Function

The faster SIMATIC S7-1500 controller provides higher functionality, with bit instruction processing times as low as 1ns and floating-point instruction processing times as low as 10ns (depending on the CPU type, this is not possible in the first release of products). The speed of the backplane bus is 40 times that of the S7-400PLC; Because code generation is optimized, the response speed of the CPU is compared to that of existing controllers.

Each CPU is equipped with a PROFINET IO (2-port switch) standard interface. CPU 1516-3PN/DP also has an integrated PROFINET basic interface, for example, it can be used for network blocking.

In addition to integrated interfaces, each SIMATIC S7-1500 controller can also be expanded through communication modules or communication processors. This provides many other connection methods, such as connecting through PROFIBUS, connecting through Ethernet, or connecting through serial interfaces using dedicated protocols such as USS or Modbus RTU.

Integration skills

The SIMATIC S7-1500 can integrate motion control functions into the PLC without the use of any additional modules. After PLCopen, this controller provides standardized blocks that can be used to connect analog drivers and PROFIdrive drivers. The motion control function supports the speed axis, positioning axis, and external encoder.

In order to effectively debug and quickly optimize the driver and closed-loop controller, SIMATIC S7-1500 also provides a wide range of tracking functions for all CPU variables, which can be used for real-time diagnosis and non punctual fault detection.

In addition to the driver function, the S7-1500 also provides rich closed-loop control functions, such as actively optimizing control parameters through easily configurable blocks to achieve good control quality.

In addition, technical modules can also be used to perform functions such as high-speed counting and azimuth capture, or to perform measurements on signals ranging from 24V to 200kHz.

Integrated security functions

When used in conjunction with STEP7, each CPU will provide common sense maintenance based on the code, which can avoid unauthorized reading and changing the content of the program block.

Copying maintenance enhances security protection and prevents unauthorized copying of program blocks. The detailed program block can be linked to the serial number of the storage card, so that the program block can only be executed after the configured storage card is inserted into the CPU.

Moreover, the controller has four different levels of security access to assign different access permissions to different user groups.

Due to improved operation and maintenance, the controller can detect data changes or unauthorized configuration data transmission.

The Ethernet communication processor (CP 1543-1) provides additional visit maintenance for users through a firewall and can establish a secure VPN connection (V12SP1 and higher versions).

Planning and Operations

All SIMATIC S7-1500 CPUs come with a display screen. Through this display screen, users can read information such as the order number, firmware version, and serial number of any connected module; Additionally, without the need for programming devices, the IP address of the CPU and other network settings can be adjusted locally.

Fault messages are displayed on the screen in general text format, which helps to shorten downtime.

All modules use consistent front connectors, and integrated voltage jumpers can form sensitive voltage groups, simplifying inventory.

Because the S7-1500 device rail integrates standard device rails, it is convenient to install additional components such as active fuses and relays.

In the assembly equipment, the SIMATIC S7-1500 controller can be expanded through signal modules. So, through space saving expansion, one can be sensitive and accustomed to each application. When this controller was introduced to the market, there were already various analog and digital modules available.

The system cable kit used for digital signal modules can quickly and clearly connect on-site sensors and actuators (completely modular connection, including front connector module, connector wire and connector module, as well as simple wiring inside the switchgear (sensitive connection, including front connector with pre assembled single core).

In addition, a power module for supplying 24V voltage to the module and a system power supply for internal module circuits were also provided for the S7-1500.

Through the IM 155-5 PROFINET interface module used in the ET 200MP I/O system, up to 30 signal, communication, and technology modules can be utilized. So, the components and system strengths of S7-1500 are also applicable to distributed equipment. Regardless of whether the module is running in a centralized equipment next to the S7-1500 controller or in a distributed equipment completed through ET 200MP, users do not see any differences in operation and system functionality. The high-power backplane bus selected in both systems can shorten the bus cycle time and response time, even for large station equipment and high quantity construction.

Integrated system diagnostic function

The diagnostic function of the integrated system has been pre activated for the CPU of the S7-1500 series; The system diagnosis information is consistently displayed in general text form on display screens, TIAPortal, HMI, and web servers, and can even display audio messages from frequency converters; Nowadays, this type of diagnosis will also be provided during periods of CPU downtime. If equipped with new hardware components, proactively update the diagnostic information.

SIMATIC STEP 7 Professional V12 Engineering Configuration Software

The new SIMATIC S7-1500 controller series can only be configured using STEP 7 Professional V12 and higher in the Totally Integrated Automation Portal. SIMATIC STEP 7 Professional V12 is an engineering configuration system used for intuitive processing of SIMATIC S7-1500. In addition to configuring the S7-1500, it can also configure the S7-300/400 and S7-1200 controllers.

Compatibility

The integrated porting in SIMATIC STEP 7 Professional V 12 provides the following support:

Switch from S7-300/S7-400 to S7-1500 controller and actively change program code. Some program codes that cannot be actively changed will be recorded and can be manually modified. The STEP7V11 project can be used in a compatible form for STEP7 V12. Moreover, the S7-1200 program can be converted to S7-1500 through posting/copying functions.
