Both have 2 PN ports that can be used either as HMI connection and switchless I/O or as one programming and one field device port.
SIMATIC S7-1200 Integrated technologies Integrated technology for counting and measuring, closed-loop control and motion control make the SIMATIC S7-1200 an extremely versatile system for many types of automation tasks.
1211C, 1212C, 1214C with high-speed outputs to control speed, position
and duty cycles
The high-speed outputs of the SIMATIC S7-1200 controller can be used as pulse train outputs (PTO) and pulse width modulated (PWM) outputs. When configured as a PTO, a 50 percent duty cycle pulse train is provided at a rate of up to 100 kHz for the open-loop speed and position control of stepper motors and servo drives. When these Outputs are configured as a PWM output, a fixed cycle time output with a variable duty cycle controls can be used to control the speed of a motor or position a valve for instance.
1215C and 1217C high-speed outputs control speed, position and duty cycles
The SIMATIC CPU 1215C and CPU 1217C features six high-speed counters (HSC) build in – three with a clock rate of 100 kHz and another three with a clock rate of 30 kHz, using the readily available Signal Boards up to 200 kHz can be achieved as well. Furthermore there are four PTO outputs to control stepper drives simultaneously.
The new SIMATIC S7-1217C covers even more motion applications with the addition of the 5V Line Diver outputs.
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 Basic. Absolute, relative and velocity moves are supported in addition to home and jog functions.
