Application examples, 04/2022, AG022322

Navigate to the “PLC Tag” list under the “S7-400” PLC and double-click on it to open the tag

list. In the sample project, we have already created TAG names for the I and Q addresses.

Highlight the S7-400 from the main project tree and then select “Download to device” from

the “Online” menu.
