Accessing Siemens PLC through Ethernet

This section describes how to configure HMI units and Siemens PLC program so the HMI unit and Siemens PLC can communicate through Ethernet.

■ Creating a new link

To communicate with Siemens PLC, you need to create the following communication link for the HMI unit.

The driver of SIMATIC S7 (Ethernet) allows index addressing for data blocks. For examples, the addresses shown below are valid now.

DB[$I3].DBW100

DB[$I5+2].DBD[$I10+16]

DB[$I0+2].DBX[$I1].5

Note: The support of data block indexing can be provided for any PLC driver upon request.

■ Setting the link properties

To enable the communication, you need to set the Rack number and Slot number upon the Siemens PLC configuration. The following is an example which uses the default rack and slot number.

■ Making data blocks in the Siemens PLC accessible
To make the data blocks in the Siemens PLC accessible, all the data blocks in the program must have the "Symbolic access only" option unchecked. If the data block is symbolic access only, the HMI units will not be allowed to access the data blocks and the communication error will be shown up. The following is an example of a data block with "Symbolic access only" option unchecked.
