Product Details

Modicon AS-584L-231 is a high-capacity plc processor and complete controller assembly belonging to the classic Modicon 584L programmable controller family. This legacy cpu module is designated as Level 2 with 32K memory, built to run complex ladder logic for process and machine automation. As the central brain of the 584L rack, the plc processor scans local and remote I/O, executes user control programs, and communicates with HMI and host monitoring systems. It retains program and register data with reliable memory storage, minimizing downtime during unexpected power cycles. This controller assembly is a discontinued legacy spare, widely used as a drop-in replacement to restore full control capability for ageing Modicon 584L automation racks without wholesale system upgrades.

Supported Functions

This plc processor supports ladder logic upload, download and modification, continuous I/O scanning, register data storage and serial communication for supervisory control. The controller assembly performs built-in self-diagnostics to detect bus faults, communication failures and internal hardware errors. This legacy cpu module supports sequential control, interlock logic, mathematical operations and expansion of remote I/O nodes to satisfy demanding process control requirements.

Core Functions

As the primary controller assembly, this plc processor executes all user logic, converts incoming field signals into output commands and maintains stable scan cycles for the entire rack. It manages communication links to exchange real-time data with upper monitoring devices and remote I/O stations. This legacy cpu module serves as a direct spare to bring offline 584L control racks back into reliable operation.
