•In the following examples a and b are LREAL variables
•“b := 3 / 2 * a” is the same as “b := a”
•a*a*a is several times faster than a**3
•a * 0.5 is faster than a / 2.0
•Access to the process image (IOs) causes swapping of the data
•CASE… OF… compares with all values from top to bottom until
the result is true
•Using constants is much faster than using static variables

•OpenUser-Communication (e.g. TCP/IP)
•PG communication (TIA Engineering)
•Web communication
•Acyclic communication
•OPC UA communication
•Interpolation of cam disks
Affects of communication load
•Communication task is started every 1 ms
•Communication load can catch up lost
