18.7.2 Sender
The variables H208 and H209 are transmitted cyclically every 10 ms to another inverter.
The values of H208 and H209 can be changed using input DI17.
DI17 = 0: H208 = 111111 / H209 = 222222
DI17 = 1: H208 = 222222 / H209 = 444444
Task 2 is not implemented in this sample program.
/*=========================================
Variables H208 and H209 are sent cyclic
every 10 ms to another inverter via SBus.
The values of H208 and H209 can be altered
with input DI17.
DI17 = 0: H208 = 111111 / H209 = 222222
DI17 = 1: H208 = 222222 / H209 = 444444
