Setting the Tolerance Comparator Value
This section describes how to read the tolerance comparator display, and its
setting procedure.
The Function of the Tolerance Settings
HIGH and LOW comparator tolerance values can be set. The measured value can be
displayed and output in 3 steps: when exceeding the HI comparator value (HI), when the value
drops below the LOW comparator value (LOW), and when the value is between the HI and
LOW comparator values (GO).
When the comparator output format is normal, the comparator output is as follows.
The comparator result of tolerance is outputted from the 12-pin I/O terminal block and the
expansion connector on the controller’s terminal panel.
