The purpose of this OPC V3 method is to provide an extremely easy way for simple applications to obtain OPC data. Programmers should be aware that in most servers, the design of the Group based OPC interfaces will provide much better performance than this method. In terms of performance, the user of this method should assume that it will behave as if he were to create a group, add the items, perform a single read or write and then delete the group.
Overload List
| Overload | Description |
|---|---|
| Read(String[],Int32) | OPCDA V3. Reads a group of items with all the same maxAge The purpose of this OPC V3 method is to provide an extremely easy way for simple applications to obtain OPC data. Programmers should be aware that in most servers, the design of the Group based OPC interfaces will provide much better performance than this method. In terms of performance, the user of this method should assume that it will behave as if he were to create a group, add the items, perform a single read or write and then delete the group. |
| Read(String[],Int32[]) | OPCD V3. Reads a group of items with individual maxAges The purpose of this OPC V3 method is to provide an extremely easy way for simple applications to obtain OPC data. Programmers should be aware that in most servers, the design of the Group based OPC interfaces will provide much better performance than this method. In terms of performance, the user of this method should assume that it will behave as if he were to create a group, add the items, perform a single read or write and then delete the group. |
