Develop PLC program for a Test Chamber

We need a Siemens S7-1200 Program written for a small test chamber used to inject a powder into an air stream that flows through a 1 cubic meter environmental test chamber and then comes to a stop of air flow and allow the injected power to settle on small test sensors hanging in the main chamber. I would want a few safety checks and then a spin up of the fan and then after some timing, stop the fan and display the cycle on a winCC panel on the programmer laptop not on a separate panel like a 4.3" AV21232DB030AX0. We will use the laptop. There are I/O list of 4 RTDs, two RH sensors, door closed switch, door lock switch. selector switch hand auto, pressure sensor, discrete out put for fan drive, future AO for VFD of sam fan, injection solenoid for powder injection, future air flow measurment, out put for green light, red light and yellow light condition.See the attached photo of my actual build.
