In this example, the device will be renamed S7300. Right-clicking the PLC and selecting “Rename” can

achieve renaming.

The device settings have to be set up to fit the PLC configuration (Figure 27).

1. Select the device representing the PLC.

2. Change the IP address to the CP 343 Lean IP address, in this example 192.168.200.20.

3. Select the Type as S7 300 CPU. The driver should behave as if it communicates with a CPU

directly since the CP 343 Lean is transparent.

4. Enter the CPU rack number (NOT the CP343), in this example 0.

5. Enter the CPU slot position on the rack (NOT CP343), in this example 2.

The communications settings are now complete. Close the “Communications” module and enter the “Data

Tags” module to map variables to PLC registers as shown in Figure 28. For example, to map a Data Block, do

the following steps:

1. Create an integer variable.

2. Select the variable, click on “Internal” in the Data tab and select the device (here S7 300).

3. Select the Siemens data item to exchange, here DB.

4. Choose the data type (See note on Data Type next page).

5. Select the starting element for the data item (Identical to PLC addresses) and click OK.

Once the tags are inserted on the screen, the database is now ready and can be downloaded in the G3.
