Schneider Modicon M258 Plc

Many machines operate on several coordinated axes, exchange information with other higher-level systems and yet have a controller that must fit within a small panel. Schneider Electric's Modicon M258 PLC is designed specifically for motion-based automation projects that require a combination of speed of processing, communication capabilities and flexible I/O interfacing without impacting cycle time. Perfect Automation & Innovation supply this controller for motion-based control projects that combine logic control and drive and positioning integration.

The internal Ethernet architecture allows for direct connection of HMI, SCADA and remote I/O reducing the need for additional communication modules. The high-speed execution of tasks enables effective management of cam profiles, synchronous transport system conveyor sequencing, packaging sequences and dynamic interlocking. In addition, the available memory will store the motion parameters, alarm history and production data without affecting scan performance.

Both servo and stepper applications benefit from integrated pulse outputs and encoder interfaces, enabling precise positioning. When needed, expansion modules can be added for digital, analog, and safety I/Os in accordance with machine application requirements, enabling structured panel layouts that facilitate service. Clear separation of the power and signal wiring in the control panel assists the controller's stable operation in electrically noisy industrial environments.

Clearly identifiable addressing/terminal arrangements simplify the commissioning of PLC systems while making it easy for maintenance personnel to troubleshoot. PLC systems have many applications in automated packaging machines, printing machines, material-handling systems, automated assembly lines, and other customised machines that are dependent on the following: Coordinated motion control; fast-response times; Reliable communications, all of which contribute to production consistency and machine uptime.
