Chapter 2 Specification of Communication port for CPU module

2 – 37

2.3.2 Dedicated port

The specifications in setting the serial communication port as a dedicated port is shown in the table 2.21.

In the dedicated port, a CPU program can be created or monitored from the programming device connected. Also, a

monitoring system which uses a monitor available on the market can be constructed. Moreover, a variety of

systems can be constructed by connecting a personal computer and creating software.

For setup and setting the connecting cables, please check beforehand whether it is used as the purpose.
