Product Details

Modicon S929-000 is a premium multi option processor serving as the core plc cpu module for the classic Modicon 984X automation rack. This legacy control spare is highly sought after for maintenance and retrofit of obsolete control systems. The multi option processor executes ladder logic programs, manages local and remote I/O scanning, and supports high-speed S908 remote I/O communication links to connect distributed field stations. It retains user logic and register data with reliable memory, minimising production downtime when replacing failed original controllers. This plc cpu module fits the dedicated Modicon chassis and works with compatible I/O and communication cards to rebuild a complete industrial control system.

Basic Parameters

Brand: Modicon

Model: S929-000

Product Type: Multi Option Processor / PLC CPU Module

Compatible Chassis: Modicon 984X series rack

Network Support: S908 Remote I/O bus

Programming Language: Ladder Logic

Mounting: Rack mount

Product Status: Discontinued legacy spare

Net Weight: Approximately 2.1 kg

Supported Functions

This multi option processor supports program upload, download and modification, high-speed I/O scanning, register data storage and S908 RIO network communication. It runs built-in self-diagnostics to detect bus errors, communication interruptions and module faults. The plc cpu module supports sequential control, interlock protection, arithmetic operations and expansion of multiple remote I/O nodes to satisfy complex process control demands.

Core Functions

As the central processing unit, this multi option processor runs all user control logic, processes incoming field signals and generates corresponding output commands. It maintains stable scan cycles and governs the S908 remote I/O network for distributed signal exchange. This legacy control spare acts as a direct drop-in replacement to quickly restore full functionality for ageing Modicon automation racks.
