3.2 Setting Pulse Output
3.2.1 Selection of Measurement Item for Pulse Output
[Procedure]
(1) Write a measurement item for pulse output value to the D register in the table below.
The data type is integer.
(2) After writing that value, write 1 to the pulse output writing status register, D0211.
D Register
D0208
D0211
Reference No.
40208
40211
H No.

00D2
Description
Measurement item for
pulse output
Pulse output writing status
(D0208, D0209, and D0210
are validated)
Effective Range
0: Active energy
1: Regenerative energy
2: LEAD reactive energy
3: LAG reactive energy
4: Apparent energy
If other than 1: Invalid
If 1: Writing is executed
Initial value of measurement item for pulse output: 0 (active energy)
[Example]
To set the measurement item for pulse output to 1 (LEAD reactive energy):
For station number 01, use PC link communication (without checksum) and the random
write command as shown below:
[Command]
[STX] 01010WRW02D0208, 0001, D0211, 0001 [ETX] [CR]
[Response]
[STX] 0101OK [ETX] [CR]
NOTE
• A measurement item for pulse output value can be set for the PR300 with pulse
output.
• When the PR300 is the three-phase four-wire system (2.5 element), the following
measurement items can be measured only when the current is in a state of equilib-
rium:
“2: LEAD reactive energy”, “3: LAG reactive energy” and “4: Apparent energy.”
