Corrected from:
Controller c300 V3.20
Controller 3200C V3.20
Panel Controller p300 V3.20
Panel Controller p500 V3.20
Response of the new version:
With the current version of the Lenze controllers, variables of type STRUCT or ARRAY OF STRUCT can be accessed via OPC/UA in read or write mode without errors.
If a variable of the application in the controller is accessed via OPC/UA, this leads to an error message, e.g.:
BadNotReadable
When does this behaviour occur?
Access (read/write) to variables of type STRUCT or ARRAY OF STRUCT via OPC/UA leads to an error message if the individual elements of the structure are not accessed.
Which products are affected?
Controller c300 from V3.13
Controller 3200C from V3.13
Panel Controller p300 from V3.13
Panel Controller p500 from V3.13
Short-term measures:
Access only the single elements of a multi-element variable (e.g. STRUCT or ARRAY OF STRUCT) via OPC/UA.
Evaluation/recommendation:
It is not possible to access multi-element variables of the application in the controller via OPC/UA. However, it is possible to access their individual elements.
