Example of Transmitting a Message (Internal Calculation Data)
The message is composed as follows when writing the following PID parameters to station number 1.
P = 100.0 (= 1000D = 03E8H)
I = 10 (= 100D = 0064)
D = 5.0 (= 50D = 0032H)
•Parameter “PP
PP
” relative address: 0005H, Data number: 03H
Point
The decimal point cannot be included in the sent data, so data such as “100.0” above is sent as “1000”.
Refer to
For each type of send data format, see “Chapter 7, Address
Map and Data Configuration” (p. 39).
