Hi,
Environment:
– Prosys SDK: 4.0.2-808
– Prosys OPC UA Simulation Server (v3.2.0-214)
+ The simulation server is configured with several data nodes (for each numeric data type one variable).
+ Checkbox “Run Simulation” is switched off.

– data to write to the OPC UA server: UnsignedByte value = UnsignedByte.valueOf(28);

Test 1.
– For each data nodes on the server run “writeValue(…, value, false).
– Result:
+ Only the data node with type “UNSIGNED BYTE” succeeded. For the others I got a StatusException: Bad_TypeMismatch.
+ The value on the OPC UA server has changed.
=> Test OK.

Test 2.
– For each data nodes on the server run “writeValue(…, value, true).
– Result:
+ For each data node “writeValue(…, …, true) succeeded.
+ But non of the data nodes on the OPC UA server has changed. (The data node with the correct type hasn’t changed too !)
=> Test FAIL.
I would expect the value 28 could be changed into every other numeric type and written to the data nodes.

The behavior is reproducible with other OPC UA servers too.
