temperature set point

[liey_v12]

hello...

PLC Type: DL-06
Using DirectSOFT 5 software

i was make connection between PT100 and F0-04RTD I/O,
temperature value show around 31°C,

my question is how to make 27°C for temperature set point?,
because i want to control the temperature using intercooler and heater if the value is higher and lower than set point.

tq...

you can use the comparison instructions

that is mean you have minimum set piont and maximum set piont

if you have one set piont you must use PID control to achive the required set piont

Really you don't, there are other ways than PID to control heat and cooling. What do you think we did before PID (roll your own).

Can you explain the other ways than PID to control this temperature.
PID is quiet complex to learn.
Some example if any.

I think you can use a PID

You can also use compare instruction. Use LEQ and GRQ and set a set point.
