- Page 83 Technical equipment of TC600 PLC Period cons2 Frequency ;frequency = 1 / period Phase shift Measurement of the phase shift is used for signals with the same fre- measurement quency. The time difference between descending edges of two different sig- nals connected to inputs DI1 and DI0 of BM is measured.
