Commissioning
In Direct Write mode, the modified variable is transferred directly. If the IO-Link device
supports this, it is always transferred with block parameterization in order to ensure data
consistency and to back up its value in the data storage.
Note
Note difference between "Block Write Mode" and "Direct Write Mode"
Do not confuse "Block Write Mode" and "Direct Write Mode" with the use of block param-
eterization
10.2.3.4.5.4 Upload and Download
The upload and download function always uses block parameterization if the IO-Link de-
vice supports it.
The read/write variables that are visible in the respective user role are transferred. If the
device is to be backed up so it can be replaced, or so a new application can be initialized
with the saved data, the "Specialist" role is required for this.
When the connection to the WAGO IO-Link master is established or the device control is
activated, the data is not automatically synchronized with the device. This was a deliber-
ate choice, since there are IO-Link devices with a great number of variables and low per-
formance for transferring them. Therefore, it is possible to load individual variables by
clicking on the device's Status column with the mouse and only transferring modified vari-
ables in "Block Write Mode."
