Table 67: Technical Data EtherCAT Slave Protocol
Note for NJ 100XX-RE: * 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: The sum of the input data length and the
ouput data length may not exceed 512 bytes, where each length has to be
rounded up to the next multiple of 4 for this calculation.
