SIMATIC TD 200 Operator Interface
C79000-G7076-C272-01
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
!
Warning
The TD 200 may only be connected to grounded voltage sources. Non-grounded
operation can lead to damage to the device.
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 1-8 shows a one-to-one configuration. The TD 200 communicates to and is
powered by the S7-200 CPU using the TD/CPU cable.

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.
The TD 200 defaults to address 1 and attempts to communicate to a CPU at
address 2. If you use other addresses, see Section 3.8 to change the network
address.
