Commissioning
Ch1/Ch2 CycleCount and Ch1/Ch2 Value
Each EL4732 record contains a CycleCounter for each channel that is incremented with each record, and n
analog measured values with a width of 2 bytes each. With an oversampling factor of n = 25 a record
therefore consists of a 16-bit CycleCounter (overflowing) and 25 16-bit samples per channel. The
CycleCounter in the higher-level control system can be used to verify the consistency of the record transfer.
By default the EL47xx is set to n = 1, resulting in the process image shown in Fig. TwinCAT tree EL4732.
WcState 0/1 (Online tab)
Boolean variable indicating the working counter status of the terminal. An invalid working counter (value: 1)
is displayed if the EtherCAT slave with its EtherCAT slave controller (ESC) did not read or write process data
from or to the EtherCAT frame read.
