How is the sensor powered when using the data splitter E43406?

The product is designed for retrofitting into existing applications. The IO-Link and SIO paths are electrically isolated, supply power to the sensor must come from the controller via pins 1 and 3 (SIO side).

How does the wiring of the E43406 and E43410 look like and how do analogue and digital signals reach the controller?

This is the wiring diagram of the E434xx data splitter and the EVC843 Y cable. The EVC843 guarantees correct wiring: The E434xx is connected to an IO-Link master, which is marked with (1) in the image. The other side of the E434xx connects to the EVC843 Y cable. The EVC843 has connectors, A, B and C. Connection A is labelled (4) in the image and goes to the controller. Connector B is labelled (3) and connects to the IO-Link device. Connector C is labelled (2) and connects to the E434xx splitter. From the IO-Link device pin 2 (switching/analogue output 2, if available) and pin 5 are passed straight through to the controller. On pin 4, the sensor communicates with the E434xx splitter or the connected IO-Link master via IO-Link. The data splitter reproduces the missing switching signal from output 1 and sends it to pin 4 of the controller via EVC843. Therefore, all output signals, if available, can pass through into the existing controller of the application without change in wiring or programming.

Will the data splitter work with devices that are not IO-Link capable?

No. The devices must be IO-Link capable.

IO-Link data splitter

Transmit process values to the controller and the higher IT level

In older installations, analogue or binary output signals from sensors are often sent directly to standard input cards of controllers and processed further there. Most of today’s sensors are equipped with IO-Link, meaning relevant IO-Link data would be lost with conventional use.

The IO-Link data splitter enables use and processing of this data in a conventional control system that previously operated in the standard I/O (SIO) mode. The controller-related binary signal still passes through to the PLC inputs in SIO mode. In addition, it transmits process values and other sensor data via IO-Link to higher-level systems such as moneo. Depending on the sensor, this can also be implemented for analogue signals using a Y cable. It is also possible to configure the sensor parameters using moneo and an appropriate IO-Link master.
