Execution conditions
The following shows the conditions for automatic uploading and downloading of IO-Link device parameters.
Conditions
IO-Link device
parameters on non-
volatile memory
Not exist
Exist
*1 Even if the device validation result is match, the parameters may not be automatically downloaded properly if the structure of IO-Link
device parameters has been changed. When the firmware version of the IO-Link device is defined, the firmware version is checked
during automatic downloading, and a notification is issued as an event if the firmware version is different. (Parameters are automatically
downloaded even if the firmware versions are different.)
*2 If IO-Link device parameters are the same, they are not downloaded automatically and no processing is performed.
■When IO-Link device parameters on non-volatile memory do not exist
In the following cases, IO-Link device parameters do not exist on the non-volatile memory.
• When no IO-Link device parameters have been uploaded so far since the shipment from the factory
• When no IO-Link device parameters have been uploaded so far since when the operation mode was set to other than IO-
Link mode and the IO-Link device parameters on the non-volatile memory were cleared
■During processing of IO-Link device connections
This means the timing at which connections established with IO-Link devices operating in IO-Link mode are detected by the
IO-Link module.
■During processing of IO-Link device parameter changes
This means the case where IO-Link device parameters are changed by a device mounted on the IO-Link device.
