Measured value, measured value time stamp, device status, measured value
status
The registers for storing the measured value, measured value time stamp, device status,
and measured value status are shown below.
The values of these registers are updated according to the data acquisition interval.
Data acquisition interval Register update interval
1 ms 10 ms
10 ms 10 ms
50 ms 50 ms
100 ms 100 ms
Two types of register assignments are available to simplify accessing of accessing
registers.
・
Continuous reading of measured values (Table 1): Placement of registers by which
measured values and statuses are respectively continuous.
・
Reading of measured values and statuses by individual channel (Table 2):
Placement of registers by which measured values and statuses can be acquired as
a set.

40101 0064
Measured value time stamp
R
The time of measured values
can be read.
This setting is common to all
channels.
The coordinated universal time
or UTC can be read as a 64-bit
unsigned integer.
40102 0065 R
40103 0066 R

40105 0068 Device status R
The device status of the VZ20X
can be read.
40106 0069
CH1 measured value
R
Measured values can be read
as 32-bit signed integers.
The range changes depending
on the input range.
