7.3.4 Parameterization SIO1/2
INFO
In the IO-Link environment, the signal denotations are described from the perspective of the IO-
Link master. This means: The input on the sensor is called
DO , as DO is an output on the IO-
Link master. Conversely, DI is an input on the IO-Link master and an output on the sensor.
For SIOx mode you can select the following functions in the parameter Settings.SIOx Function
Select :
n
DI (Digital Input):
▪ State of SSC1
▪ State of SSC2
▪ Quality Bit
▪ Alarm Bit
n
DO (Digital Output):
▪ High status: Teach-in offset/tare activated
▪ Positive flank: Reset of the storage function
▪ Positive flank: Trigger of sample and hold
▪ High state: Teach-in sensitivity activated
Depending on the selected function, the SIO is connected as an input or an output.
The selected functions are also available via the cyclic PDI and PDO data. The DO or PDO
functions are internally connected
OR . This means that the internally processed signal of the in-
dividual functions is high , when either PDO, SIO1, or SIO2 is set to high .
Input delay
You can set an input delay for an input signal (DO) for each SIO ( Settings.SIOx Input Delay ). In-
put delay means that an external signal is recognized and adopted by the amplifier electronics if
the input signal is permanently in a new state throughout the time set as the input delay.
