IO-Link Port modules are allowed in Slots 1 to 8 on the IOLM. Slot 1 is corresponding to IO-Link Port 1.
Slot 2 is for IO-Link Port 2, so on and so forth. If a slot is unpopulated, the corresponding IO-Link port is
not configured. That port uses the previously configured settings, or default settings if it has not been
configured before.
IO-Link Port Settings (IO-Link Port Module Parameters)
Additional IO-Link port settings can be configured by using module parameters.
IO-Link Port Module Parameters
IO-Link Port Config
Minimum Cycle Time
(Default: 4)
Valid range: 4-538ms
The minimum or fastest cycle time at which the IO-Link device may
operate.
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.
Data Storage Config
Automatic Data Storage
Upload Enable
Default
: Off
When this option is initially set to
On
, the IOLM 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 request_ at the 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 IOLM 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 10.2. Data Storage on Page 136 for more
information.
