Using HMI devices on your RS485 network

Introduction
The S7-200 SMART CPU supports many types of RS485 HMI devices from Siemens and
also from other manufacturers. While some of these HMI devices (such as the TD400C) do
not allow you to select the communication protocol used by the device, other devices (such
as the KP and TP product lines) allow you to select the communication protocol for that
device.
Guidelines
If your HMI device allows you to select the communication protocol, consider the following
guideline. For an HMI device connected to the communication port of the CPU, with no other
devices on the network, select the PPI protocol for the HMI device.
For more information about how to configure the HMI device, refer to the specific manual for
your device (see the following table). These manuals are included in the
STEP 7-Micro/WIN SMART documentation CD.
