Selected IO-Link port mode. Valid settings are:
•
Reset - Select to disable a port or to reset/restart an IO-Link port.
•
IO-Link - Select to connect and operate an IO-Link device on the port.
•
Digital In - Select if a DI device is attached to the port.
•
Digital Out - Select if a DO device is attached to the port.
If enabled and the Port Mode is Digital In or Digital Out, this option inverts the I/O
value.
•
False (Disabled - Do not invert IO)
•
True (Enabled - Invert IO)
Note: This option does not affect the Auxiliary Input.
If the port mode is Digital Out, defines the default digital output value that is used at
startup and when there is no active PDO controller.
•
Off (low voltage) - 0
•
On (high voltage) - 24V
The minimum, or fastest, cycle time at which the IO-Link device may operate. The
valid range is 4-538 ms.
You can leave the Minimum Cycle Time set to the default value and the IO-Link
Master negotiates with the IO-Link device for its minimum cycle time. The IO-Link
Diagnostics page displays the Actual Cycle Time, which is the negotiated cycle
time.
Indicates that the data storage for the port is empty or displays the Vendor ID and
Product ID of the data stored on that port.
When this option is initially set to On, the IO-Link Master saves the data storage (if
the data storage is empty) from the IO-Link device to that port. Some IO-Link
devices update the data storage contents if you use the Teach buttons on the IO-
Link device, but that is determined by the IO-Link device manufacturer.
Automatic upload occurs when the Automatic Upload Enable option is set to On
and one of these conditions exists:
•
There is no upload data stored on the gateway.
•
The IO-Link device executes a requests_ at upload function (generally because
you have changed the configuration via Teach buttons).
Do not enable both Automatic Upload and Automatic Download at the same time,
the results are not reliable among IO-Link device manufacturers.
When a port contains data storage for an IO-Link device and if you attach a device
whose Vendor and Device ID do not match, the IO-Link LED on the IO-Link Master
flashes red to indicate a wrong device is attached. In addition, the IO-Link
Diagnostics page displays DV: Wrong Sensor in the IOLink State field.
You should not enable Automatic Upload until after you have configured the IO-
Link device attached to the port unless you want to capture the default settings.
Refer to Data Storage for more information.
