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 three types of supported hardware channels.
• Binary input channels
• Binary output channels
• Analog input 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.

Online monitoring

The online monitoring enables the continuous monitoring of the signal or channel values
in the configuration. In the "Online monitoring" mode, the configuration cannot be edited
in the Application Configuration tool.
