The S7-1200 CPUs with Safety Integrated handle both standard and safety-related tasks. A compact design with integrated IO, communi-cation interfaces that meet the highest industry requirements and a range of powerful integrated technological functions make this controller an integral part of a comprehensive automation solution.
The compact SIMATIC S7-1200 system consists of different CPU performance classes: CPU 1211C, CPU 1212C, CPU 1214C, CPU 1215C and CPU 1217C and the failsafe versions CPU 1212FC
CPU 1214FC and CPU 1215FC. Each of these may be expanded according to the machine requirements. The S7-1200 CPUs can be expanded with up to three communication modules (CM) and eight signal modules (SM).
Signal modules and signal boards can be integrated in order to expand the digital or analog IOs without affecting the physical size of the controller.
Signal modules can be connected to the right side of the CPU to further expand the digital or analog IO capacity. CPU 1212C accepts two, CPU 1215C and CPU 1217C accept eight signal modules.
All SIMATIC S7-1200 CPUs can be equipped with up to three communication modules on the left side of the controller – this enables seamless serial communication and the use of various distributed IO devices.
