Examples Of Di/Do Connection - Mitsubishi Electric MELDASMAGIC64 Connection Manual

5.5.7 Examples of DI/DO Connection

There are two types of MELDASMAGIC64 DI/DO; the base I/O unit and remote I/O unit. Normally, one
base I/O unit is used, a remote I/O unit is connected to RIO1 or RIO2 (for future expansion), and the No.
of I/O points is configured in combination with the user specifications.
Refer to "7. Remote I/O Unit Connection" for information about remote I/O units.
