Do you need a low-cost motion controller for more than 4 step or servo motors for simple non-coordinated moves?  Do you need to control several valves or dispense fluids precisely?

Siemens has a solution!

Combining Siemens’ S7-1200 PLC with their SIMATIC PN/CAN Link (6BK16200AA000AA0) gives you the ability to control multiple step or servo motors with a low-cost PLC.

For example, your motor of choice is a Nanotec Smart Servo PD4, which is an integrated motor containing a controller and encoder.  This motor can operate as a servo motor or a step motor.  You can use up to 8 PDO’s (similar to read-write registers) on each motor and the PN/CAM Link can address 512 PDO’s.  Theoretically, you could control 64 motors.  However, you would be limited by the amount of PLC memory you use.

Here are the major components:
