Setting the baud rate and network address for the S7-200 SMART CPU

Introduction

To communicate over the RS485 network with STEP 7-Micro/WIN SMART or SIMATIC HMIs

(Page 398), you must configure the RS485 network address and baud rate for the

S7-200 SMART CPU.

The RS485 port network address must be unique for all devices on the RS485 network, and

the RS485 port baud rate must be the same as the other devices on the RS485 network.

The default RS485 port network address is 2, and the default RS485 port baud rate for each

CPU port is 9.6 Kbps.

The system block of the CPU stores the RS485 port network address and baud rate. After

you select the parameters for the CPU, you must download the system block to the

S7-200 SMART CPU.

To access the "System Block" dialog, click one of the following:
