Siemens 6AG2516 Series PLC CPU, 3MB Program Capacity, 20 Inputs - 6AG2516-3FP03-4AB0

This plc cpu is a programmable controller module designed for industrial automation tasks, providing deterministic communication and programme execution within control systems. It integrates multiple fieldbus options for coordinated data exchange and supports structured programming languages for developing logic and control routines.

Features and Benefits:

• 3MB programme capacity enables complex control applications
• Supports PROFINET IRT for time-critical communication
• Embedded Profibus port allows legacy device integration
• 20 configurable inputs provide versatile signal acquisition
• 20 configurable outputs permit direct actuator control
• Operates from -40°C to 70°C for harsh environments

Applications

• Suitable for automated assembly line motion control
• Ideal for machine tool process sequencing and safety interlocks
• Used with distributed I/O networks in manufacturing plants
• Can be used for building management system integration
• Used for retrofitting systems that require Profibus connectivity

How many communication interfaces are available for network topologies?

There are three communication ports to connect PROFINET IRT, Profibus and additional network segments for flexible topology design.

Which programming languages can be used to develop control logic?

The unit accepts CFC, FBD, Graph, LAD, SCL and STL, enabling function block, ladder and structured textual development approaches.

What environmental standards and certifications does it comply with?

It meets a range of industrial standards including IEC 60068‑2‑38, EN 60721 classifications and directives covering hazardous substances and waste handling.

What packaging protection or rugged-design alternative is mentioned for harsher sites?

An IP67 alternative is noted as a comparable option for applications requiring enhanced ingress protection.

What thermal limits should be considered when installing in control panels?

The module is specified to function between -40°C and 70°C, so ventilation and ambient management should align with those limits.
