Order number: 6ES7312-1AE13-0AB0 Siemens CPU312 CPU 312 is installed: a microprocessor; processor instruction time per binary up 100 ns. Extended memory; 32 KB RAM associated with the implementation of high-speed block (equivalent to approximately 10 K instructions) can provide sufficient space for the user program; SIMATIC Micro Memory Card (up to 4 MB) as load memory program, but also allows the project (including symbols and comments) are stored in the CPU. Flexible expansion capabilities; up to 8 modules (1 row structure) MPI multi-point interface; integrated MPI interface can establish up to six connection with S7-300 / 400 or programming device, PC, OP while. In these connections, always for the programmer and OP were reserved for a connection. By "global data communication", MPI can be used to create up to 16 CPU consisting of a simple network. 6ES7312-1AE13-0AB0 CPU312,32K memory 6ES7 312-5BE03-0AB0 CPU312C, 32K memory 10DI / 6DO 6ES7 313-5BF03-0AB0 CPU313C, 64K memory 24DI / 16DO / 4AI / 2AO 6ES7 313-6BF03-0AB0 CPU313C-2PTP, 64K Memory 16DI / 16DO 6ES7 313-6CF03-0AB0 CPU313C-2DP, 64K memory 16DI / 16DO 6ES7 314-1AG14-0AB0 CPU314,96K memory 6ES7 314-6BG03-0AB0 CPU314C-2PTP 96K memory 24DI / 16DO / 4AI / 2AO 6ES7 314- 6CG03-0AB0 CPU314C-2DP 96K memory 24DI / 16DO / 4AI / 2AO 6ES7 315-2AG10-0AB0 CPU315-2DP, 256K RAM 6ES7 315-2EH14-0AB0 CPU315-2 PN / DP, 384K RAM 6ES7 317-2AJ10-0AB0 CPU317- 2DP, 512K RAM 6ES7 317-2EK13-0AB0 CPU317-2 PN / DP, 1MB RAM 6ES7 318-3EL00-0AB0 CPU319-3 PN / DP, 1.4M memory password protection; the user program is password protected to prevent unauthorized access. Diagnostic buffer; diagnostic buffer stores the last 500 errors and interrupt events, including the 100 events can be long-term retention. Maintenance-free data backup; if a power failure occurs, the CPU can keep all the data is automatically written to the SIMATIC Micro Memory Card (MMC card), and will be again when the power is unchanged. The feature can be parameterized using the configuration attributes and CPU response STEP 7, S7, parameter setting: MPI multi-point interface; Define the station address restart / cycle time characteristics; maximum cycle time and load limits, as well as self-test function clock memory; set the address of protection; access system diagnostics program and data definition; scope definition process and diagnostic alarms watchdog interrupt; clock interrupt cycle setting; set the start date, start time and the interval period show function and functional status and fault indication information; light-emitting diode display, for example, hardware, programming, timer, or I / O errors and operating modes such as RUN, STOP, Startup. Test function; the programmer can use to display the signal status during program execution, and can not be modified by the user program process variables, and output the contents of the stack. Information function; you can use PG plain text access to storage capacity and CPU operation mode, information about the current utilization of the main memory and load memory and the current cycle times and diagnostic buffer contents.
