CHAPTER 6 ASSIGNMENT II (FIXED BUFFER COMMUNICATION BETWEEN PLC
CPUS (PROCEDURE EXIST))
In this assignment, the exercise of the fixed buffer communication (procedure exist)
function is performed.
The PLC A side sends data and the PLC B side receives data.
6.1 System Configuration of Exercise
The following shows the system configuration for the exercises in Assignment II.
In Assignment II, data are communicated using the TCP/IP communication, and the
device (X) of the PLC CPU on the sending side is monitored using the demonstration
machine on the receiving side.
Although 10 PLC CPUs are connected to the Ethernet, the communication is made
only between the PLC CPUs which have the same demonstration machine No. in
Assignment II.
