How I can send setpoint=0 to one out of 3 mass flow controller after 5s of first setpoint

[Abot]

Dear All,

I'm using a FlowDDE to controlling 3 Bronkhost Mass Flow Controllers (MFC), and Keithey 2700 datalogger driver for monitoring 10 channels of thermocouple.

Is that possible to send setpoint=0 to one of the MFCs to zero if after 5 seconds sending the first setpoint the temperature reading is below 50 oC? If yes, can anybody tell me how I should do this.

Best regards,

Abot

sorry,i mean to send setpoint=0 automatically after 5 seconds if i.e. T1 less than 5 oC
