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 "P P P P " relative address: 0005H, Data number: 03H
