The SSW5/USB converter cable is for connection of a Simatic S5 CPU to a PC with a USB interface. For PCs that do not have a serial interface, the SSW5/USB cable can connect to the PLC via a virtual COM port. A virtual COM port is set up during installation of the SSW5/USB. It can then be used by programming software, such as Siemens Step 5 Version 7.2x, Deltalogic Accon programming software or other programming systems for the Simatic S5.
Use of the SSW5/USB with visualization systems that can be connected to the S5 CPU is also possible.

Installation of the USB driver
If a SSW5/USB is being connected to the PC for the first time, the operating system will try to install a suitable driver. This driver provides the interface between the USB interface and the operating system (Windows). Moreover, the software for the virtual COM interface must be installed and set on the PC. Initial installation of the USB driver can take some time and goes through the following steps:
- The operating system starts an installation wizard that performs the installation, which is automatic.
- The next step is a prompt to specify the location of the driver.
- The system now searches for the driver…
- If the SSW5/USB CD is inserted in a local drive, installation should start after a short time.
- After successful installation, the operation is completed by clicking the “Finish” button.
Here it is necessary to specify that the source for the USB driver should not be ascertained automatically.
It is generally enough to set a checkmark next to ‘Search removable media…’ and then to click the ‘Next’ button.
Installing a virtual COM port
The CD supplied with the SSW5/USB contains the setup for the virtual COM port software. Run the setup and follow the instructions given. The computer must be rebooted after you have installed the software. The program can be started via “Start / Programs / Systeme Helmholz / SSW5-USB”. After you have started the program, you will see it in the taskbar.
Settings for the virtual COM port
The COM port to be used by the SSW5/USB can be defined in the properties of the COM port driver. To use the SSW5/USB with Step 5 from Siemens, you should select a port between COM1 and COM4.
