Hold Flags (1 output byte)
Analog Input Terminals and Temperature Input Terminals support the follow-
ing five types of input data (three of which are Status Flags), and one type of
output data. The required data can be allocated in the Master either individu-
ally or in combination with other data.
• Used to monitor analog data or temperature data.
• Select one type of data from analog/temperature input value,
peak value, bottom value, top value, valley value, or rate of
change. (Default allocation: Analog or Temperature input value)
Note The comparator can be used with Analog Data 1 or Temper-
ature Data 1.
• Used to monitor other data at the same time as the data allocated
to Analog Data 1 or Temperature Data 1.
• Select one type of data from analog/temperature input value,
peak value, bottom value, top value, valley value, or rate of
change.
Note The temperature difference detection function can be used
to detect differences between the value in an input word and
Temperature Data 2.
Used to allocate the Network Voltage Monitor Flag, the Unit Con-
duction Time Monitor Flag, and the Cumulative Counter Flag.
Top/Valley Detection Timing Flags are allocated in one word. These
flags are used to time reading the values held as the top and valley
values when both the top and valley values are allocated at the
same time.
Used to allocate the bits for the Comparator Result Flag, Top/Valley
Detection Timing Flag and Off-wire Detection Flag. The function of
each bit is as follows:
• Comparator Result Flags
Allow control of the judgement results only, without allocating
analog values
• Top/Valley Detection Timing Flags
Used to time reading the values held as the top and valley values
when both the top and value values are allocated at the same
time.
• Off-wire Detection Flags
Disconnections can be detected even when the analog values are
not allocated.
Note Always set the connection path with the Configurator when the display mode
is set to 1/100 display mode on the Unit's DIP switch. If the "normal display"
I/O data is selected with the configurator, the temperature data allocated in
the I/O data will be 0.
Used with each of the hold functions (peak, bottom, top, and valley)
to control the execution timing of hold functions from the Master.
