Reading Ladder PLC Programming for Heater Controller :
Step 1 :
a.If X000 = ON Then M0 = Momentary ON ( Pulse ).
b.If M0 = ON And X000 = ON And M2 = OFF Then M1 = ON ( Hold ON ).
Step 2 : Check Alarm Heater
a.If X001 = ON And M1 = ON Then T0 Activated.
b.If T0 = ON And X002 = OFF Then SET M2 = ON ( Hold ON ).
c.If X000 = OFF Then RST M2 = ON ( M2 = OFF ).
See Picture to Set Value Timer for Stability Current from Power to Heater :
Step 3 : Temperature is Reached
a.If X001 = ON And M1 = ON And X000 = ON And M2 = OFF Then M3 = ON ( Hold ON ).
b.If X001 = OFF And M3 = ON Then SET M4 = ON ( Hold ON ).
c.If M1 = OFF And X000 = OFF And M2 = ON Then RST M4 = ON ( M4 = OFF ).
Step 4 :
a.If M1 = ON Then Y000 = ON.
b.If M2 = ON Then Y001 = ON.
c.If M4 = ON Then Y002 = ON.
