Siemens 6ES7 313‑6CG04‑0AB0

Built‑in Digital Input / Output Processing Integrated 16‑channel 24VDC digital inputs and 16‑channel digital outputs. Directly collect field switch signals, sensor status; output switching signals to control relays, contactors and solenoid valves without adding extra I/O modules for small‑scale systems.
Embedded High‑speed Technological Functions Provide 3‑channel 30 kHz high‑speed counters. Support encoder signal acquisition, pulse measurement, frequency counting and speed monitoring, suitable for motion‑related control tasks such as positioning and speed tracking.
Multi‑interface Industrial Communication Equipped with MPI multi‑point interface and PROFIBUS‑DP master/slave interface via RS‑485 physical layer. Realize data exchange with HMI, other S7‑300 PLC stations, distributed DP slaves and variable‑frequency drives; build distributed I/O control system.
System Diagnosis & Fault Handling Support rich system interrupt organization blocks. Detect module hardware failure, I/O channel abnormality and communication error. Store fault diagnostic information, report alarms to upper‑level system for equipment troubleshooting and predictive maintenance.
Memory & Hardware Feature 128 KB integrated work memory. Program and data must be stored on external MMC card. 24 VDC power supply, mounted on S7‑300 U‑rack; 40‑pin front connector is required for field wiring.

Stand‑alone Compact Machine Control: Control small‑and‑medium‑size machinery, assembly equipment, packaging machines and material handling devices. The onboard I/O and high‑speed counters reduce cabinet hardware quantity for compact machine solutions.
Distributed Automation System: Work as PROFIBUS‑DP master station to connect remote DP I/O modules, inverters and field devices, implement field‑bus‑based distributed control on production lines.
General Factory Automation: Widely used in workshop production equipment, process auxiliary control units, test benches and old‑site renovation projects. It can work as main controller or spare replacement part for existing S7‑300 automation systems.
System Note: S7‑300 product family is phased out by Siemens. This CPU is mainly supplied as maintenance spare part for existing running plants, and new projects tend to adopt S7‑1500 series instead.
