A field of reactions is transferred to the function. The function seeks out the first reaction and outputs a corresponding string. If no reaction is found, the function outputs the string 'None'.
| Output | Data type | Description | 
|---|---|---|
| q_etDiag | General, library-independent statement on the diagnostic. A value unequal GD.ET_Diag.Ok equates an error message. | |
| q_etDiagExt | POU-specific output on the diagnostic. q_etDiag = GD.ET_Diag.Ok -> status message q_etDiag <> GD.ET_Diag.Ok -> diagnostic message | 
| Input/Output | Data type | Description | 
|---|---|---|
| iq_stReaction | Field of the reactions |
