Programming Examples
This chapter presents some detailed examples of 1775–KA module
commands and message procedures.
The first set of examples shows individual commands that could be
programmed directly into a PLC–3 message (MSG) instruction. Figure
8.1 illustrates the differences in reading and writing data between two
PLC–3 stations. Figure 8.2 shows how to write different types of data to a
remote PLC–3 station. Figure 8.3 shows how to write different types of
data to a remote PLC or PLC–2 station.
