Siemens CPU 313C 6ES7313-5BE00-0AB0 S7-300 Compact Module

SIEMENS 6ES7313-5BE00-0AB0 SIMATIC S7-300 CPU 313C Compact CPU

The SIEMENS 6ES7313-5BE00-0AB0, also cataloged as the 6ES7313-5BE00-0AB0 CPU 313C, operates as a compact central processing unit with integrated digital and analog I/O, fast counters, and MPI communication executing user logic within SIMATIC S7-300 platforms.

Hardware Specifications

Integrated I/O, Analog Channels, and Counter Functions

Unit weight is approximately 660 g with dimensions of 120 mm width, 125 mm height, and 130 mm depth. The CPU 313C integrates 24 digital inputs, 16 digital outputs, 4 analog inputs, 2 analog outputs, and 1 Pt100 resistance thermometer input. Three fast counters operate at 30 kHz with frequency measurement and PID controller functions. Three pulse outputs operate at a limit frequency of 2.5 kHz. Analog inputs support 0 to 10 V, 0 to 20 mA, +/-20 mA, 4 to 20 mA, Pt100, and 0 to 600 ohm ranges with 12-bit resolution and parameterizable integration times of 2.5, 16.6, or 20 ms. Analog outputs support 0 to 10 V, +/-10 V, 0 to 20 mA, +/-20 mA, and 4 to 20 mA with 12-bit resolution and 1 ms conversion time per channel. Basic error limit at 25 deg C is +/-0.7% for voltage and current, +/-3% for resistance and resistance thermometer. The hardware real-time clock is retentive and synchronizable. Up to 3 expansion units and 31 modules per rack are supported. Programming languages include LAD, FBD, STL, SCL, GRAPH, and HiGraph. Configuration requires STEP 7 V5.1 SP2 or higher.

Field Installation Guidelines

Install the CPU in slot 2 of the S7-300 rail and secure the mounting screws. Verify 24 VDC supply polarity before energizing the backplane. Insert a micro memory card before downloading the program. Confirm STEP 7 V5.1 SP2 or higher is used for configuration. Route shielded analog and counter cables to a maximum of 100 m for technological functions; unshielded cables are permitted only for standard inputs and outputs up to 600 m. Verify total output current per group does not exceed 8 A at up to 40 deg C or 4 A at up to 60 deg C. Verify potential separation groups of 16 and 8 for digital inputs and 8 for digital outputs.
