Siemens S7-1500 PLC signal module

The Siemens S7-1500 PLC signal module modules are optimized for integrating more functions and supporting channel-level diagnostics. With a uniform front connector and pre-wiring, these modules can be processed either centrally directly at the CPU or distributed through the ET200MP system. The modules have different channel numbers and functions.

- Compact design with I/O templates as narrow as 25 mm.

- Integrated DIN-rail for flexible installation

- Rack expandable up to 32 templates

- Digital input module with ultra-short input delay time of 50 μs.

- Digital input modules with ultra-short input delay times of 50 μs Analog modules with 8-channel conversion times down to 125 μs

- Multi-function analog input module with automatic linearization for temperature measurement and limit value monitoring

- Back-bus communication speed increased by a factor of 40 to 400 MBaud

- Channel-level diagnostic messages for fast fault support

- Readable electronic identification code for fast identification of all components

- Unified 40-pin front connector

- Integrated shorting tabs simplify wiring

- New cover design with dual bay for maximum cable storage space

- New cover design, double bay for larger cable storage space.

- Analog modules come with cable shielding accessories

- Separate power and signal lines

- Enhance the ability of anti-electromagnetic interference

The system performance of SIMATICS 7-1500 greatly reduces the system response time, thus optimizing the control quality and improving the system performance.

Processing speed

The SIMATIC S7-1500's faster signal processing speed dramatically reduces system response time and improves productivity.

High-speed backplane bus

The new backplane bus technology utilizes high baud rates and transmission protocols for fast signal processing.

Technology integration

In the SIMATIC S7-1500, motion control functions can be integrated directly into the PLC without the need for additional modules. PLCopen technology allows the controller to connect various PROFIdrive-enabled drives using standard components. In addition, SIMATICS 7-1500 supports the TRACE function for all CPU variables, which improves debugging efficiency while optimizing drive and controller performance.

TRACE Function

The TRACE function, available on all CPUs, not only enhances the accuracy of diagnostics for user programs and motion control applications, but also greatly optimizes the performance of drives.

Motion Control Function

The Motion Control function enables the connection of various analog drives as well as PROFIdrive-enabled drives. The function also supports tacho and positioning axes.

Information integration

The SIMATIC S7-1500 offers an additional protection mechanism that covers all aspects of authorization levels, module protection and communication integrity.

The “information integration” mechanism not only secures the investment, but also continuously improves the availability of the system.

Proprietary technology protection

Encryption algorithms protect against unauthorized access and modification. This prevents the machinery and equipment from being copied, thus securing the investment.

Copy protection

The serial numbers of SIMATIC memory cards or CPUs can be bound to ensure that programs cannot be run in other devices.

This way the program cannot be copied and can only be run on the specified memory card or CPU.

Access protection

The access protection function provides a protection against unauthorized changes to the project plan. Separate access passwords for each user group are used to ensure different levels of access rights. In addition, the use of the CP 1543-1 module enhances the access protection of the integrated firewall.

Operational protection

The system protects the data transmitted to the controller from unauthorized access. The controller recognizes changed engineering configuration data or engineering configuration data from unfamiliar devices.

Design and Operation

The SIMATIC S7-1500 includes a number of new features that ensure the availability and usability of the engineering configuration to a large extent.
