Communications Processors For Simatic S7 - Siemens SIMATIC NET System Manual

Communications processors for SIMATIC S7

Overview
For each SIMATIC S7 system there are communications processors that provide a
connection of a station (the so called system connection) to a communication network. This
means that S7 controllers can exchange data with other network nodes via Industrial
Ethernet or PROFIBUS. These network nodes can be other S7-CPs/CPUs or PCs with an
Ethernet card. This makes remote programming and diagnostics via the PG/PC possible.
With the communications processors that support PROFINET, PROFINET IO-compliant field
devices can be addressed directly.
