Corrected from:
3200C controller V3.13
Response of the new version:
As of version V3.13, the persistent axis data is retained after device replacement when using the L_Util_Retain block.
What happens?
After replacing a 3221C or 3231C controller, the persistent axis data (e.g. homing information) is reset to its default values although the L_Util_Retain block has been used.
When does this behaviour occur?
If the L_Util_Retain block is used in a project, the block saves the retain data on the SD card when the project is started or on request by the user. In this way, a 3221C or a 3231C controller can be replaced with a replacement device and the remanent data can be transferred to the replacement device by taking over the SD card from the original device into the replacement device.
If the original device is equipped with firmware version V3.12 or lower, the persistent axis data is reset to its default values after device replacement.
Which products are affected?
3221C and 3231C controller from V3.9
Short-term measures:
None
Evaluation/recommendations:
If a 3221C or a 3231C controller with firmware version V3.12 or lower is replaced, the persistent axis data is reset. Therefore, e.g. homing must be repeated for the axis.
