Port Status Modules

There are two Port Status modules:
 IO-Link Status Module
 Digital I/O Module.
3.7.2.1 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 IO-Link Status module.
Each IO-Link port is mapped into one bit of each byte in the IO-Link Status module as shown in this
table. 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 as active when it is configured correctly and has a working IO-Link device

IO-Link Master I/O settings
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.
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.
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)
