Hi, As from TIA V18 it is possible to integrate PRODIAG features for Graph blocks in WinCC Unified. Online documentation Available in: Help, Show Help, Information System, Visualizing process (RT Unified), Using the diagnostics functions (RT Unified), Process diagnostics (RT Unified) Concept: ProDiag is an efficient and easy way to use messages specially developed for operation supervision of machines / plants. A special characteristic is the possibility to show online, in the HMI/PC RT, the user program block (e.g. Graph) that generates the message. It makes it easier for the operator to find and correct by itself (without help of maintenance people / configuration software) operations problems (like “a forgotten open door”). Principle: “In STEP 7, you create operand supervisions and configure the settings according to your requirements. When an error occurs, a supervision alarm is generated based on the criteria you have configured.” An alarm will appear if the supervised signal AND the condition (one or more, sometimes optional) are present during at least a configured (optional) time. An alarm will go out immediately if the supervised signal OR condition will not present. Types: ProDiag permits to classify the message in different levels / types. Types are a fixed messages classification in ProDiag. All types have the same configuration properties (despite some attributes being mandatory for some types and not for others). This division is mainly as classification proposes (I.e. there is no technical reasons to the user use them with other intends...):
Configuration: PLC side
On PC runtime side
TIPs: To open TIA Portal, the check box “Allow start of external processes via Unified Runtime” (Runtime Manager, Security tab) should be set. Alternatively, the PLC Code Viewer control could also be address from a selected alarm message by the system function OpenPlcCodeViewFromAlarm.

Hi As from TIA V19 (V18 + up), there are two new objects: Criteria analysis control and Prodiag overview. Sample project (archived from TIA Portal as .zap19 and after that compacted in .zip format to be uploaded here) user= User, all password = Password1!
