Scalability, performance and usability

The signal modules or I/O modules provide the interface between the controller and the process. The controller detects the current process status by means of the connected sensors and triggers the corresponding actuator reactions.

The digital and analog modules provide exactly the inputs/outputs that are required for the respective task. They can be used both centrally, i.e. directly on the CPU, as well as locally in the ET 200MP I/O system. 25 mm and 35 mm modules are available.

The analog modules possess expanded functions like oversampling, measuring range adjustments or scaling of measured values.

Scalability allows customized and cost-effective implementation of the application

Modules available with different numbers of channels and functionalities
Increased function density for compact design and reduced number of variants
U-connector with self-assembling backplane bus
Space-saving installation of additional components possible on mounting rail

Maximum system performance for fast processes and very high control quality

PROFINET IRT for isochronous mode with clock rates up to 250 μs
Digital input modules with very short input delay of 50 μs
Analog modules with conversion time of 62,5µs rsp. 125 µs for 8 channels
Universally usable analog input module with independent characteristic linearization for temperature measurements and threshold monitoring (two high and two low limits); very simple stocking of spare parts, as all measurement types and measuring ranges are combined in one module

Increased functionality, more efficient diagnostics through the systematic use of PROFINET

Channel-selective diagnostic alarms support faster troubleshooting and thus minimize plant downtimes
Channel-selective diagnostic LEDs on the module and one-to-one mapping to the channel indicate to the service technician the precise path to the location of the fault. They thus insure fast detection and correction.
Electronic rating plate that is readable for clear identification of all modules; fast and clear identification of the module in a service scenario, for example

Easy evaluation of channel diagnostics, independent of diagnostic interrupts, through the use of the value status (QI; Quality Information)
Integration of simple counting functionality with the High Feature digital input modules allows cost-effective implementation of simple counting tasks (DI16x24VDC HF; DI 32x24VDC HF)

Cost savings in the control cabinet through intelligent product design

All modules can be used centrally (S7-1500) and distributed in the
ET 200MP I/O system
Uniform 40-pin front connector for all modules either with screw type or, optionally, push-in terminals
Same signals always on the same pin, i.e. schematic macros created once can be used again at any time, wiring errors are
avoided
Fast and simple connection of sensors and actuators to the efficient SIMATIC TOP connect system cabling

Integrated potential bridges simplify wiring
Scalable cable stowage compartment creates space for wires with thick insulation
Pre-latch position allows prewiring without electrical connection
Mechanical slot coding prevents mistakes when plugging and swapping modules
Imprinted wiring scheme allows wiring without additional documentation
Direct creation of the labeling strips from the TIA Portal; no additional tools are required; double entry of absolute addresses and tag names is avoided

Robust design ensures trouble-free plant operation

Shielding is already integrated; all required components are included and do not have to be ordered separately. System is installed without tools and requires no additional installation space
The modules of the ET 200MP / S7-1500 IO are also available as SIPLUS version with extended ambient conditions, e.g. extended temperature range of -40 °C to +70 °C

Investment protection

Continuous firmware update keeps modules permanently up to date and ensures that investment is always well protected. New functions can be optionally retrofitted in existing hardware
S5/S7-1500 I/O adapters allow an easy transition from S5 systems to the S7-1500. The field wiring can remain. Gradual commissioning and shadow or parallel operation of S5 and S7-1500 are possible.

Safety Integrated

The failsafe S7-1500 /ET 200MP I/O modules allow the processing of safety related as well as standard programs. Their functional safety is certified in accordance with IEC 61508 (2nd Edition). They are designed for safety-related use up to SIL 3 according to IEC 62061 and PL e according to ISO 13849.

Digital Input Modules SM 521

The modules have high channel density and low parts variance. As a result, ordering, logistics and spare-parts inventory are considerably simplified.

High Feature modules with enhanced functionality are only available with the 35mm form factor. Modules with a width a width of 35 mm can be equipped with a front connector using screw terminal or push-in technology, the connector has to be ordered separately.
The narrow 25mm modules use a front connector with push-in technology which is included in the scope of delivery. The modules have the same mechanical structure as the 35 mm modules. They also offer the same operability and the same accessories. Moreover, the pin assignment in the wiring is unchanged. This means that circuit and wiring diagrams can be universally used.

The narrow, low-cost modules do not have any parameter assignment or diagnostics, so integration in the engineering is significantly easier.
The narrow 25 mm modules can be mixed with the 35 mm modules as required.
