the Runtime SL for your individual use immediately.
So what will it actually cost?
Every Node needs a hardware platform of choice. Here we chose a Raspberry Pi 3B (any model could do) as it is very popular and powerful, starting at 12 Euro. Search the web for a starter kit. Maybe you can pick up a good deal. We obtained a 3B for 35 euro.
Optional USB license storage key (dongle) is recommended
It is recommended to spend a little extra on the optional usb license storage key and activate your runtime and library licenses on it. Wait for your key to arrive, and activate the license on them, plug it in your hardware -> READY!
Benefits of the USB license storage key
Protects your license against loss,
Enables you to migrate your licenses as the licenses are bound to this USB key and not to the Raspberry Pi
If you choose the soft-container please take in account the following
Migration of your license is not possible after activation as soft containers are hardware bound! So if your raspberry pi breaks or you want to migrate, you have to buy a new license.
If your SD Card gets corrupted you have a bigger chance of losing the license on which the soft container resides.
There is a procedure for this, but a dongle just makes life easier. The choice is yours.
In the end it all depends on the chosen hardware, but for around 160 Euro we have a very powerful and highly scalable PLC based on Raspberry Pi 3B hardware for home educational and lab purpose. It can act as a programmable gateway for all your (wireless) home automation and is more then capable of running CODESYS Sparkplug Primary Host node or a Edge Node (or both at once).
