Corrected from:
No change in behaviour planned.
What happens?
When logging into the controller with the PLC Designer, the message appears:
Error during download: 2 unresolved reference(s)...
In the message window under 'Download', reference is made to the unresolved references for the blocks 'L_SSYP_STOREPERSISTENTMOTIONDATA' and 'L_SSYP_RESTOREPERSITENTMOTIONDATA'.
When does the behaviour occur?
The behaviour occurs when the function block L_Util_Retain is used in a project for a c520 or c550 controller. However, the function block is only intended for the Lenze controller 3200C.
Which products are affected?
Cabinet Controller c520
Cabinet Controller c550
Short-term measures:
Remove all instances of the function block L_Util_Retain from your project.
Evaluation / recommendations:
The power-failure-proof data (RETAIN) are automatically stored on the SD card. This means that they can still be used when replacing the unit. The function block L_Util_Retain is not supported by the Lenze controllers c520 and c550.
