New and original PLC 6ES7331-7KF02-0AB0 analog input SM331 Ximen potential isolation PLC module

Overview of Siemens S7-300

Modular micro PLC system to meet the performance requirements of small and medium-scale;

Various performance modules can meet and adapt to automation control tasks very well;

Simple and practical distributed structure and multi-interface network capability, the application is very flexible;

Easy operation, simple design, no fan;

can be expanded smoothly when tasks increase;

A large number of integrated functions make it very powerful.

S7-300F overview:

Fail-safe automation system, which can meet the increasing safety requirements of factories;

based on S7-300;

Additional ET 200S and ET 200M distributed I/O stations equipped with safety modules can be connected;

Carry out safety-related communication through PROFIBUS DP which adopts PROFIsafe profile;

Standard modules can also be used for non-safety-related applications.

Siemens S7-300 function

provides a large number of functions to support users' S7-300 programming, debugging and maintenance work.

High-speed command processing:

The instruction execution time starts from 4 ns, opening up a new application in the low-end performance range.

Floating point operations:

Floating point arithmetic and even complex number arithmetic functions can be used efficiently.

User-friendly parameter assignment:

Only a software tool with a unified operation interface is needed to complete the parameterization of all modules. This reduces entry barriers and training costs.

Operator Control and Monitoring (HMI):

The user-friendly HMI service has been integrated in the S7-300 operating system. These functions no longer require costly programming work: the SIMATIC HMI system requests process data from the SIMATIC S7-300, and the S7-300 operating system completes the automatic transmission of these data at the expected update time. And it uses exactly the same symbols and databases.

Diagnostic function:

The CPU's intelligent diagnosis system continuously detects system functions, records error information and specific system events (for example, time errors, module failures, etc.). These events have been time-stamped and stored in a circular buffer for future troubleshooting.

password protection:

Use the password protection function to be efficient to prevent unauthorized copying and modification.
