4.3.5 Status information (14-bit mode)

With the analog output unit, the following information can be monitored in the external input
area WX.
 Status information
I/O No. Description
X20 Analog output unit power
X21-X23 Used in the system
X24 CH0 data writing status
X25 CH1 data writing status
X26 CH2 data writing status
X27 CH3 data writing status
X28-X2F Used in the system
X30-X33 CH0 range setting state
X34-X37 CH1 range setting state
X38-X3B CH2 range setting state
X3C-X3F CH3 range setting state
(Note 1):As output data and the output switching flag are allocated to the same I/O, a data error is detected correctly
only when a digital input value is within (K-8192 to K8191) for the ±range and (K0 to K16383) for the + range. In
the case of digital input values exceeding these ranges, data may be converted without an error, so always
insert a program which checks the upper and lower limits.
(Note 2):In the 14-bit mode, the range setting state of each channel specified in WY2 and WY3 can be confirmed.
0:OFF, 1:ON、
0:Normal, 1:Error (Note 1)
An error occurs when data written to the memory area (WY2/WY3) is
out of each range, and the data conversion is not performed. The
error is cleared when data within the range is written and the
conversion is performed.
The state of a specified output range can be monitored. The following
constants are stored for each range.
H0: -10V to +10V, 0mA to 20mA
H1: -5V to +5V,4mA to 20mA
H2: 0V to 10V
H3: 0V to 5V
Same as above.
