Transmission of result table to the PLC system

Hello,
Is it possible to transmission of result table to the PLC system (for
example via RS232)?
If is used Clarity for control and acquisition of process chromatograf
(continuous cyclic analyse), we would send information to the PLC (value of
concentrations for 4 peaks) after each analysis.

Furthermore I'm interested in possibility SST to alarm by overrun of
torelable concentrations.
Is the Clarity able to switch TTL-outputs at overrun set point for each
peak?
Best Regards

Yes,

after the analysis is finished, in the Settings, PostRun, the Export data option can be selected (select the Result in the Settings, Data Export window) and a Run Program with the %e (=exported file name) parameter command performed. You can write such a program to send the exported file over the serial line to PLC.

The SST Events actions allows only to pause a sequence or to run a program based on the SST result (OK, unknown, fail).

To activate TTL or relay outputs, you can use the method Event table with the Input> event type to react to the signal higher then preset value. Please note, that logical sum (i.e. connecting the digital outputs in a serie) will allow to limit this action to a specific time window by activating the second output at appropriate times.
