This communication system allows for a reduction in the cycle time of the machine. It also makes wiring easy and safe leading to a simple and quick start-up.

Selecting Models for Controllers and PLC CPUs

Based on the system size:

• The MELSEC iQ-R series is for medium to large-scale control.
• The MELSEC Q series is also for medium to large-scale control. This series introduced the idea of incorporating more than one CPU architecture.
• The MELSEC L series is for medium to large-scale control. It is baseless and, therefore, suitable for applications with limited space.
• The MELSEC iQ-F series is suitable for small-scale and stand-alone applications. This controller has amazingly high performance.
• The MELSEC iQ-R series is also for stand-alone and small-scale applications.

Models can also be selected while considering the control method as a decisive factor.
