In these firmware archives only the last two legacy firmware versions are included.
If you are looking for older firmware versions, please contact your local sales representative.
u-create web is the basis of all web-based PLCs (UC20-W stands for web) from Weidmüller.
Depending on, what software-modules you want to use, you can decide which product(s) you have to order.
If you need further information, simply take a look at engineering and visualisation tools.
The only difference is, that with the IoT variant, you don't have the 'Programming'-module for IEC61131-3 programming available. You can still access the global variables via Node-RED, or use other modules of u-create-web, besides the programming module, for example ModBus TCP or OPC-UA.
Modules can be bought or installed for free. For further information, simply take a look at Engineering and Visualisation Tools
When updating to a newer firmware version:
The real-time project will automatically be migrated and can be used without changes.
Notice: Please also check for version changes of Node-RED in the release notes and the details in the Node-RED's forum .
When downgrading to a previous firmware version:
If you downgrade the device to a previous firmware version your project might become incompatible or lost.
Notice: It is always advisable to save project data before upgrading to a newer firmware version.
You just perform the ‘Firmware update’ operation and select the next available firmware version. Latest firmware is available in the download area.
Note: For dedicated firmware versions (e.g. 1.9.X and 1.12.X) there are additional update steps required. Please read always the 'Release Notes' document and execute the upgrade instructions which are applied for the target firmware version.
Please always execute the downgrade instructions described in the 'Release Notes' document. The release notes and downgrade support images are available in the Archived firmware section of the product download area.
Note: After execution of the downgrade procedure all project data are lost and configuration data are set to factory default values. That includes also IP addresses and means that the device can be accessed via default IP address after downgrade operation.
