PID Temperature ControlIn addition to the universal PID Control
function blocks, STEP 7 offers two control blocks for the closed-loop control of
simple temperature loops (e.g. heater or cooler controls). This includes
parameterization software, a sample project and an electronic manual. The
parameterization software provides a wizard for self-optimization, a special
commissioning screen and can be directly started from the SIMATIC Manager

- A function block for temperature control features integrated online
self-optimization without a PG/PC. A pulse shaper is also integrated to
implement pulse controllers. In contrast to the solution using PID Control,
there is no need to connect control blocks - it is parameterized and not
programmed.
- An additional control block is used to create step controllers
