This driver uses a standard Ethernet connection to communicate with Siemens S7 devices.

Communication Settings: Xpanel

I/O Device Configuration

To create a new device, click Tools > I/O Device Editor… > click the + icon > click Ethernet for Connection Type > select Siemens S7 for Device Type.

I/O Device Settings

Once the connection type, device name, and device type have been assigned, the I/O Device Editor window populates with the default settings for the selected communication protocol.

After selecting the correct Connection Type and Device Type, match the remaining settings to the target I/O device’s communication settings.

See the Ethernet Communication Configuration section for more information.

S7 1200/1500 notes:

Only global DBs can be accessed.
To access a DB memory area in S7 1200/1500, some additional settings in PLC software (TIA Portal) is required.
The optimized block access must be turned off.
1) Select the DB in the left pane under “Program blocks” and press [Alt+Enter]. (Or in the contextual menu, select “Properties…”)
2) Uncheck Optimized block access
The access level must be “full” and the “connection mechanism” must allow GET/PUT.
1) Select the CPU project in the left pane and press [Alt+Enter]. (Or in the contextual menu, select “Properties…”.)
2) Select “Full access” and check “Permit acess with PUT/GET …” as in the image below.
