The SIMATIC ET 200S is a distributed I/O system to degree of protection IP20. It comprises:

• Interface module with PROFIBUS or PROFINET interface, alternatively with integrated CPU
• Input/output modules
• Technology modules
• Frequency converters and motor starters for three-phase loads

Its extensive module spectrum and system-wide handling of configuring, installing and programming tasks make the ET 200S well-suited as a universal I/O system.

The discretely modular design ensures fast and optimum adaptation to system requirements:

• No need to keep spares
• No superfluous channels

Even when requirements change frequently, replacement or combining of different I/O modules can noticeably reduce setting-up times.

With a data signaling rate of up to 12 Mbit/s on the PROFIBUS DP and extremely powerful internal data transport capabilities, the ET 200S is also eminently suitable for extremely time-critical applications.

Two different variants are available for integrating safety technology with ET 200S.

• With conventional wiring, SIGUARD components achieve Safety Category 4 according to EN 954-1 with motor starter applications
• PROFIsafe components replace the wiring-based safety logic with a freely-programmable controller. This has the following advantages for the customer:
• Programming in the familiar STEP 7 programming environment in the LAD and FBD languages;
• no separate tool is required for programming or configuration
• The safety program executes in the same controller as the standard program;
• a separate controller is not required
• Safety-related data can be transferred over the same fieldbus cable as standard data;
• no additional wiring of the safety-related inputs and outputs is necessary
• Safety-related inputs and outputs can be combined with standard inputs and outputs within a DP station; no additional safety-related DP nodes (stations) are necessary

The design of the ET 200S allows it to be used in areas subject to increased mechanical stress.

The system characteristics meet high plant availability requirements.

The following components are available for the ET 200S distributed I/O system:

Interface module IM 151

for connecting the PROFIBUS DP (IM 151-1, IM 151-7) or PROFINET (IM 151-3, IM 151-8) to the ET 200S Station. The terminating module is included in the scope of delivery of the interface modules.

Mounting

The ET 200S is designed with permanent wiring. In the process, the terminal module is snapped onto a DIN rail (35 x 15 x 7.5 mm) and can be pre-wired and tested without an I/O module. In addition, this design supports the removal and insertion of I/O modules during energization for the replacement of modules in RUN mode and for rapid error locating with regard to the affected module without having to turn off the power (hot swapping).

The automatic coding of the I/O modules reliably prevents the risk of injury to persons and/or destruction of modules through accidental mounting of the wrong module.

Only a few rules have to be observed when configuring an ET 200S station:

Expansion limits

The configuration limits for an ET 200S station vary in accordance with the interface module used. The following parameters can limit the configuration scope:

• Number of I/O modules that can be plugged in; 12 or 63 I/O modules can be plugged in depending on the interface module
• The maximum permissible width of an ET 200S station is 1 m or 2 m depending on the interface module.
• The maximum address space for all I/O modules plugged in is 88 byte, 100 byte, 128 byte or 244 byte (for input and output data) depending on the interface module. This limit is not applicable to the CPU versions
• The maximum number of parameters is restricted to 244 byte per station. This limit is not applicable to the CPU versions With STEP 7 V5.3 SP3 and higher, stations with more than 244 byte of parameters can also be configured using the IM 151-1 High Feature and Standard (6ES7 151-1AA05-0AB0 and higher)

Configuring rules

• The first I/O module of an ET 200S station must always be a power module (with the exception of ET 200S COMPACT)
• The thermal continuous current, per voltage group, for the load or encoder supply can be up to 10 A
• With the exception of the following modules, all the electronic modules must be operated in a load group supplied with 24 V DC: The electronic modules within a load group may be combined as desired
  • 2 DI 120 V AC: Operation in 120 V AC load group
  • 2 DI 230 V AC: Operation in 230 V AC load group
  • 2 DO 120/230 V AC: Operation in 120 V AC or 230 V AC load group, depending on the load
  • 4 DI 24 to 8 V UC: Operation in load group with the required supply voltage: 24 to 48 V AC or DC

Terminal modules

Various terminal modules are available for a very wide range of requirements. The TM-P, TM-C and TM-E are also available with screw-type or spring-loaded terminals. All TM-P and TM-E of 15 mm width can be supplied alternatively with the no-strip fast connection terminals "FastConnect".

Depending on the selected combination of I/O and terminal module, differing terminal assignments result.

A universal terminal module TM-E15x26-A1 is available for universal applications with electronic modules. This supports all the connection types including 3-wire connection for 4-channel digital modules with electronic modules of 15 mm width. The precise pinouts for the different combinations are listed in the manual.

Mode of operation

Via PROFIBUS DP or PROFINET a central controller can access the I/O modules of the ET 200S in the same way as central I/O modules.

Communication is handled entirely by the master interface (in the central controller) and in the IM 151. Interference-free internal data transport is using shielded leads.

Comprehensive, channel-specific and easy-to-program diagnostics with clear text messages allow for the localization and correction of plant errors in the shortest time and significantly increases availability.

Configuration, parameterization and diagnostics

The configuration and parameterization of the ET 200S is achieved using STEP 7 or the configuration tool of the PROFIBUS master or PROFINET controller used.

During plant configuration it should be assured that the selected PROFIBUS DP-master has sufficient resources available for the DP network.

The ET 200S and its I/O modules provide the user with complete and channel-specific diagnostic information. For example, integrated, electronic short-circuit protection for the sensor power supply of digital HF input modules reduces troubleshooting to a minimum, thus increasing the availability of the plant. A diagnostic package with function blocks for SIMATIC S7-CPU and images for various OPs is provided at no charge for the simple evaluation of diagnostic information.
