Numeric functions

This group of the standard blocks provides standard →functions according to the →IEC-standard with numeric →variables (example: natural logarithm, cosine) as well as arithmetic functions.

No check of invalid connections

For some blocks, invalid connections are not checked by Neuron Power Engineer. Therefore, enter code in your application to detect invalid connections (e.g. IF-statements in the ST-code). Example: An invalid connection occurs during a calculation using a standard block. Giving you a specific example: Calculating -250.5 by means of the EXPT-block is an invalid connection.
Invalid connections of blocks that are checked by Neuron Power Engineer are listed in the description of the corresponding block.

See "Standard blocks for the application" for information what the consequences of an invalid connection might be.

Moreover, observe the effects of the compiler settings on the accuracy and behavior of mathematical functions.
