408 408  The time of A/D conversion is 240ms for each channel. When “3" (unused) is set for a channel, this channel would not have A/D conversion, therefore, the total time for conversion decreases. In the above example, the conversion time is as follows:
409 409

BFM #187 is used for the dead zone of alarms 1 to 4 for CH4. When the measured value (PV) is near the alarm set value, the alarm status and the non-alarm status may be repeated by fluctuation in input area. In this case, setting the alarm dead zone could avoid the repeating of the alarm status and the non-alarm status.
