Description of the IO-Link functionality (optional)
IO-Link is a point-to-point connection enabling communication between PSD-30 and an
IO-Link master.
Physical layer
The PSD-30 supports the following features:
IO-Link specification
SIO Modus
Min. cycle time
Rate
Process data bandwidth
Process data
The PSD-30 has 1 or 2 digital outputs. Both switching outputs are transmitting process data
via IO-Link.
In the so-called SIO mode (default I/O mode), i.e. no IO-Link operation, the switching output 1
is switched at pin 4 of the M12 connector.
In the IO-Link communication mode this pin is reserved exclusively for the communication.
The switching output 2 at pin2 of the M12 connector is always switched additionally.
For the frametype 2.2 the16-bit process data of the pressure switch are transmitted cyclically.
Bit 0 inidcates the status of the switching output 1 and bit 1 the status of the switching output
2.1 corresponds in this case to the logical state "closed" or + DC 24 V at the corresponding
output.
The other 14 bits contain the analogue measured value of the pressure switch.
The upper limit of the measuring range (MBA) matches the value 1000 d and the lower limit of
the measuring range (MBE) has the value 9000 d.
