Product Type:
PLC's

Brand & Model nr:
Siemens S7-200

Solution Overview:
The example shows how to connect a Siemens S7-200 to Profibus. The Anybus Communicator is used to connect between Profibus and the S7-200 port 0. The Anybus communicator will act as a master and the S7-200 will act as a Modbus RTU slave on the sub-network.

Solution Brief:
The Siemens S7-200 has to be configured for serial communications. On the CD Step7-Micro/WIN, order number 6ES7 830-2BC00-0YX0, there are pre-configured subroutines and interrupt routines that will make the S7-200 act as a Modbus slave. In this example we have used the following settings for the pre-configured subroutine:
Baudrate = 9600
Mode = 1
Parity = 0 (None)
Address = 1
Delay = 0
MaxIQ = 16
MaxAI = 0
MaxHold = 0
HoldStart = &VB0

The Anybus communicator is set up with the following settings on the sub-network:
Baudrate = 9600
Data bits = 8
Parity = None
Stop bits = 1
Physical standard = RS232

The configuration, for the Anybus communicator, uses two commands. Read input status reads 8 bits and Force Multiple Coils writes 8 bits.


Serial cable:
The cable used between the Anybus communicator and the Siemens S7-200 is the RS232/PPI Multi-Master cable. (The dipswitch has to be set to: 01000010, when connected to the Anybus communicator)

Comments:
The configuration for the Anybus communicator can be used for different fieldbus types. Change the Fieldbus type in the configuration and download to the same type of communicator.
