The Siemens Drivers module allows you to connect to a number of Siemens S7 devices. The available device drivers are:
UDP and TCP Drivers
The UDP and TCP Drivers module are very basic drivers that can connect to one or more ports of a given IP address and read in data. This is typically used for barcode scanners or scales.
The DNP3 Driver module allows you to connect to a DNP3 outstation. Many different types of devices support DNP3.
There are a number of drivers that do not connect to any device, but instead provide simulated values for testing. These simulators are a part of the Allen Bradley Driver module.
