I am working with the Siemens Logo8! PLC (0BA8 version) and the purpose of my circuit seems to be simple:
If temp > 25°C then output voltage = 8V
If temp < 25°C and >15°C then output voltage = 5V
If temp <15°C then output voltage = 2V
Is there a possible way in a circuit of doing this?
I achieved a similar concept by using one Analog Input, then 2 Analog Threshold Triggers connected to a latching relay and eventually to a Digital Output. (Picture attached) However, the limitations of that system is that Voltage can be either 1 or 0.
The concept behind the circuit seems to be simple but I am really struggling to make it work and any hints will be much appreciated.
