Siemens CPU315-2DP detail
With large capacity, the program memory and data structure, if necessary, can be used for the SIMATIC configuration tool
Has the high processing ability of binary and floating point arithmetic
In a centralized and distributed I/O production line as the centralized controller using
PROFIBUS DP master / slave interface
For a large number of I/O expansion
Used to build distributed I/O structure
In the PROFIBUS to achieve synchronous mode etc.
CPU need to run the SIMATIC micro memory card (MMC)
Siemens CPU315-2DP description
CPU 315-2 DP is a large and medium-sized program memory and PROFIBUS DP master / slave interface CPU. In addition to the centralized I/O structure, it can also be
For distributed automation structure.
It is in the SIMATIC S7-300 is often used as a standard PROFIBUS DP master. The CPU is also used as a distributed intelligent devices (DP from the station).
It has been in accordance with the quantitative framework for optimization, in order to use the SIMATIC engineering tools, such as:
The use of SCL programming
Sequence control programming with S7-GRAPH
In addition, CPU uses software to realize some simple process task provides an ideal platform, for example:
Simple motion control
Use STEP 7 to block or running software "standard solutions / modular PID control" to achieve closed-loop control task
By using the SIMATIC S7-PDIAG can realize the expansion process diagnosis.
Siemens CPU315-2DP overview
CPU 315-2 DP is installed:
The microprocessor;
The processing time for each binary instruction processor is about 50 ns, each time for 0.45 floating-point budget s.
256 KB working memory (equivalent to approximately 85 K instruction);
With high working memory capacity related to the implementation of the program segment can provide sufficient space for the user program. Miniature memory as program memory card (maximum loading
8 MB) will also permit can project (including symbols and notes) stored in CPU. Load memory can also be used for data archiving and recipe management.
Flexible and extensible;
As many as 32 modules, (4 row structure)
MPI multi point interface;
The integrated MPI interface can set up with S7-300/400 or programmable devices, PC, OP 16 connection. In these connections, always is the programming
Device and OP are reserved for a connection. Through the "global data communication", MPI can be used to create a simple network consisting of up to 16 CPU.
PROFIBUS DP interface:
With the PROFIBUS DP master / slave interface CPU 315-2 DP can be used to build distributed automation system of high speed, easy to use. For users, the distributed
The I/O unit can be used as a centralized unit to deal with (the same configuration, addressing and programming).
Full support for PROFIBUS DP V1 standard. It improves the DP V1 standard from the ability of diagnosis and parameter station.
The SIEMENS CPU315-2DP features
Password protection;
The user program using password protection, prevent illegal access.
The diagnostic buffer;
Can store the last 500 errors and interrupt event diagnosis buffer, 100 events can be long-term retention.
Maintenance free data backup;
If power is lost, CPU will all data (maximum 128 KB) automatically written to the SIMATIC micro memory card (MMC card), so that the data can be in power
Pressure recovery again after use, and will not change.
The characteristics of parametric
You can use the STEP on the S7 7 configuration, properties and the response to CPU parameter setting:
MPI multi point interface;
Define the station address
Restart / cycle time characteristics;
The maximum cycle time and load limit, and self detection function
Clock memory;
Set address
Protection grade;
Definition of program and data access
System diagnosis;
Treatment and diagnosis of alarm scope definition
The watchdog interrupt;
Periodic set
The clock interrupt;
Set the start date, start time and the interval period
PROFIBUS DP master / slave interface;
User defined distributed I/O address
Display function and information function
State and fault indication;
LED indicates the hardware, programming, time, I/O, a battery and a bus error and the operation of state (such as RUN (run), STOP (stop) and start).
Test function;
You can use the programmer display signal state during execution of a program, can modify the process variables are not by the user program, as well as the output stack contents.
Information function;
The current use of you can use the programmer YISHION text form to obtain the CPU storage capacity and operating mode, working memory and memory as well as the current cycle loading rate
Related information content of the ring buffer time and diagnosis.
Integrated communication function
PG/OP communication
The global data communication
S7 basic communication
S7 communication (only server)
Routing
The block of data routing
The function of the system
CPU has the characteristics of wide system function, such as: diagnosis, parameter assignment, alarm, timing and measurement etc..
