OPC EIE – UIS Command Component Parameters

UIS Command Component Parameters

The following tables list and describe the parameters specific to the UIS command component types for this remote device:

CYUPDTPT
CYWAITPT
DG_F_DEV
DG_T_DEV

For more general information about UIS command component parameters, see UIS Command Components. The DG_F_DEV (Get data group from device) and DG_T_DEV (Send data group to device) command component types are configured in the template file. The other command component types are considered ‘special’ and are defined in the EIE editor code. See Special UIS Command Component Types for more information.

CYUPDTPT

Update CygNet Point updates the record for a CygNet point. CYUPDTPT has the following command parameters:

Parameter	Required	Description
FOnErr	No	Fail cmd on update error indicates to abort the UIS command if any update errors are encountered. The errors that might come up include: if the point specified in the Fac, Serv, Site, or UDC parameters does not exist, or if the point exists in a different UIS and any messaging errors or communication failure to that service comes up.
Fac	Yes	Facility for pt identifies the facility of the point to update.
Serv	No	Service for pt identifies the SERVICE of the point to update.
Site	No	Site for pt identifies the SITE of the point to update.
UDC	Yes	UDC for pt identifies the UDC of the point to update.
UType	No	Update type indicates the type of update. Value options are 0 - 3, where 0=Completion, 1=Success, 2=Failure, 3=Creation.
UsrMsk	No	User bit mask specifies the user bit mask of the point to update.
UsrVal	No	User bit value to match specifies the user bit value to match when updating the point record.
Value	No	Value indicates the point value to update.

CYWAITPT

Wait for CygNet Point signals the UIS to wait to perform a command until the value of the specified CygNet point changes to a specified value.

CYWAITPT must be the first command component added to a UIS command. You cannot add other instances of CYWAITPT to a UIS command.

CYWAITPT has the following command parameters:

Parameter	Required	Description
Dur	Yes	Duration is the amount of time (in HH:MM:SS or HH:MM or HH) for the UIS command to wait for the point value to change before timing out.
FOnErr	No	Fail on point error indicates to abort the UIS command if any error conditions are encountered. The point errors that might come up include: if the point specified in the Fac, Serv, Site, or UDC parameters does not exist, or if the point exists in a different UIS and any messaging errors or communication failure to that service comes up.
Fac	Yes	Facility for pt identifies the facility of the point on which to wait for the point value to change before performing the UIS command.
Int	Yes	Interval indicates the frequency (in HH:MM:SS or HH:MM or HH) with which the UIS will check the point’s value to see if it has changed.
Serv	No	Service for pt identifies the SERVICE of the point on which to wait for the point value to change before performing the UIS command.
Site	No	Site for pt identifies the SITE of the point on which to wait for the point value to change before performing the UIS command.
UDC	Yes	UDC for pt identifies the UDC of the point on which to wait for the point value to change before performing the UIS command.
UsrMsk	No	User bit mask specifies the user bit mask on which to wait for the status bit change before issuing the UIS command. Note: The user status bit parameters (UsrMsk and UsrVal) only apply to the extended status field of the point record, so they will not match anything in the base status.
UsrVal	No	User bit value to match specifies the user bit value to match before issuing the UIS command.
Value	No	Value to match specifies the value on which to wait for the point to change to before issuing the UIS command. Note: You can set parameters for both the point user status AND point value. So you can match either one by itself, or you can specify that both must match your parameter values.

DG_F_DEV

Get data group from device retrieves a data group from a field device. The Parent XML Element is uccRecvParms. See OPC Data Groups for more information about getting data from the device or the cache.

The following parameters are available for each specified data group type.

Data Group Type	Parameter	Required	Description
CfgDg	ReadDevice	No	False=from cache; True=from device A one-time read of an item's value data from the CygNet device or the OPC server's cache. Note: The read from the cache is always synchronous. Value options are Boolean.
CfgDg	SyncIO	No	False=async; True=sync IO Applies only to reads from the device. Value options are Boolean.
SingleItem	Desc	No	Description Value options are strings.
	FacUdc	No	Facility.UDC for Point Processing provides a means to specify a UDC to which to map the specified data point; it requires a corresponding point in the Point Service (PNT). Value options are strings that specify a Facility.UDC combination.
	ItemId	Yes	Item ID is the item identifier as defined on the OPC server. Value options are strings.
	ReadDevice	No	False=from cache; True=from device A one-time read of an item's value data from the CygNet device or the OPC server's cache. Value options are Boolean.
	SyncIO	No	False=async; True=sync IO Value options are Boolean.

DG_T_DEV

Send data group to device sends a data group to a field device. The parent XML Element is uccSendParms. The following parameters are available for each specified data group type.

Data Group Type	Parameter	Required	Description
SingleItem	DataType	No	Data type defines the type of data stored at the specified item ID. Value options appear in the Data type drop-down list in the Single Item data group dialog box.
	Desc	No	Description Value options are strings.
	FacUdc	No	Facility.UDC for Point Processing provides a means to specify a UDC to which to map the specified data point; it requires a corresponding point in the Point Service (PNT). Value options are strings that specify a Facility.UDC combination.
	ItemId	Yes	Item ID is the item identifier as defined on the OPC server. Value options are strings.
	Value	Yes	Value defines a value to be sent to the specified item. Value options are floating-point numbers.
