• In a multiple CPU system, the module name can also be read by specifying the module controlled by the CPU module of
another CPU.
• In the following program example, when M0 turns on, the module name of the module mounted at I/O number 0020H is
stored in D0 and later.
M0
• Module having a module name (example: RJ71GP-SX)
PW CPU
Start I/O number: 0020H
• Module having no module name (example: RX40)
PW CPU
Start I/O number: 0020H
• Empty slot
PW CPU
Start I/O number: 0020H
