EGrove Posts: 3 Rating: (0)	Hi , I am a newcomer to LOGO programming ( have a couple of OBA6.ES3 + AM2 RTD).. I need the temperature of an aluminium part to ramp up from 30°C to 70°C at a rate of 0.3°C per minut. - and then stay at 70°C. Inserted in the aluminium block I have a Pt100 and a 24V heating element. It must be a trivial problem, and there might be a simple example of this somewhere in this forum, but I was not able to find it. Best regards Erik

Just take a puls and a counter to make te Setpoint of the PI reg. Look at the attachment. It need some adjusting for your personal oven. And the temp setting is not exact 0,3 deg/sec but 0,3 deg/1,01sec Attachment Slowtemp.zip (373 Downloads)

EGrove Posts: 3 Rating: (0)	Thanks a lot for your fast help ! If I see right - it ends up in an Analog output .. but I rather need a relay coil end - tocut in / and cut out the heat element... until the Pt 100 is satisfied .. along the ramp up... best regards Erik
