====== Hardware points ======

As of Mervis IDE 2.3.0.x, for the FreeRTOS platform there is load evaluation as HW points (which is just a measure of processor and memory load, these hardware points have nothing in common with physical data points - inputs and outputs). The HW points add with added channels and devices. After compilation, the HW points utilisation is listed in the Output tab.

If the maximum recommended amount of HW points is exceeded, the warning can be ignored by checking Ignore points in PLC properties, and redeploying the project. However, for correct and safe PLC operation, this is not recommended. The PLC may lack resources for other processes, and e.g. web server response may be worse.
