Electronic module 4SI SIRIUS


Besides the IO-Link master SIMATIC ET200S 4SI, the electronic module 4SI SIRIUS facilitates the cost-optimized connection of IO-Link-capable SIRIUS switching and monitoring devices to the distributed I/O system ET 200S. It thus supports the integration of SIRIUS industrial controls in the established field bus systems PROFIBUS and PROFINET and consequentially in Totally Integrated Automation.

The distributed I/O ET200S supports accommodation of up to 64 IO-Link electronic modules 4SI SIRIUS.

Cost-optimized connection of up to 16 IO-Link-capable SIRIUS devices per electronic module 4SI SIRIUS via 4 ports is supported.

Application areas

  • Connection of exclusively IO-Link-certified SIRIUS devices in all automation application areas

Product-specific IO-Link advantages

  • Seamless integration of IO-Link-certified SIRIUS devices in TIA

  • Uniform engineering, from the master to the device – all data in one S7 project

  • PtP communication with IO-Link-certified SIRIUS devices by Siemens

  • Transparent, central device diagnostics

  • Degree of protection IP20

  • Transparent device parameter representation

  • Dynamic parameter changes directly via the control

  • Easy function representation in STEP 7 via freely available function blocks

  • Firmware upgradeability directly via the field bus


  • Single-slot (15mm) electronic module ET 200S

  • Max. line length to the IO-Link device: 20m

  • 4 IO-Link ports for exclusive coupling of SIRIUS devices

  • Support of firmware updates

  • Support of I&M data

  • Support of transmission rates: COM1 and COM2

  • Operating modes per channel: IO-Link or disabled; adjustable via S7-PCT

Configuration of the IO-Link ports is realized via the S7-PCT port configuration tool, which is integrated in STEP7 Engineering and is also available as "stand-alone" tool.
