Problem: The OPC client does not provide a means to configure access paths, making it difficult to correctly specify the data acquisition options for the items. |
Solution: The server provides a global parameter for configuring an escape character to allow users to append communication options to the end of an Item ID to accommodate clients that do not support access paths.
Perform the following steps.
Create a string value named ItemIDEscapeCharacter in:
HKEY_CLASSES_ROOT\CLSID\{024C7FFC-9CC3-476f-867A-BC3CAD79F4FE}\Options
To create a new value, select the Options key, and then choose New String Value from the Edit menu.
Set the value of ItemIDEscapeCharacter to a single character, such as "|" (pipe).
To edit the value, select the entry and choose Modify from the Edit menu.
Shut down the server and restart it to have the change take effect.
Configure the ItemIDEscapeCharacter Item ID in the OPC client with the access path appended to the end with the configured escape character (e.g., ITEMID|ACCESSPATH).
