The data is set in approximately 30 ms from the rising edge of the
REQUEST signal and the DATA VALID signal is output.
When reading the data from a Programmable Controller, start
reading the data when the DATA VALID signal turns ON.
The DATA VALID signal will turn OFF 40 ms later, and the data will
turn OFF 16 ms after that.
Measurement data is output every 64 ms while the REQUEST signal
remains ON.
Note: If HOLD is executed when switching between data 1 and data
2, either data 1 or data 2 is output depending on the timing of
the hold signal. The data will not go LOW.

Note: The BCD output connector pin number is the D-sub connector pin number when
the BCD Output Cable (sold separately) is connected. This number differs from
the pin number for the Digital Indicator narrow pitch connector (manufactured by
