• Please note! The resistance value of the NTC resistor decreases with increasing temperature.
Therefore, the maximum temperature value is the smallest value for AX. At this limit value, the blower
is to be turned. The lower temperature limit is the biggest value for AX. At this limit value, the heating
is to be turned.
• With the interface test, you can find out what value AX has at room temperature. Turn on the indicator
light, M2, and observe how much the value decreases. Now turn on the blower and find out how much
the value increases. Based on this, select the limit values for heating and cooling.
• Display the value of the analog input in your program with the display of a text and/or with a
measuring instrument (see ROBO Pro Handbook chapter 8.1).
• Sample program: Temperature control.rpp
The shop next door has invested in a
very modern machine for the punching of
sheet metal parts. The machine has been set up
already. Unfortunately, the programer, who was to place the
system in operation, will not arrive until two weeks from now. Since
the shop urgently needs the machine, the owner asks you if you would be able
to make the machine run. Since, in the meantime, you have gathered quite a lot of experience in
programing, you promise him to have the system running by tomorrow.
First, build the model stamping press using the construction instructions.
Ta s k 1 :
The machine is to punch a part in one working cycle with four strokes.
The machine may only start when the operator pushes both buttons I3 and I4 (two-
hand operation) and the light barrier is not interrupted.
If the light barrier is interrupted during the working cycle, the machines stops.
P r o g r a m i n g Ti p s :
• To interrogate the inputs I2 (light barrier) and I3 and I4 (buttons) at the same time, use the orange input
elements and an AND link (see ROBO Pro Handbook chapter 5.7).
• To count the four strokes, use the counter loop element.
