To create a new device, select [Tools] → [I/O Devices] or click the icon in the toolbar. The following picture shows the first step in creating a new device:

I/O Device Name: Give a device name. This name will be used in the tag database, accompanied by the ‘Station Name’.

After selecting the [Ok] button in the previous step, the ‘Serial communication Configuration’ dialog box will appear as shown in the following picture:

In this window, set the 'Device Type' to ‘SIEMENS S7 PPI Direct’ and configure the remaining communication parameters. These parameters must match those chosen for the PLC.

The parameters should be set to the following values:

Baud Rate: 9600 or 19200 (must be matched with the PLC)
