Area of ??application CPU 314C-2 DP is a compact CPU, can be used in systems with distributed architecture. Through its extended working memory, the compact CPU also applies to medium-sized applications. PROFIBUS DP master / slave interface supports the connection of distributed I / O's; directly connected to the integrated digital and analog I / O, and process support. Therefore, CPU 314C-2 DP can be used both for rapid pretreatment distributed unit can also be used as a bit taken off the fieldbus system host controller. Other uses integrated technology projects include: Counting frequency pulse width modulation measurement cycles PID control positioning control Design CPU 314C-2 DP installed:??????? Microprocessors; processor time available for each binary instruction up to 60 ns. ? Extended memory;-speed 192 KB working memory (equivalent to approximately 64 K instructions) for the block is executed, can provide enough storage space for SIMATIC Micro Memory Card (up to 8 MB) for the user program as a load memory program also allows The project (including symbols and comments) are stored in the CPU. ? Flexible expansion capabilities; Up to 31 modules (4-row structure) MPI multi-point interface built-MPI interface can build up to 12 simultaneously with S7-300/400 or PG, PC, OP connection?. In these connections, always were PG and OP each retain a connection. By "global data communication", MPI can be used to create up to 16 CPU consists of a simple network. ? PROFIBUS DP interfaces: with PROFIBUS DP master / slave interface for CPU 314C-2 DP can be used to build high-speed, easy to use distributed automation systems. For users, distributed I / O unit can be used as a centralized unit to handle (the same configuration, addressing, and programming) built-in input / output;.? In CPU 314C-2 DP, and provides 24 digital inputs (all inputs can be used as alarm handling), 16 digital outputs and 4 analog inputs and 2 analog outputs (for current / voltage signals), as well as an additional input path (for measuring temperature ( Pt100)), so that it can become the host control system. ? Functions password protection; user program is password protected to prevent unauthorized access. ? Block encryption; Functions (FC) and function blocks (FB) by S7-Block Privacy, encrypted and stored in the CPU in order to protect our proprietary technology. ? Diagnostics buffer; diagnostic buffer can store the last 500 errors and interrupt events, including the 100 events can be long-term storage. ? Maintenance-free data backup; If power failure occurs, the CPU can by all data (maximum 64 KB) is automatically written to the SIMATIC Micro Memory Card, and will be again when the power remains unchanged. The feature can be parameterized using a response configuration, attributes, and the S7 CPU with STEP 7 for parameters settings: SUMMARY: Define name, the name of the host system name and location of the MPI multi-point interface; define the station address to start; define CPU???

Test function; programmer can be used to display signal status during program execution, and can not be modified by the user program process variables, and the output stack contents. ? Messaging; programmer in text form by providing storage capacity information for the user, the operating mode of the CPU and main memory and load memory current usage, contents of the current cycle time and diagnostic buffer. ???? Integrated communication functions PG / OP communication Global data communication S7 basic communication S7 communication (only server) record routing routing data integration capabilities counter;??? Four counters (up to 60kHz), with independent direction comparator can be connected directly to the 24V incremental encoder. ? 4 channel frequency measurement; allowing frequency measurements (up to 60 kHz), for example, (the number of pieces of each measurement cycle) measured shaft speed or throughput. ? Cycle measuring four channels. Measurable count signal cycle time, counting frequency up to 1 KHz. ? Pulse width modulation; 4 output can be directly connected to the control valve, the actuator, the switching device, heating devices, such as sampling frequency of 2.5 kHz. You can set and change the duty cycle length at runtime. ? Positioning control is integrated in the operating system SFB by two digital outputs or an analogue output on an axis positioning control. ? Alarm inputs (all digital inputs); alarm input can detect the sequence of events, and triggers a response in the shortest possible time.
