  2. CPU Specifications CPU 314 IFM Hardware overview

  3. CPUs and Hardware/Software versions

  4. The CPU 314IFM is available in 2 versions: • with slot for memory card (6ES7314-5EA10-0AB0) • without slot for memory card (6ES7314-5EA0x-0AB0/6314ES7314-5EA8x-0AB0)

  5. SIMATIC Documentation on the Internet • http://www.ad.siemens.de/support

  6. Control and Display Elements

  7. Control and Display Elements of the CPUs

  8. Differences Between CPUs

  9. Status and Fault Displays

  10. Mode Selector Switch

  11. Backup battery/accumulator • Exceptions • The CPUs 312IFM and 313 do not have a real time clock so they do not need an accumulator battery. • The CPU 312IFM does not have a buffer which means that you can not insert a battery. • Backup battery or rechargeable battery? • Next table shows the differences in the backup provided by an accumulator and a backup battery.

  12. Memory card • Purpose of the Memory Card • With the memory card, you can expand the load memory of your CPU. • You can store the user program and the parameters that set the responses of the CPU and modules on the memory card. • You can also back up your CPU operating system to a Memory Card. exceptCPU 318-2. • If you store the user program on the memory card, it will remain in the CPU when the power is off even without a backup battery.

  13. Available Memory Cards

  14. MPI and PROFIBUS-DP Interface

  15. MPI interface • The MPI is the interface of the CPU for the programming device/OP and for communication in an MPI subnet. • Typical (default) transmission speed is 187.5 Kbps (CPU 318-2: adjustable up to 12 Mbps). • Communication with an S7-200 requires 19.2 Kbps. • The CPU automatically broadcasts its set bus parameters (e.g. baud rate) at the MPI interface. This means that a programming device, for example, can automatically ”hook up” to an MPI subnet.

  16. PROFIBUS-DP Interface • CPUs equipped with 2 interfaces provide a PROFIBUS-DP interface connection. • Transmission rates up to 12 Mbps are possible. • The CPU automatically broadcasts its set bus parameters (e.g. baud rate) at the PROFIBUS-DP interface. This means that a programming device, for example, can automatically ”hook up” to a PROFIBUS subnet. • In Step 7 you can switch off automatic transfer of bus parameter.

  17. Removing and Inserting Modules in the MPI Subnet • You must not plug in or remove any modules (SM, FM, CP) of an S7-300 configuration while data is being transmitted over the MPI. • If you remove or plug in S7-300 modules (SM, FM, CP) during data transmission via the MPI, the data might be corrupted by disturbing pulses. • You must not plug in or remove modules (SM, FM, CP) of an S7-300 configuration during data transmission via the MPI!

  18. Clock and Runtime Meter

  19. Testing Functions • The CPUs offer you the following testing functions • Monitor Variables • Modify Variables • Forcing (note the differences between CPUs) • Monitor block • Set Breakpoint

  20. S7 314 IFM Technical Specifications

  21. Special Features • Integrated I/Os (wired with 40-pole front connector)

  22. Memory card • The CPU 314 IFM is available in 2 versions: with and without Memory Card slot. • With slot for memory card: 6ES7 314-5AE10-0AB0 • Without slot for memory card: 6ES7 314-5AE0x-0AB0
