S7+ driver RID / LID to plain text address

Hello all,

I've been getting strange log messages of the S7+ driver recently:

WCCOAs7plus (1), 2025.06.27 12:14:08.275, PARAM,SEVERE, 51/s7plus, GetVariablesCallbackHandler, error_get, _ae_touPlc addr: Rid:2316173333Lid:2550.9.12.21.8.1.10, Value out of range detected (-9129204363372593213)

WCCOAs7plus (1), 2025.06.27 12:14:09.629, PARAM,SEVERE, 54, Unexpected state, NotificationHandler, handle_notification, _ae_touPlc addr: Rid:2316173333Lid:2550.9.12.21.4.1.9, Invalid value retrieved for subscription. Access denied = 1, Out of memory = 0, Status = 10

Does anyone know how to convert those IDs (e.g. Rid:2316173333Lid:2550.9.12.21.4.1.9) to plain text address or DPE so I can start trying to figure out what is causing the problem?

A DPE ID normally consists of 2 numbers if no system name is given, the DP ID and the element ID. These parts of the DPE ID are separated by a dot ".". If you get an identifier with a different format it is not a DPE identifier.
In the described issue it looks some id information defined in the PLC.

When looking at the description of S7+ error codes in the WinCC OA Documentation you will find the information that these error codes are coming from the IOMS library (3rd party software used for the S7+ driver).
