For the programmable devices from the controller family
ecomat
mobile
numerous functions are
available which enable use of the devices in a wide range of applications.
As these functions use more or fewer system resources depending on their complexity it is not always
possible to use all functions at the same time and several times.
NOTICE
Risk that the controller acts too slowly! Cycle time must not become too long!
►
When designing the application program the above-mentioned recommendations must be complied
with and tested. If necessary, the cycle time must be optimised by restructuring the software and
the system set-up.
It must also be taken into account which CPU is used in the device.

The higher the CPU frequency, the higher the performance when complex functions are used at the
same time.
