All signals in the following charts are in the negative logic (ON at LOW signal, as factory set).

• Timing Chart for Single Sampling Cycle Data Output
• Output is provided via open collector, enabling wired-OR gate configuration When one of REQ signals (REQ, MAX_REQ or MIN_REQ) is given and its width is between 20 and 50 ms, DATA is established and DAV output is given in approx. 30 ms from the falling edge of the REQ signal. Read in the data to a PLC at the timing of the DAV output signal. DAV is turned off in 40 ms. DATA is turned off in 16 ms after that. When DATA output logic is negative, wired-OR connection is available for BCD data, POL, OVF, HH, H, P, L and LL signals. Measured data is output every 64 ms while one of REQ signals (REQ, MAX_REQ or MIN_REQ) remains ON. For Event trigger modes, the data value is the same as the display.
