4. Delete the third network of the organization block "Main [OB1]".

This program segment is no longer necessary because the on/off control of the heating

chamber takes place via the program for controlling the machine in the first network of the

organization block.

5. Delete the fourth network, in which the status lamp of the heating chamber is

programmed. The status lamp is no longer necessary, because operation of the heating

chamber takes place parallel to operation of the machine.

Result

You have programmed the on/off control of the heating chamber so that the heating chamber

is operated parallel to the machine.

In the next section you will program a query of the temperature values and integrate it in the

program as condition for control of the conveyor.
