Communications processors for PCs

Overview
Communication processors for PCs/PGs allow you to establish a connection to Industrial
Ethernet with a PC/PG or a SIMATIC Microbox PC (PCI-104 interface). There are two
categories of communication processors for PCs/PGs:
● Communication processors with their own microprocessor
This relieves the PC/PG CPU. This frees up computing power on the PC for other
applications, for example, HMI (ISO and TCP/IP Transport on-board).
● Communication processors without their own microprocessor.
These communication processors are less expensive than the communication processors
that have their own microprocessor. If there is, however, a heavy load on the PC
microprocessor, it is possible that the protocol stack does not receive a time slice and this
leads to the connection being terminated. When communication processors with their
own microprocessor are used this does not occur.
