Distributed process I/O: maximum availability and flexibility
Distributed process I/O for SIMATIC PCS neo and SIMATIC PCS 7: the right solution for every requirement
Today, the acquisition and output of process signals via sensors and actuators can take place in a variety of ways: centrally or locally, via 4...20mA / HART, PROFIBUS or PROFINET. SIMATIC PCS 7 and SIMATIC PCS neo offer a correspondingly wide range of options for safely processing the large number of different I/O process signals: Either with the modular SIMATIC ET 200 I/O or the compact SIMATIC CFU.

The future-proof I/O solution for every requirement in the process industry
The SIMATIC PCS 7 and PCS neo process control systems use the various benefits of distributed process I/O from Siemens. These enable maximum availability for 24/7 operation 365 days a year through redundant configurations or use in explosive gas/dust atmospheres.
As individual as your requirements
Flexible, decentralized solutions have become the state of the art in automation for the process industry. Whether compact or modular, installed in the control cabinet or directly in harsh industrial environments, for the connection of 4..20MA / HART signals or PROFIBUS PA - the SIMATIC hardware for the process industry offers the right solution for rugged and future-proof connection of sensors and actuators for every application.
Promote digitalization and protect investments!
Process control technology from Siemens paves the way for plant-wide digitalization. By supporting Ethernet-based PROFINET standard, our innovative hardware not only bridges the digital communication gap into the field level – but also from today into the future. The distributed SIMATIC I/O systems offer high planning reliability for up to 30 years or more. Standards are the prerequisite for compatibility and promote broad acceptance in various areas of the process industry.
- Fully compatible successor products enable easy replacement
- Fast and simple functional expansion is permanently guaranteed
- Seamless reuse of existing modules and cabling
SIMATIC PCS 7 and SIMATIC PCS neo offer a correspondingly wide range of options for reliably processing the large number of different process signals: Either with the modular SIMATIC ET 200 I/O or the compact SIMATIC CFU.
The SIMATIC ET 200SP HA covers the highest requirements for availability and ruggedness and is designed for all applications, such as functional safety or explosion protection. With up to 32 channels on a width of 22.5mm, it is also a real space-saving wonder. If distributed process I/O are required for installation directly in hazardous areas, the SIMATIC ET 200iSP is used. The SIMATIC CFU sets new standards for simple device integration and consistent decentralization.
Powerful solutions that can be adapted to any automation task
The SIMATIC ET 200 product family has always been a guarantee for powerful, rugged and future-proof solutions that can be individually adapted to any automation requirement. The I/O system is ready for use inside and outside the control cabinet and can be configured as required: Modules for digital and analog inputs/outputs, optionally with HART, safety technology, frequency inverters and other technology modules ensure that you can equip your I/O system with the appropriate signal and function modules.

The right solution for every requirement
The powerful, compact I/O system with Safety Integrated
SIMATIC ET 200SP HA
The compact modular SIMATIC ET 200SP HA I/O creates space in the control cabinet and makes it possible to align the expansion in the control cabinet exactly with actual requirements. And the tool-free connection technology with push-in terminals and vertical wiring reduces engineering, assembly and cabling costs. Thanks to its extended temperature range from -40°C to +70°C and conformal coating, the I/O system is ideally suited for use in the field.
Thanks to the newly available Ex-I/Os, SIMATIC ET 200SP HA offers the ideal solution for the special requirements of the Ex field. The new Ex-I/O modules can be installed at levels up to ATEX Zone 2, and provide intrinsically safe Ex-ia circuits for field devices up to Zone 0. Fail-safe digital I/O modules and a fail-safe analog input module are available for applications in the area of functional safety.
The cost-effective solution for the Ex field
SIMATIC ET 200iSP
The intrinsically safe, modular SIMATIC ET 200iSP distributed I/O system is the cost-effective solution for areas at risk of explosion. It is particularly flexible in its engineering, assembly and wiring, with minimal overheads. Intrinsically safe I/O may be directly installed in potentially explosive gas and dust atmospheres, i.e. in Zones 1 and 2 as well as 21 and 22; sensors and actuators can be located directly in Zones 0 and 20. Extensive standards and approvals are available for the SIMATIC ET 200iSP.
The smart field distributor
Benefit from greater flexibility and easier handling coupled with maximum availability: The compact field distributor is installed at the process level and is connected via PROFINET directly to the process control system to form the foundation for digitalization in the field.
The SIMATIC CFU combines a digital fieldbus with conventional I/Os and is suitable for use directly in the field, as far as Ex Zone 2. This significantly reduces the footprint of the entire I/O system: Conventional control cabinets are a thing of the past and significant savings can be made with regard to cables and terminals, as well as in the planning and documentation work. The device reduces the potential for errors during operation, simplifies plant expansions or modernization, and reduces the amount of work required for the hardware FAT.
SIMATIC CFU PA Edition: Plug-and-produce simplicity
The PA edition of the SIMATIC CFU combines the ruggedness and simplified handling of the PROFIBUS PA communication standard with all the advantages of the PROFINET standard based on Industrial Ethernet. This compact hardware innovation automatically initializes connected field devices and integrates them into the process control system. What used to take 30 minutes is now done in less than one minute. That’s plug-and-produce!
SIMATIC CFU DIQ Edition: Easy and flexible use of discrete I/Os
With sixteen freely configurable, digital I/O channels and optional extension functions, the SIMATIC CFU DIQ Edition offers you even more flexibility and easier handling coupled with maximum availability. The additional operating modes “Counter” and “Frequency measurement” can be activated for selected digital inputs. In addition, the safety function “Actuator disconnection” can be set for the digital outputs. This function enables you to bring your actuators to a safe position as required to avoid possible hazardous situations.
Fast and robust fieldbus communication
Distributed I/O devices such as remote I/O stations with their I/O modules, transmitters, drives, valves or operator terminals communicate with the automation systems at field level through a powerful real-time bus system. The universal PROFIBUS covers all of the requirements of the process industry and has already proven itself as a rugged and reliable communication medium at the field level.
Field instrumentation is connected using PROFIBUS PA, which enables power to be supplied via the fieldbus in addition to communication. This standard can be seamlessly integrated into the SIMATIC PCS 7 and PCS neo process control systems as a link via PROFINET or alternatively via PROFIBUS DP.
Talk to your Siemens contact if you have any questions about integrating Foundation Fieldbus in PCS 7.
To create a smooth network transition between PROFIBUS DP and PROFIBUS PA, the SIMATIC product range offers two versions: the DP/PA coupler and the PA link. The DP/PA coupler is especially suitable for low quantity structures (data volumes) and low timing requirements. The DP/PA link is ideal for a large number of stations and high cycle time requirements.
Compact Field Unit PA (CFU PA) offers the ideal solution for network transitions between PROFINET and PROFIBUS PA.
With conventional fieldbus installations, changes during runtime are only possible to a very limited extent. This is because short-circuits or contact bounces when connecting or replacing devices can lead to the failure of the fieldbus segment. Fieldbus installations with active field distributors from SIMATIC permit the addition and removal of field devices and of active field distributors during operation without any disruption.
