In recent years, there has been increased demand for more advanced functionality, even in micro PLCs with approximately 10 to 200 I/O points for use in small-scale control applications. Since 2006, CPU units for advanced micro PLCs, the CP1H CPU units and CP1L CPU units, have been added to the CP series.
There are also many manufacturers that give greater priority to cost efficiency and want to achieve the same functionality while reducing materials costs. This represents a major demand for price reduction. The CP1E CPU units released today can be used to build low-cost micro PLCs that respond to these demands.
Manufacturers that produce compact equipment place importance on keeping manufacturing costs down without spending an excessive amount of time on design and system implementation. The CP1E CPU units also respond to this demand by featuring simplified programming and wiring verification.
There are two types of CPU units: the low-cost, minimal functionality E-type basic CPU units, and the N-type application CPU units, which incorporate a serial port for connection with programmable terminals and a pulse I/O function for position control. The N-type CPU units can control compact devices efficiently.
