The technological functions for the SIMATIC S7-1200 are available with STEP 7 Basic as well as STEP7 Professional.
The SIMATIC S7-1200 supports up to 16 PID control loops for simple process control applications. These control loops are easily configured using a PID controller technology object and the supporting editors provided within the engineering system STEP 7.
Two different PID controller algorithms are available in the S7-1200:
Additionally, the SIMATIC S7-1200 supports PID auto-tuning to automatically compute the optimum tuning values for the gain, integral time and derivative time.
PID commissioning control panel
The PID commissioning control panel included within SIMATIC STEP 7 simplifies the loop tuning process. It provides both automatic tuning and manual control capabilities for a single control loop and it also provides a graphical trend view of the tuning process.
PLCopen motion function blocks
The SIMATIC S7-1200 supports the open-loop speed and position control of stepper motors and servo drives. This functionality is easily configured using an axis technology object along with the internationally accepted PLCopen motion function blocks included within the engineering system SIMATIC STEP 7. Absolute, relative and velocity moves are supported in addition to home and jog functions.
Drive commissioning control panel
The drive commissioning control panel included with the engineering system SIMATIC STEP 7 simplifies the start-up and commissioning of stepper motors and servo drives. It provides both automatic and manual control of a single motion axis as well as online and diagnostics information.
