The SIMATIC S7-200 family offers a broad spectrum of modules suitable for the most varied applications. The newly available CPU types and expansion modules enable universal automation concepts with 10 to 248 inputs/outputs. The products of the S7-200 family which are optimally matched to each other also make it easy to change and expand the automation solution in the future. Application areas such as:small and special machine construction: packaging, strapping and coiling machines · food industry: kneading, cutting machines, mix granulating machines · laboratories: laboratory mixers, heating cabinets, vacuum pumps, suction equipment.The CPUs are each offered in 5 different variants, with various connection and control voltages. The PPI interface built into all CPUs enables point-to-point connections to PG/PC, SIMATIC OP, expanded SIMATIC S7-200 and user-defined end devices (printer, bar code reader). With PG/PC or OP as master, a maximum of 31 SIMATIC S7-200 devices can be connected t
