NumericEnh functions

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

No check of invalid connections

For some blocks, invalid connections are not checked by logi.CAD 3. Therefore, enter code in your application to detect invalid connections (e.g. IF-statements). Example: An invalid connection occurs during a calculation using an IEC-block. Giving you a specific example: Calculating -25^0.5 by means of the EXPT-block is an invalid connection.
Invalid connections of blocks that are checked by logi.CAD 3 are listed in the description of the corresponding block.

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

logi.CAD 3 supports the following numeric functions as enhancement to the IEC-standard:
