Warning Status Area
Used with each of the hold functions (peak, bottom, top, and valley) to control the execu-
tion timing of hold functions from the Master.
Analog Output Units support one type output data. Allocate the required data
as shown in the following tables.
Used to allocate analog output data.
An Analog I/O Unit has two internal Status Areas. Bits are set with respect to
thresholds set by the user for each function. When any bit turns ON in one of
these Status Areas, the relevant Communications Unit Status Flag turns ON.
The Master Unit is notified of the status of Communications Unit Status Flags.
Information in I/O Unit Status Areas can be read using the Setting Tool.
