Product Overview and Installation
1.3
Connecting the Communication Cable
The TD 200 communicates to the S7-200 CPU through the TD/CPU cable. You can
configure the TD 200 using the TD/CPU cable in the following ways:
One-to-one configuration
Multiple S7-200 CPU configuration
Installing Cable for One-to-One Communication
Use a one-to-one network configuration when you have just one S7-200 CPU to connect to
one TD 200. A one-to-one configuration consists of a TD 200, an S7-200 CPU, and a
TD/CPU cable that is supplied with the TD 200.
Figure 1-5 shows you a one-to-one configuration. The TD 200 communicates to and is
powered by the S7-200 CPU using the TD/CPU cable.

One-to-One Configuration
Installing a Multiple CPU Network
Use a multiple CPU network configuration when you have several S7-200 CPUs to connect
to one or more TD 200s. For more information on configuring for multiple CPU
communication, refer to Appendix B.
Note
The TD 200 defaults to address 1 and attempts to communicate to a CPU at address 2.
See Section 3.8 to change the network address if other addresses are used.
