I would like to hire a PLC & SCADA Programmer

6 output temperature control program using Siemens Logic 8 PLC.

I need the control system to keep a maximum setpoint temperature. Measured from temperature thermistor.

The heat load is from 6 seperate relays. If the temperature exceeds setpoint eg. (25deg celcius) i need the first relay to be opened for a adjustable period ie. (2 hours). If this then fails to keep temperature i will need the next relay to be opened as well.

I need the relay that needs to be opened to change every 2 hours to the next relay. until the temperature lowers below setpoint.

If the setpoint is then reached again the next relay needs to open.

This needs to occur in a rotation so that over time all relays share the opening evenly
