When choosing the power supply module, the total power consumption of the I/O modules, of
the special function modules and of the peripherals must be taken into account. If necessary,
an extension unit with a further power supply module should be used.
When wiring large plants or for machines with modular configuration, remote inputs and out-
puts (Remote I/O stations) which are situated on site offer many advantages. Thus the connec-
tions between inputs/outputs and sensors/actuators can be kept short. To connect a remote
I/O station and the system with the PLC CPU only a network module and a network cable is
required. Depending on the selected CPU type up to 4096 local (on main and extension base
units) and up to 8192 remote I/O points can be addressed.
Load Distribution with Multiple PLC CPUs
Multiple PLC CPUs of the MELSEC System Q can be used together to allow a single system to
exercise controls that are different in tact time, e.g. sequence control and data processing.
Thus sequence control and data processing can be distributed to different CPUs.
