further information, see the Manual MasterTool IEC XE – MU299609 to verify the availability of

some characteristic in a specific product version.

Performance

The Nexto Series CPU performance relies on:

 User Application Time

 Application Interval

 Operational System Time

 Module quantity (process data, input/output, among others)

Application Times

The execution time of Nexto CPUs application depends on the following variables:

 Input read time (local and remote)

 Tasks execution time

 Output write time (local and remote)

It is important to stress that the execution time of the “Main Task” will be directly influenced by the

“Configuration” system task, a task of high priority, executed periodically by the system. The

“Configuration” task may interrupt the “Main Task” and, when using the communication modules, as

the Ethernet NX5000 module, for instance, the time addition to the “Main Task” may be up to 25%

of the execution average time.
