Which datatype does the dp element have you are writing using the C# manager?
Do you get the same error when the value is set with the UI, e.g. the PARA module?

Which WinCC OA version are you using?

Hi

1- the datatypes are various : bool, integer.....
2- No, we don't have this kind of exceptions when seting values from Para

Possibly you can do the following test to get more detailed information:
-- Start the project
-- Wait until the startup is finished
-- Set a dp element (config + attribute) using your API manager
-- Check if the log message occurs
-- Set the same dp element (config + attribute) using the PARA module
-- Check if the log message occurs

If the message was written when the value was written by the API manager
-- Activate the debug flag "-rcv 2" for the Data Manager
-- Set the same dp element (config + attribute) using your API manager
-- Check if the log message occurs
-- Set the same dp element (config + attribute) using the PARA module
-- Check if the log message occurs
-- Deactivate the debug flag "-rcv 0" for the Data Manager

In the log file for the Data Manager WCCILdata0.log you can see which messages have been received by the Data Manager.
Probably you can find a difference in the messages send by the API and the UI manager.
