Hardware channels

Hardware channels can only be connected to a function block input or output. A
hardware connection can be established with the Application Configuration tool or
Signal Matrix tool.
When a hardware channel is connected, a graphical symbol appears in the Application
Configuration tool. The connection is also displayed in the Signal Matrix tool with a
cross mark. Hardware channels are always visible in the Signal Matrix tool.
There are four types of supported hardware channels.
• Binary input channels
• Binary output channels
• Analog input channels
• Analog output channels
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.
