Output Data
Analog Output Slave
Units (CRT1-DA02)
Analog Output Slave Units support one type of output data.
Output Data
Use the CX-Integrator to allocate I/O.
6-2 Status Areas
An Analog I/O Slave Unit has two status areas: the Warning Status Area and
the Alarm Status Area. The status flags in these areas are turned ON and
OFF based on the threshold/monitor values set for each function in that Unit.
If any flag in the Warning/Alarm Status Area in the Analog I/O Slave Unit turns
ON, the corresponding status flag in the Master Unit to which the Slave Unit is
connected turns ON. Bit 12 in the Master Unit corresponds to the Warning
Status Area and bit 13 corresponds to the Alarm Status Area.
The Analog I/O Slave Unit's status area information can be read by using the
CX-Integrator or explicit messages.
Analog Status Flags
(4 input bytes) Used to allocate the bits for the Comparator Result Flag,
Top/Valley Detection Timing Flag, and Disconnected Line
Detection Flag. The function of each bit is as follows:
• Comparator Result Flags
Allow control of the judgement results only, without allocat-
ing 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.
• Disconnected Line Detection Flags
Disconnections can be detected even when the analog val-
ues are not allocated.
Analog Data +
Top/Valley Detection
Timing Flags (10
input bytes) The Top/Valley Detection Timing Flags (2 bytes) are allocated
following the Analog Data (8 bytes).
I/O data Details
I/O data Details
Hold Flags (2 output
bytes) Used with each of the hold functions (peak, bottom, top, and
valley) to control the execution timing of hold functions from
the Master Unit.
Data Type Details
Output data (4 output
bytes) Used to allocate two words of analog output data.
