Analog Output Units support one type output data. Allocate the required data
as shown in the following tables.
Output Data
5-2 Status Areas
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.
GRT1-AD2
Warning Status Area The Analog Input Unit’s Warning Status Area is configured of the following 16
bits. The Warning Status Area provides notification of minor errors detected in
the Unit.
I/O data Details
Hold Flags (1 output byte) Used with each of the hold functions (peak, bottom, top, and valley) to control the execu-
tion timing of hold functions from the Master.
Data Type Details
Output data (4 output bytes) Used to allocate analog output data.
