We want sent the result(component concentration) to the PLC(DCS) through analog output(4-20ma) after every cycle.
Have any option parts(software or hardware)could achieve this function
THANKS

DataApex is not manufacturing any hardware with such output (4-20 mA). However, it is probably possible to use some commercially available serial-to-analog converter ( e.g.
http://www.laurels.com/transmitter-serial2analog.htm), which will use results exported from Clarity for sending into converter.
In Clarity is is possible to set automatic export of results after finish of each analysis (Instrument - Setting - Postrun - Export Data), then it is necessary to extract the particular result and save it as a new file, which will be sent into converter. Extracting can be performed using some Excel macro, for example.
