INPUT DATA AREA
The following table lists the input area registers (prepared by the instrument and read from the master),
common to all PROFINET, ETHERCAT, ETHERNET/IP fieldbuses. The registers have a size of 16 bits.
The input area is updated to a maximum frequency of 90 Hz (60 Hz for PROFIBUS fieldbus). The size
of the Input area set in the fieldbus master must coincide with the dimension set in the instrument.
