Description

Verion 5

This adapter supports up to 4 target addresses, which must be defined in the configuration dialog.

Verion 3

This adapter supports only one target address. If there are different Net addresses to communicate with, the driver will reconfigure the adapter. This reduces the transmission rate, however. Communication is possible with all addresses within the defined address area (HSA).

Helmholz SSW7-HMI

This adapter supports only one target address. If there are different Net addresses to communicate with, the driver will reconfigure the adapter. The driver supports the Helmholz-specific command extensions, which accelerate the changing of the target address. Communication is possible with all addresses within the defined address area (HSA).
