SIO Digital Input and Output Module Parameters
SIO Digital Input
Invert IO (Default: False)
If enabled, this inverts the I/O value.
False (Disabled - Do not invert IO)
True (Enabled - Invert IO)
Note: This does not affect the Auxiliary Input.
Input Settling Time (0 - 10000ms)
Default
= 0ms
If non-zero and Mode is set to Digital-Input, the required time
that the input status must remain constant before an input
status change is reported.
Input Hold Time (0 - 10000ms)
(Default: 0ms)
This is how long the IOLM keeps the input at its present value.
For example, if the IOLM detects the input to go too high, and
the hold time is X milliseconds, then the IOLM reports the
input as high for X milliseconds, even though the input itself
may have gone away already. If X is zero, then you get the
behavior currently in the field.
SIO Digital Output
Invert IO (Default: False)
If enabled, this inverts the I/O value.
False
(Disabled - Do not invert IO)
True
(Enabled - Invert IO)
Note: This does not affect the Auxiliary Input.
Default Digital Output (Default: Off)
Defines the default digital output value that is used at startup
and when there is no active PDO controller.
Off
(low voltage)
On
(high voltage)

IO-Link Status Module
IO-Link Status Module
IO-Link Status module is a 4-byte input-only module that provides status information of all IO-Link
ports. The following table shows the data format of the IO-Link Status module.
Byte Offset
Status Byte Description
0
IO-Link Active
1
IO-Link PDI Valid
2
IO-Link Auxiliary Input
3
IO-Link Error
Each IO-Link port is mapped into one bit of each byte in the IO-Link Status module as shown in this
table.

Port 4
Port 3 Port 3 Port 1
For IO-Link Active status byte (offset 0), a bit one means the corresponding IO-Link port is active. An IO-
Link port is considered active when it is configured correctly and has a working IO-Link device
attached.
A bit one in IO-Link PDI Valid status byte (offset 1) means the PDI data from the corresponding IO-Link
port is valid. PDI Valid is only applicable to IO-Link port modules that have input data.
