Un\G45)
(1) For each channel, the maximum and minimum values of the converted digital values
are stored in this area every sampling time in 16-bit signed binary.
(2) The stored values for all channels will be cleared to 0 when the operating condition
setting request (Y9) is set to ON and the setting is changed or when the maximum
value/minimum value reset request (YD) is set to ON.
(3) For the channel where averaging processing is specified also, the maximum and
minimum values of the digital values from sampling processing are stored in this area.
(4) When the scaling function is enabled, maximum/minimum values after scaling
conversion are stored.
3.4.11 Input signal error detection extended/input signal error detec-
tion setting (Un\G47)
(1) This area is used to set whether the input signal error detection, process alarm, or
rate alarm will be enabled or disabled for each channel.
If the warning of input signal error detection is enabled, the input signal error detection
can be performed by setting the same value of upper and lower limit or different value
of upper and lower limit.
(2) To validate the input signal error detection extended/input signal error detection
setting, the operating condition setting request (Y9) must be turned ON/OFF. (Refer to
Section 3.3.2.)
(3) All channels for the input signal error detection and all channels for the input signal
error detection extended setting are set to the same value of upper limit and lower
limit as the default setting.
