EtherCAT master: number of cyclic data

The EtherCAT master app is limited by:

  • Max. number of devices
  • Max. number of cyclic input data of the master
  • Max. number of cyclic output data of the master

Is there any way to check the amount of input/output data in an offline configuration?

Is it known when these limits will be increased for the X7?

You can check all licensed software metrics like utilized IO data via the corresponding tab in the device data in the ctrlX PLC Engineering online and offline:

The current features can be found in our online documentation "EtherCAT Master – Features".

The numbers for ctrlX CORE X3 stay the same in the future. For ctrlX CORE X7 the input and output data combined was increased to 10kB from version 2.02 as the sum is the value that counts. The number of slaves will be increased next year.
