Summary0007559: IncrementUaVariantArray exception if value < -incValue
Description

When running Monitor Items Deadband Filter/014.js, the server had a byte array containing a value where one of the bytes was 3. This caused the test case to throw an exception and fail.

When IncrementUaVariantArray runs on the array, line 258 of UaVariantToSimpleType.js tests if (3 >= (255 - incValue)). incValue is -11, and 3 is < 266, so it then adds incValue to the byte. 3 + incValue = -8. byteArrayToByteString then throws an exception since it is not expecting negative values.

To resolve this, the upper limit of Constants.Byte_Max for increasing has been extended by a lower limit of 0 to take negative increasing into account.
