Shanghai Automation Technology Co., Ltd. Li Hui (Siemens sales agent) Contact: Xu, Li Hong (sales engineer) 24-hour sales technical service hotline: 15021672309 Telephone (Tel) :021-33737848 fax (Fax) :021-33737848 E-mail (Email): 780099838 @ qq.com Business (QQ): 780099838 QQ:? program memory and data structures 780099838 Overview with medium and large capacity, if needed, can be used for SIMATIC configuration tool and the use of binary floating-point arithmetic has higher processing power? ? use with centralized and distributed I / O on the production line as a centralized controller? PROFIBUS DP master / slave interface? for a large number of I / O expansion? used to build a distributed I / O structure? In synchronous mode operation requires CPU SIMATIC Micro Memory Card (MMC) Area of ??application CPU 315-2 DP is a medium-sized program memory and with PROFIBUS DP master / slave CPU time on the PROFIBUS interface realization. In addition to the centralized I / O structure, which can be used for distributed automation structure. It is often used as a standard PROFIBUS DP master station in the SIMATIC S7-300. The CPU is also used as a distributed intelligent devices (DP slaves). It has been optimized in accordance with the quantification framework for the use of SIMATIC engineering tools, such as:?? With SCL programming with S7-GRAPH sequential control programming Additionally, CPU is using software to implement some simple craft task provides an ideal platform For example:? simple motion control using STEP 7 blocks or run the software, "standard / Modular PID Control" closed-loop control tasks to achieve a solution through the use of SIMATIC S7-PDIAG process diagnostics can expand?. Design CPU 315-2 DP is installed: a microprocessor; processor for each binary instruction processing time is about 50 ns, each floating-point operation as 0.45 μs?. ? 256 KB work memory (equivalent to about 85 K instructions); segment associated with the execution capacity of the working memory may provide sufficient space for the user program. As a program is loaded micro memory card (up to 8 MB) may also allow projects (including symbols and comments) stored in the CPU. The load memory can also be used for data archiving and recipe management. ? Flexible expansion capabilities; Up to 32 modules (4-row structure) MPI multi-point interface;? Integrated MPI interface can simultaneously establish a connection with S7-300/400 or 16 programming device, PC, OP's. In these connections, is always reserved for the programmer and OP were 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 / build high speed from the CPU 315-2 DP interface can be used, 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). Fully supports PROFIBUS DP V1 standard. It improves the DP V1 standard from diagnosis and parameterization capability stations. ? Functions password protection; user program is password protected to prevent unauthorized access. ? Diagnostics buffer; diagnostic buffer can store the last 500 errors and interrupt events, of which 100 events can be long-term retention. ? Maintenance-free data backup; If power is interrupted, CPU all the data (maximum 128 KB) automatically written SIMATIC Micro Memory Card (MMC card), so that the data can be used again after the voltage is restored, and the change will not occur. The feature can be parameterized using the configuration, attributes, and the CPU in STEP 7 S7's response parameter settings: MPI multi-point interface; define the station address restart / cycle time characteristics; maximum cycle time and load restrictions, and self?? ? detection clock memory; setting address protection class;? defined programs and data access system diagnostics;?? process and define the scope of diagnostic alarms watchdog interrupt; period set the clock interrupt;? set the start date, ? start time and the interval period PROFIBUS DP master / slave interface; user-defined distributed I / O addresses and information display functional status and fault indication;? LED indication hardware, programming, time, I / O, the battery and the bus Errors and operating status (eg RUN (run), STOP (stop) and start). ? 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; You can use the programmer in the form of plain text storage capacity and access to CPU operation mode, the current utilization, and information about the current cycle time and the diagnostic buffer content of the work and load memory. ?????? Integrated communication functions PG / OP communication Global data communication S7 basic communication S7 communication (only server) routing data routing system function block has a wide range of system CPU features, such as: diagnostics, parameter assignment, alarm, timer and measurement.
