Ethernet technology is increasingly being utilized in the factory automation field to facilitate communications between computers and PLCs (programmable controllers). This has resulted in a growing need for Ethernet capability even in programable controllers with 10 to 200 I/O points used in small-scale control applications. The demand for Ethernet as an interface for programable controllers is also rapidly increasing in other fields such as in sewerage monitoring systems and building automation, in which scattered programable controllers in remote locations are monitored by computers through wireless and Ethernet networks.
The CP1L-EL/EM-type CPU units released today are programable controllers with built-in Ethernet ports enabling low-cost Ethernet connection and designed to meet a wide variety of Ethernet connectivity needs in a wide range of fields.
The ability to send and receive messages means it is possible for a host computer to monitor the status of controllers and also receive feedback from the controllers about any onsite abnormalities they detect. The controllers also feature socket communications capability meaning it is possible to connect them with a wide variety of Ethernet-enabled control equipment.
The added function block memory (10K steps) improves reusability of user program assets and supports design standardization. The function blocks aid efficient creation of reusable programs used in various devices such as ladder programs used for Ethernet communications.

All the CP1L-EL/EM-type CPU units incorporate two analog inputs meaning that stand-alone CPU units can handle various applications such as monitoring for fluid level detection. For applications that require more than two analog inputs, up to six analog inputs and four analog outputs can be controlled by mounting analog option units without the need for an expansion unit.
