Product: Electronic pressure switch with display, model PSD-4
1. Description of the IO-Link functionality
IO-Link is a point-to-point connection for the communication of the PSD-4 with an IO-Link master.
2. Physical layer
The PSD-4 supports the following features:
IO-Link specification: Version 1.1
SIO mode: Yes
Minimum cycle time: 2,3 ms
Rate: COM2 (38.4 kBaud)
Process data length: 16 bit (Frametype 2.2)
Support of data storage: Yes
Smart Sensor Profile: Yes
3. Process Data
The PSD-4 has 1 or 2 digital outputs and is optionally available with an 4 …20 mA or 0 …10 V
analogue output signal. Both physical switching outputs are also transmitted as process data via
IO-Link.
In the 'SIO Mode' (Standard I/O Mode, without IO-Link operation) the switching output 1 will switch
on pin 4 of the M12 connector. In the IO-Link communication mode, this pin 4 is reserved
exclusively for communication.
With a Frametype 2.2, the 16-bit process data from the pressure switch is transmitted cyclically.
Bit 0 is the state of switching output 1 and Bit 1 is the state of switching output 2, where 1
respectively DC 24 V correspond to the "closed" logic state of the respective output.
The remaining 14 Bit contain the analogue value measured by the pressure switch. According to
the measuring range of the sensor and the unit configured, the 14 Bit process data of the
measured value, is dynamically adjusted. Multiplying the process data with the gradient (Index #
67) allows for a pressure reading in the selected unit.
Example:
Measuring range of the sensor = 0 ... 10 psi
ProcessData range = 0...1,000 with Gradient = 0.01
In this example: ProcessData = 500 = 5.0 psi
Changing the unit, will result in new ProcessData range and Gradient.

4. Service data (ISDU –Indexed Service Data Unit)
Service data is always acyclic and exchanged on the request of the IO-Link Master.
With the help of the service data, the following parameter values or instrument status can be read:
