Biasing And Terminating The Cm01 Signal Board; Using Hmi Devices On Your Rs485 Network - Siemens Simatic S7 Series System Manual

8.6.4.7

Biasing and terminating the CM01 signal board

You can use the CM01 signal board to easily connect multiple devices to a network.
The signal board passes all signals (including the power pins) from the S7-200 SMART CPU
through to the programming port, which is especially useful for connecting devices that draw
power from the S7-200 SMART CPU (such as a TD 400C).

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.
