Objects Tab
Objects tab card is used to define all parameters of I/O points. Each device as its own object list.
First object of every device is used as the communication status signal of the device. If its value is “1” then communication with this device is broken.
Columns: Type – Object’s type: digital input (DI), digital output (DO), analog input (AI), counter (CN) Sub Type^ – Object’s subtype for uplink.
DI digital input: Single Double DO digital output: Same as Sub Type v
AI Analog input Normalized Floating point Step position
Sub Type v – Object’s subtype for downlink.
DI digital input: Normal Fallback DO digital output: Direct Execute Select Execute AI Analog input
Invert: Object’s value will be inverted Fn.code: Function code on the IEC 60870-5-103 protocol Info no: Information number on the IEC 60870-5-103 protocol Index: Object index on the IEC 60870-5-103 protocol. It indicates the order number of the object in message types 3 and 9 of analog measurements. In IEC 60850 used to match “Integer and Enum Values” for example AutoRecSt=”Successful” index should be 3. Object.Addr:Object’s downlink address 61850 v: 61850 address (loaded from device’s XML file), can be modified manually. Object.Addr ^: Object’s uplink address It is possible to send the same object to control centre with different addresses by creating several object with identical downlink addresses and different uplink addresses. Comment: comments of devices DB %Fs: Deadband (% of full scale, Outp.max-Outp.min). If the value has changed less than the deadband then it is not spontaneously transferred. Inp. Min, Inp. Max: Minimum and maximum values of analog measurement (before scaling). Necessary when value scaling is needed. (floating point to normalized) Outp. Min, Outp. Max: Minimum and maximum values of analog measurement. Necessary when value scaling is needed. (normalized to floating point) Forb. Ports ^: Uplink port to which the object’s value transfer is blocked. To select uplink ports, which should not be used for transferring these object values, double-click on the cell of the Forb. Ports^ column and select the corresponding ports from the window that has appeared. On Ev. Nr; Off Ev. Nr: Corresponding event number used in SPA-bus Ch. Nr.: Channel nr. for SPA-bus communication protocol NoFlags: If set to Yes, removes Invalid and Not Topical flags from object status. Used for objects, which statuses are not received with General Interval time (short circuit current, fault distance etc.)
Adding Objects By clicking on the „+“ button, a new object with default settings is added. Objects can also be added with a right click on the device tab card. Extended control menu appears where user can choose number of objects to add, into which device objects will be added, where in the list the object will be located, user can also choose if new object will be with default setup or copy some other object.
Removing Objects To remove a object, click the „-“ button. Objects can also be removed with a right click on the device tab card. Window appears where user can choose which objects to remove.
Hints • Repeated object addresses are shown on yellow background. • Lower lewel object can have multiple Object.Addr ^, duplicate object parameters and add new Object.Addr ^
