Description
Pulse unit
Pulse output writing status
(D0208, D0209, and D0210
are validated)
Effective Range
1 to 50,000
Unit:
ϫ 100 Wh/pulse
If other than 1: Invalid
If 1: Writing is executed
Initial value of pulse unit: 10 (1000 Wh/pulse)
[Example]
To set the pulse unit to 100 Wh/pulse, write “0001.”
For station number 01, use PC link communication (without checksum) and the random
write command as shown below:
[Command]
[STX]01010WRW02D0209,0001,D0211,0001[ETX][CR]
[Response]
[STX]0101OK[ETX][CR]
NOTE
• A pulse unit value can be set for the PR300 with pulse output.
• To set the pulse unit value via communication, set it to 1/100 the value of the displayed
(true) value (e.g., set it to 5 when setting the pulse unit value to 500 Wh/pulse).
