February, 15, 2011 — Festo Introduces CPX-CEC CoDeSys Embedded Controller for use with its CPX series of multifunctional control terminals. CoDeSys is an IEC 61131-3 compatible programming environment. The controller benefits current users of IEC 61131-3, since they can port over their existing code, libraries, function blocks, etc., reducing programming time. New users can also benefit by the availability of six programming languages provided by CoDeSys, selecting one that is most comfortable for the programmer in a particular application. The CPX-CEC module provides machine builders with a means of overseeing all the units in a CPX terminal – regardless of whether they are for pneumatic or electric drives or I/O functions – using a fast, easy-to-program controller. Suitable for single and multi-axis applications, the CPX-CEC can operate autonomously or in conjunction with a host controller, such as a master PLC, and it can also be used as an intelligent slave in fieldbus-based systems to provide localized signal pre-processing. The CPX-CEC embedded controller is essentially a PLC in its own right, but with additional functionality. Based on a high performance 400 MHz low power consumption 32-bit processor, backed by 64 MB of memory, it features an Ethernet 10/100 Base-T interface for programming and host controller communications, and uses a backplane bus system to communicate with other modules in the CPX terminal. The controller has a cycle time of just 1 ms – making it one of the fastest on the market – and can be supplied configured as a fieldbus slave or as a CAN master for controlling other CANopen devices, such as electric drives. It supports all popular fieldbus protocols, including PROFIBUS, PROFINET, Ethernet/IP, DeviceNet, Modbus TCP, CANopen, CC-Link, and EtherCAT. Whereas most CoDeSys controllers are panel-mount or rack-mount designs, the CPX-CEC is a true embedded solution – all component parts are completely enclosed within the module, which carries an IP65/67 rating against dust and water ingress. The ability to deploy the CPX terminal and its constituent modules in the same environment as the machine itself – even on the machine if required – provides system designers with a very flexible solution for decentralized control.
