When a hardware channel is connected, a graphical symbol appears in the Application
Configuration tool. The connection is also indicated in the Signal Matrix tool with a
cross mark. Hardware channels are always visible in the Signal Matrix tool.

Figure 47: Application Configuration tool: HW signal channels
There are three types of supported hardware channels.
• Binary input channels
• Binary output channels
• Analog input channels
A hardware input channel can be used as often as needed. A hardware binary output
channel is taken from the list of available channels when a new channel is requested.
This prevents using the same hardware binary output channel twice.

User-customized I/O channel configuration

Instead of pre-configured I/O channel connections to pre-processing function blocks,
user-customized configurations can be used. There are some rules which must be
followed to create a working configuration. Application Configuration automatically
checks if configuration is valid and results are shown in the output pane. See the
technical manual for the minimum I/O requirement per application function block.
