OPC DA Source Service Properties

To add an OPC DA source service, use the OPC DA source service type.

You can configure the following properties for the File source service type:

Entity Name: Name of the OPC DA source service. Maximum length is 32 characters.
Description: Description of the OPC DA source service. Maximum length is 256 characters.
Host Name: Host name of the machine where OPC server is installed or configured.
Domain: Domain name of the machine where OPC server is installed or configured.
User Name: User name to connect to the machine where the OPC server is installed or configured.
Password: Password to connect to the machine where the OPC server is installed or configured.
OPC Server: You can specify one of the following identifiers for the OPC DA server:

Programmatic Identifier (ProgID).

Class Identifier (CLSID).
Programmatic Identifier (ProgID): The ProgID of the OPC DA server. Specify this ID if you select
Programmatic Identifier (ProgID)
in
OPC Server Details
.
Class Identifier (CLSID): The CLSID of the COM class object of the OPC DA server. Specify this ID if you select
Class Identifier (CLSID)
in
OPC Server Details
.
Tag List Specified As: Format in which the list of tags is specified. Select one of the following formats:
Text
File
List of Tags: List of tags to be read by the OPC client, specified as a JSON array.
Path for Tags File: File containing list of tags to be read by the OPC client, specified as JSON array.
Polling Interval (milliseconds): Interval at which the source service reads tags from the OPC DA server. Specify a value that is less than the rate at which the OPC DA server publishes data. Though this avoids data loss, it could result it in data duplication.
Maximum Event Size: Maximum length of data that the source service can read at a time, in bytes. Default is 8192. Minimum value is 1. Maximum value is 51200.
Retry on Failure: Indicates that the source service should try to open or read from the source if the operation fails the first time.
Number of Retries: Time in milliseconds between successive retries. Specify a value of more than 200 milliseconds.
Delay between Retries: Time in milliseconds between successive retries.
Persist Data: Persist the data from the source locally so that the source service can continue to process data even if the target is not available.
Persistence Options: You can configure the following persistence options:
batchSizeInBytes
. The batch size of the events in bytes after which the data is written to the persistent store. Specify a value of 0 if you want to write the data to the persistent store immediately. Default is 262144 bytes.
flushInterval
. The interval in milliseconds after which the source services writes data to the persistent store. Default is 5000 milliseconds.
maxDataFiles
. The maximum number of data files that the source service can keep in the persistent store. After the number of files exceed this number, a rollover occurs. Default is 10.
maxDataFileSize
. The maximum size of each data file in bytes. When the file reaches the specified size, a file rollover occurs. Default is 1073741824.
maxQueueSizeInBytes
. The maximum size of data that is unsent or has not received acknowledgment in bytes that can be stored in the persistent store. If the specified size is exceeded, the source service does not read data from the source. If you specify a value of 0, the unsent data can be as much as the value of
maxDataFiles
times
maxDataFileSize
. Default is unlimited size.
Statistics: You can monitor the following statistics:
Bytes Sent. The number of bytes sent by the source service.
Events Sent. The number of events sent by the source service.
Events to be Sent. The number of events that the source service is yet to send.
Events not Delivered. Number of events that the source service did not deliver.
Send Rate (Per Sec.). The number of bytes sent every second.
OPC DA Events Read. The number of events read by the source service
