I/O Timing Charts
This section explains the I/O signals that are exchanged between the Controller and
external devices, and the timing charts for data output.
Measurement cycle: Standard mode (NORM)
T1:
Measurement cycle The measurement cycle is 1.5 ms.
T2:
Measurement processing time This is the time required until the measured data is applied.
(max. 1 ms)
T3:
Analog output response time This is the time until the Controller starts analog output after
completion of measurement. (100 µs)
T4:
IFU binary output response
time This is the time until the Interface Unit starts binary output after
completion of measurement. This time differs according to the
number of Controllers connected to each other. (0.5 ms x
number of connected Contr 0.5 ms)
T5:
Binary output cycle This is the time in which the Interface Unit outputs the binary data.
This time can be changed. (1 to 500 ms (default value: 1 ms))
T6:
GATE ON time This is the time that the GATE signal is ON. This time differs
according to the currently set binary output cycle. (binary
output cycle setting x 0.5)
This is the time that is required to capture data output
(measured values/judgment results) on external devices.
