Connecting The Td/Cpu Cable - Siemens S7-200 System Manual

The standard TD faceplates are shown in Figure 1-2. The TD 200C comes configured as a
standard TD 200 (with LEFT and RIGHT arrows). The TD 100C comes configured with six
standard keys (UP, DOWN, LEFT and RIGHT arrows, ESC, and ENTER). The TD400C
comes configured with seven standard keys (UP, DOWN, LEFT, RIGHT, ESCAPE, ENTER,
and SHIFT).
After creating and installing the custom faceplate on your TD device you must also download

NOTICE
Operating the TD device with an ungrounded voltage source can damage the TD device.
The TD device may only be connected to grounded voltage sources. Non-grounded
operation can cause the TD device to become damaged.
Always ensure that the voltage source for the TD device is properly grounded.
The TD devices can use the TD/CPU cable for communicating with the S7-200 CPU.
● You can connect the TD device directly to the S7-200 CPU, creating a one-to-one
● You can connect multiple TD devices to multiple S7-200 CPUs over a network. The TD
For more information about connecting to multiple CPUs, see Appendix B. For information
about changing the default addresses in the TD device, see Chapter 5.
If you require a longer cable (>2.5 m) to connect the TD device to the S7-200 CPU, use
PROFIBUS components for the network connection. Refer to the SINEC IK10 Catalog.
