(8)PC link protocol transmission program
This section presents a sample program that uses PC link protocol transmission.
This program creates increment data within the local station and writes it to the remote station's registers. Next it reads out the same area and compares it with the data within the local station to check that the function succeeded.
Remarks
Make a point of understanding the content before writing programs that use the S20LP- station. The sample programs present basic examples of
