The CPUs are each presented in five different variations, with various connection and manage voltages. the PPI interface constructed into all CPUs enables factor-to-factor connections to pg/pc, SIMATIC op, expanded SIMATIC s7-200 and user-described cease gadgets (printer, bar code reader). with pg/pc or op as master, a most of 31 SIMATIC s7-200 devices may be connected collectively. if additional inputs/outputs are required, a spread of various expansion modules is available. those are actually connected to the CPU through a connector.
