UA_MonitoredItemAddList |
|||
|
This Function Block can be used to add handle of multiple nodes using a list of node handles. |
||||
|
VAR_INPUT |

|
B |
Execute |
BOOL |
On rising edge monitored items will be added to a subscription. |
|
|
B |
SubscriptionHdl |
DWORD |
Subscription handle. |
|
|
B |
NodeHdlCount |
UINT |
Number of valid elements in the array to add. |
|
|
B |
NodeHdls |
ARRAY OFDWORD |
Array of Node handles. Max length of array is to be defined by the vendor and shall be same length thanVariables array length. Shall be the same size as NodeHdlCount. |
|
|
B |
SyncMode |
UAMonitoringSyncMode |
See chapter 4.2 Monitored Items for general concept of SyncModes
|
|
|
B |
NodeAddInfos |
ARRAY OFUANodeAdditionalInfo |
See UANodeAdditionalInfo. Specifies the attribute and IndexRange. See Constants of Array Lengths (MAX_ELEMENTS_MONITORLIST) This parameter is optional. If not existing, the UAAI_Value (13) will be taken from internal implementation. |
|
|
B |
Timeout |
TIME |
Time to response. |
|
|
VAR_OUTPUT |
||||
|
B |
Done |
BOOL |
FB has completed its task. |
|
|
B |
Busy |
BOOL |
The FB is not finished and new output values are to be expected. |
|
|
B |
Error |
BOOL |
Signals that an error has occurred within the FB. |
|
|
B |
ErrorID |
DWORD |
Error code. |
|
|
B |
NodeErrorIDs |
ARRAY OFDWORD |
Array of DWORD. Contains an error code for each element of the Variables array. Length is vendor-specific (MAX_ELEMENTS_MONITORLIST). See Constants of Array Lengths. Shall be the same length than NodeHdlCount. |
|
|
B |
MonitoredItemHdls |
ARRAY OFDWORD |
Array of monitored item handles. Length is vendor-specific (MAX_ELEMENTS_MONITORLIST). See Constants of Array Lengths. Shall be the same length than NodeHdlCount. |
|
|
VAR_IN_OUT |
||||
|
B |
Variables |
ARRAY OFUAMonitoredVariables |
Length is vendor-specific (MAX_ELEMENTS_MONITORLIST). See Constants of Array Lengths. Shall be the same length as NodeHdlCount |
|
|
B |
MonitoringParameter |
ARRAY OFUAMonitoringParameter |
Length is vendor-specific (MAX_ELEMENTS_MONITORLIST). See Constants of Array Lengths. Shall be the same length as NodeHdlCount. |
|
|
B |
ValuesChanged |
ARRAY OFBOOL |
Indicates that the values of the monitored item have been changed. Length is vendor-specific (MAX_ELEMENTS_MONITORLIST). Shall be the same length as NodeHdlCount.See Constants of Array Lengths |
|
|
B |
MinLostValueCount |
ARRAY OFUINT |
Count the minimum lost values if queue size is > 1 – see also UAMonitoredVariables. |
|
|
Notes: VAR_IN_OUT: „Variables” as would provide best type save solution for users: The client firmware is able to map the UA memory layout to the controller layout. The firmware client can receive the type definition from the OPC UA Server.Workaround would be to provide a byte array as “Variables” and the firmware client just provide the blob (UA memory layout – so called “raw data”) into that byte array. A “Variable” could be the name of the variable so the internal firmware can get address, length, data type of variable. |
