Swing Door Asset Type Example

By default, PLC Devices has a Swing Door asset type. This asset type serves as a good example or template of how to use PLC Devices in projects.

Swing Door

After adding PLC Devices to your project, the Swing Door asset can be found under Asset Types. The Asset Type Settings will be as follows:


1. Asset Type Settings	Displays the default settings for an asset's name, caption color, and size for the Swing Door asset.
2. Element Properties	Displays each of the element's properties needed for this project. This will include the logic needed to make the Swing Door asset work.
3. Icon Preview	Displays how the icon will appear.
4. Elements	Displays the different elements within this asset icon. Some elements like Door Frame are used to create the icon but do not serve a functional purpose.

Table 1. Elements
Friendly Name	Expression	Description
Open	Status Word:Open	Shows that the door is open regardless of whether the current Workstation controls it.
Closed	Status Word:Closed	Shows that the door is closed regardless of whether the current Workstation controls it.
Door Frame (Always Visible)	Empty	This element is always visible to show the general shape of the door icon.
Masked	Current Asset:Is Masked	Changes the background of the icon to a cream color and masks incoming alarms.
Door Held Open	Status Word:Door Held Open AND Custom Attributes: WorkstationInControl	Changes the background of the icon to a bright yellow. This element is bound to an alarm and will flash when visible. Note: This element must be assigned to an alarm type for it to appear in Runtime.
Door Forced Open	Status Word:Door Forced Open AND Custom Attributes: WorkstationInControl	Changes the background of the icon to a bright orange. This element is bound to an alarm and will flash when visible. Note: This element must be assigned to an alarm type for it to appear in Runtime.
PLC Error	Current Asset:Status Word Value<=0 OR Current Asset:Status Word Value>=8192	Changes the background of the icon to dark purple to indicate an unknown PLC value.
No Communication	Current Asset:Is No Communication	Changes the background of the icon to light purple to indicate that IPFusion cannot communicate with the PLC object.
Unsecure	(Status Word:Strike Output OR Status Word:Open) AND Custom Attributes:WorkstationInControl	Changes the background of the icon to red to indicate the door is currently unlocked. Note: This element is only visible if the Workstation is in control of the door represented by the WorkstationInControl Custom Attribute.

Asset Attributes

Under Assets Attributes is an example of setting up a Status Word chart. This will vary depending on your project, but in this specific case, five bits will be used to enable the asset to function. Only one Custom Attribute is required for this asset, and that is to grant access to a specific Workstation.


1. Status Word	Displays each bit in a Status Word, along with its Bit Position and Friendly Name.
2. Custom Attributes	Displays the Attribute Name, Data Type and Initial Value of the Attribute.

Table 2. Status Word Chart
Bit Position	Friendly Name	Description
0	Closed	Signals that the door is closed.
1	Open	Signals that the door is open.
2	Strike Output	Signals the door to unlock.
11	Door Forced Open	Signals that the door is forced open.
12	Door Held Open	Signals that the door is held open.
