Table 110: Technical Data EtherCAT Slave Protocol
Note:
* The loadable firmware supports for the number of cyclic input data
and for cyclic output data in total up to 512 bytes. If more than 256 bytes
for input data or for output data shall be exchanged via EtherCAT, then a
customer specific XML file is necessary. Additionally the following formula
applies: (number of input bytes + 3) / 4 + (number of output bytes + 3) / 4
must be less or equal to 128.
