          PRODUCT DESCRIPTION

          6ES7312-5BE03-0AB0 CPU 312C Compact Controller

          Siemens 6ES7312-5BE03-0AB0 is the CPU 312C compact controller for SIMATIC S7-300. It combines 32 kB of nonexpandable work memory with ten integrated digital inputs and six digital outputs. Load memory is provided through a SIMATIC Micro Memory Card, with a supported maximum of 4 MB. The CPU has no integrated analog channels.

          The integrated RS485 interface provides MPI communication at up to 187.5 kbit/s; an onboard PROFIBUS DP interface is not provided. The CPU supports 128 S7 counters, 128 S7 timers and 128 bytes of bit memory. Integrated functions include two frequency-counter channels up to 10 kHz and two PWM pulse-output channels up to 2.5 kHz. The documented supply is 24 V DC within a 20.4 to 28.8 V permissible range.

          SYSTEM INTEGRATION

          Integrate 6ES7312-5BE03-0AB0 within SIMATIC S7-300

          Configure the CPU 312C in the S7-300 rack with the appropriate Micro Memory Card and the engineering support applicable to its hardware and firmware. The 32 kB work memory cannot be expanded by fitting a larger card; the card provides load memory, with a documented maximum of 4 MB.
          Assign the ten integrated digital inputs and six outputs according to the CPU 312C terminal diagram. The default input addresses extend from 124.0 to 125.1 and the default output addresses from 124.0 to 124.5. Select frequency-counter or PWM functions deliberately where those terminals are used for high-speed tasks.
          Connect MPI using the prescribed RS485 arrangement and a rate not exceeding 187.5 kbit/s. Do not configure the integrated port as PROFIBUS DP. Check the project memory allocation, retentive areas and startup state before enabling the connected outputs.

          Features:

          • Supply voltage: 24 V DC; permissible 20.4 to 28.8 V
          • Typical no-load current: 60 mA
          • SIMATIC S7-300
          Use 6ES7312-5BE03-0AB0 only within the documented SIMATIC S7-300 arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 6ES7312-5BE03-0AB0 within SIMATIC S7-300

          Record the 6ES7312-5BE03-0AB0 order code, CPU hardware and firmware, MMC content and integrated I/O assignments. Keep the CPU 312C identity separate from CPU 312 IFM or later CPU 312C order codes, which can have different memory and project requirements.
          Back up the application and establish the approved safe output state before isolating the rack. Preserve the Micro Memory Card and note the MPI address and baud rate. Inspect the removable connector and any counter or PWM wiring before installing replacement hardware.
          Restore the supported project and confirm that the hardware configuration recognizes the replacement CPU. Verify integrated I/O, counter or pulse functions, MPI access and retained data. Review the diagnostics buffer and startup behavior before returning the process to service.
