output
0 No output signal at C/Q channel
1 Output signal at C/Q channel
DVSx Input value valid (Data Valid Signal)
0 The IO-Link data are invalid.
Possible causes:
n Sensor supply is below the admissible range.
n IO-Link port is parameterized as simple digital input.
n no device connected to the master
n no input data received from the connected device (only
valid for devices with an input data length > 0).
n No reaction from the connected device to the sending of
output data (only valid for devices with an output data
length > 0).
n The connected device sends an error "process input data
invalid”.
1 The IO-Link data are valid.
IO-Link process input
data
Process input data of the connected device The order of the IO-Link
process input data can be changed via the parameter "Process input
data mapping".
