Siemens IO-Link –
completely integrated in Totally Integrated Automation (TIA)


IO-Link in substations and IO-Link on the field level enable communication through sensors and actuators on the last steps to the process.
Only the seamless integration in the automation concept Totally Integrated Automation (TIA) shows the full potential of the communication standard in substations as well as on the field level.

It enables simple, consistent, and open engineering. Comfortable parameterization and diagnosis are made possible through freely available modules of SIMATIC. Pre-integrating Siemens devices into SIMATIC HMI eases commissioning and operation.

The deployment of smart Siemens devices and IO-Link on the field level raises quantity and quality of usable information and thereby enables fast intervention in case of incidents.

In addition to this, it makes the integration into the energy management easier and speeds up the commissioning of actuators, sensors, and switchgear.
Plant availability is improved by preventive maintenance. Diagnosis down to the field level in the entire plant as well as fast troubleshooting reduces downtime. 


Reduced engineering times

  • Standardized, open system for greater flexibility (IO-Link devices from third party suppliers can be integrated in the engineering)

  • Standardized, transparent configuration and programming by means of integrated engineering (SIMATIC STEP 7)

  • Freely available function blocks for SIMATIC for convenient parameterization and diagnostics, as well as for reading out measured values

  • Efficient engineering due to pre-integration of Siemens devices into SIMATIC HMI

  • Low error rate during CAD circuit diagram design due to reduction of control current wiring

Shorter commissioning times

  • Faster installation with minimized failure rate due to reduction of the control currentwiring

  • Less space needed in the control cabinet

  • Economical wiring technology with several load feeders due to unrestricted use of existing Siemens components

Increased plant availability

  • High level of transparency in the plant right down to the field level

  • Shorter standstill and maintenance downtimes due to plant-wide diagnostics and faster troubleshooting

  • Support of predictive maintenance

  • High degree of transparency due to integration in energy management systems, readout of current values and diagnostic messages.

  • Shorter changeover times due to central management of parameters and recipes, even for field devices
