I/O Menu

I/O/Channel Settings

Built-in I/O is an optional hardware feature on cnReach models. See the product overview section for

the sales models that include built-in I/O. The built-in I/O can be used to interface directly to analog

and digital service (inputs and outputs). Refer to the technical reference section for more details and

wiring examples of the I/O interfaces.

GUI settings for the IO1 to IO4 referencing Analog I/O:

- Analog input current-sense/pull-down resistor. Turning this on enables the pull-down resistor.

See reference schematic in the technical reference section.

- The Analog default command sets the default amount of current to drive in an analog output

application.

- The Analog safety action is what the cnReach radio will do if no Modbus command is received

within the Modbus timeout setting (see the Modbus settings page).

- The Analog output fault action is what to do if the cnReach radio attempts to drive analog

current into a short circuit or other fault condition. cnReach can either continue to retry or

simply clear the command / Modbus register setting.

GUI settings for the IO5 to IO8 referencing Digital I/O:

- Digital input pull-up resistor. Turning this on enables the pull-up resistor which is commonly

used with dry-contact switch applications. See reference schematic in the technical reference

section.

- The Digital output default command sets the default state to drive.

- The Digital output safety action is what the cnReach radio will do if no Modbus command is

received within the Modbus timeout setting (see the Modbus settings page).

- The Digital output fault action is what to do if the cnReach radio attempts to drive into a short

circuit or other fault condition. cnReach can either continue to retry or simply clear the

command / Modbus register setting.
