Overview of PLC Siemens S7-1500

1. Overview

+ The most modern PLC of Siemens up to the time plctop .com wrote this article

+ Compact, modular, scalable model, all protected under IP20.

+ System solution for many automation applications.

+ Highest performance in the whole Siemens plc system.

+ Configuration only in TIA with STEP 7 Professional V12 or later.

2. Performance of Siemens S7-1200

Increase performance through:

+ Faster order execution
+ Language expansion
+ New data types
+ The bus port transmits data faster.
+ Optimal code generation

3. Strong Communication

+ PROFINET IO (2 port switch) as standard communication;
+ From the CPU 1515-2 PN, one or more PROFINET interfaces are additionally integrated, e.g. for network separation, connection of additional PROFINET devices or for high-speed communication as an I-Device
+ OPC UA Data Access Server as a runtime option for easy connection to SIMATIC S7-1500 in third party devices/systems.
+ Expandable with communication modules for bus systems and point-to-point connections.

4. Integrated Technology of Siemens S7-1500

+ Motion control integrated without additional modules:

+ Normalization blocks (PLCopen) for analog connection and PROFIdrive

+ The motion control function supports speed control, positioning axis, relative synchronous operation (synchronization without synchronous position specification), as well as external encoders, cams and heads. probe.

+ Extensive motion control functions such as absolute synchronous operation (synchronizing with synchronous position specification) and camera are also integrated in the technology CPU.

+Comprehensive detection for all CPU tags for real-time diagnostics and sporadic fault detection for efficient operation and rapid optimization of steering and control equipment.

+ Maximum control functions.

+ Safe Integration:

Failsafe SIMATIC S7-1500(T) Failsafe controller to process programs according to safety standards.

+ Integrated Security:

Protect data by creating a password against arbitrary reading and modification of program blocks.
Copy protection against unauthorized copying of program blocks
Permission concept with four different authorization levels
Different access rights can be assigned to different user groups. Level 4 protection makes it possible to limit communication with HMI devices.
Improved operation protection
Protection to use Ethernet CP (CP 1543-1)
Additional access protection with firewall
Establish a secure VPN connection.

5. Design of Siemens S7-1500

+ Controller:

Connectors are integrated on the sides. As a result, the modules can be easily inserted into the CPU, both saving space, saving installation time and bringing beauty to the system.
The s7_1500 CPUs and modules are mounted on their own rails of varying lengths. A variety of standard components such as additional terminals, small circuit breakers or small relays can be damaged if the DIN rail is not suitable.
Trusted and friendly line
The I/O signals are connected by the 40-pin front connector. The mechanical encoding between the signal module and the front connector helps to prevent damage to the device due to accidental insertion.
The wire connection for the front connector is simple, easy to change the position.
Front connectors are available in versions with screw terminals or push connectors. Both versions allow connection of wires with cross-sections from 0.25 mm2 to 1.5 mm2 (AWG 24 to AWG 16).
Additionally, wiring via TOP Connect is also available for digital signal modules. It allows for quick and clear connection to sensors and magnetic actuators as well as simple wiring in the control cabinet.
For analog modules, the screen can be mounted directly on the module; A shield connector can be installed for this module to connect to the CPU.
Set up the conversion and expansion station
Signal modules and communication modules can be inserted in any way without restriction. The system will configure itself.
The maximum configuration includes a CPU with 31 modules (30 modules + 1 power supply).
Compact size.
Flexible settings.

+ I/O Modules:

Standard and fail-safe digital input modules
Standard and fail-safe digital output modules
Digital input/output module
Analog input module
Analogue input/output module
Analog output module
Includes high-speed analog (HS) modules with a base execution time of 62.5 μs, regardless of the number of trigger channels
Technology modules for counting and positioning
Communication module for point-to-point and bus connections
