Hi chaps
I am trying to program a Mitsubishi alpha 2 with function blocks. I have a biomass boiler with 4 pumps in a heating distribution system. I need to control the speed of 2 of the pumps according to the temperature of the buffer tank. Ie if the tank temp is 70degC then run the pump at 100%, then as the tank tank temp drops so does the speed of the pump.
Could anyone help me with this please?
PS I have a type K thermocouple as the input, and I'm using an analogue expansion slot on the plc! Plc model is AL2-14MR-D and expansion slot is AL2-2DA
The output is to an ABB acs150 VFD
Regards
Mark
