3.1 Product overview
In this chapter
we shall introduce the major components for your S7-300 configuration.
S7-300 Configuration
An S7-300 consists of the following modules:
• Power supply (PS)
• CPU
• Signal modules (SM)
• Function modules (FM)
• Communication processors (CP)
Multiple S7-300 CPUs can communicate with each other and with SIMATIC S7
PLCs across PROFIBUS cable.
You require a programming device (PG) to program the S7-300 PLC. Interconnect
the PG and the CPU with a PG cable.
The figure below shows you a possible configuration, consisting of two S7-300
PLCs.
