6-2-7 DAV output
The DAV output is the measured value in digital format, converted to an analog output voltage.
A DAV output mode can be selected from output without holding or output after holding in function
mode
f-24
. Scaling is available in function modes
f-22
and
f-23
.
6-2-8 BCD parallel output
The BCD parallel output is the measured value converted into a BCD format. The output logic can
be selected from positive or negative in function mode
f-32
. An output rate can be selected from 1
time/s, 10 times/s, 100 times/s, 1000 times/s or 2000 times/s in function mode
f-33
.
6-2-9 Comparator and comparator output
The comparator judges the measured values using the upper/lower limit values and the comparator
output outputs the comparison results.
A comparator mode can be selected in function mode
f-16
.
A zero band setting can be selected in function mode
f-17
.
The comparator has a comparator hysteresis function and the values used can be set in function
modes
f-19
to
f-21
.
6-2-10 Modbus RTU
The AD-4532B has Modbus RTU protocol. The values that the AD-4532B indicates and the
AD-4532B status can be read and the set values of the AD-4532B can be written, using Modbus
RTU.
This is used, for example, to read measured values or change the settings when connecting the
AD-4532B to a personal computer, PLC or programmable display
