SIMATIC TD 200 Operator Interface
C79000-G7076-C272-01
B.1 Configuring for Multiple CPU Communication
Figure B-1 shows a typical network. In this figure there are two TD 200s and two
CPUs. Each TD 200 communicates to one of the CPUs. The addresses of each
device are noted below the device in the figure. Refer to Section 3.8 for information
about how to set an address in the TD 200. Refer to the CPU programming
software documentation for help in changing the address of the S7-200 CPU.
In this example, the TD 200 Number 1 is configured to communicate to the CPU at
address 2 (CPU Number 1), and TD 200 Number 2 is configured to communicate
to the CPU at address 3 (CPU Number 2).
Note
You can connect multiple TD 200s to a single CPU. You can store separate
parameter blocks for each TD 200 in different V memory locations in the CPU.
See Sections D.1 and 3.8 for more information. If you do not store separate
parameter blocks for each TD 200 that is connected to the CPU, any of these
TD 200s can acknowledge the same messages and use function keys to initiate
operations in the CPU.
