The DigitalOutput component is an IO point (network point class) component that transfers the value to a physical digital output of a device. The component allows to transfer data received from the linked Data Point in order to control the physical digital output of the device. The component can pass data from the Data Point class component by linking Reference slots; the DigitalOutput component may be linked from a Binary Data Point. In order to operate properly, the DigitalOutput component must be located under the Local IO component in the Networks container.
Note: Before using the component, make sure that its individual address is assigned and its Status is OK.
The DigitalOutput component includes an action that allows to set its Out value in case no Data Point class component is linked to it.
The DigitaIOutput component has the following slots:
- Status: indicates the current status of the component; if the component works properly, its status is OK. The component becomes Disabled, once the Enabled slot is in false. The component's status is Fault, once the Address slot is null, 0, or exceeding an available range;
- Available information: Disabled, Fault, OK;
- Reference: a special slot allowing to connect network point class components with Data Point class components. It allows to transfer the Out slot value along with the component's status.
Note: Reference links from Data Points to network points also transfer values in the opposite direction, in a link-back-from process: having received a value by the Reference link, the network point transfers it back to the Data Point to whichever input priority from 1 to 16 is set in the network point.
Note: The Reference links work on a change-of-value. If a value in the Data Point's Out slot changes, it is immediately transferred to a network point linked by the Reference link–such change is not dependent on an application cycle.
- Description: an additional detailed information about a component that may be freely described by the user; the description may contain individual coding, defined in the user's system documentation, meter's or sensor's location, or any other information the user finds applicable.
- InputPriority: allows to indicate the input number in the Data Point, which the network point class component's output value is sent to, in case the network point detects the change on its Out slot; by default, the priority is set to none.
- Available settings: none, 1-16.
- Polling Mode: allows to set the frequency of sending polling requests for the point's value—by default, the polling mode is set to normal;
- Available settings: fast, normal, slow;
- Enabled: change of the slot's value enables or disables the component—if the component becomes disabled, it stops to transfer values to the physical output; by default, the component is enabled.
- Available settings: true (enabled), false (disabled).
Note: If the Enabled slot is in false (meaning the component is disabled), the Status slot becomes Disabled.
- Out: displays a value transferred to the output of the address set in the Address slot.
Note: If the component's Status is fault (e.g., an invalid value in the Address slot), the Out value is null.
- Address: allows setting an address of a physical output of the device; once the component has been added, the slot's default value is null—for the component to operate properly, the unique address value must be set in this slot.
- Available settings: 1-n, where "n" stands for the number of actual outputs in the device.
The DigitalOutput component has the following action:
- Set: sets a value to the Out slot—in case no Data Point is linked to the output network point, it is possible to set its Out value with this action.
