Decentralized Control of Valve Interfaces

IO-Link master module with Profinet S2 system redundancy controls actuators on a bioreactor

Biopharmaceuticals are the end products of highly sensitive upstream and downstream processes. Reliable operation on the controller level is essential and therefore places demanding requirements on field devices. These have to integrate in the high availability world of process automation and increasingly enable data intensive Ethernet communication. Turck's TBEN-L5-8IOL IO-Link master combines robust design, IO-Link capability and Profinet S2 system redundancy in a single device. It can establish communication relations to the primary controller as well as its backup and acts as a link between controller and IO-Link devices.

Your Benefits

  • Time and cost savings thanks to reduced cabling and easy IO-Link integration
  • IO-Link and monitoring API simplify the predictive maintenance of plants
  • Use the benefits of industrial Ethernet via Profinet in high availability systems

  • With its high protection, the I/O module can be mounted in the direct machine vicinity

  • The TBEN-L can connect eight IO-Link devices with redundant Profinet controllers

  • The TBEN-L5-8IOL is the first IP67 IO-Link master with Profinet S2 system redundancy

Time saving thanks to IP67 protection

In hazardous areas (class 1, division 2) the I/O module is mounted in the direct vicinity of fermenters. It connects IO-Link valve controllers from GEMU. Due to the short time frame available for the implementation of pharmaceutical projects, the protection classes of the multiprotocol ethernet module are a benefit. With IP67 and IP69K, mounting in a control cabinet is unnecessary, while the use of pre-assembled cables saves a lot of time.

Condition monitoring with IO-Link 

The IO-Link wiring concept makes the device installation even easier and is also an important information channel. Both data as well as supply are transferred via an unshielded cable. Besides Profinet communication, all industrial Ethernet modules from Turck also support read access to device data. SCADA, control and cloud systems can query additional device information from the field without increasing the load on the controller. This includes for example the status as well as the switch cycles of a valve or the values of a pressure sensor. This is implemented with a monitoring interface, which supports end-to-end digital communication.
