Step 3.1. Set General Point Properties

When you configure a new point in the Point Properties dialog box, entries on the General tab that apply particularly to the OPC configuration include the following.

You may configure points for:

Read only (check Read only) or

Read/Write (clear Read only) access.

When you select the Data Type for the point, the OPC Server, with which the OPC Client communicates, determines the validity of that type for the selected point.

If the point is rejected by the OPC Server because the requested type is not valid:

CIMPLICITY will declare the point as invalid.

The OPC Client will log a message to the Status Log indicating that the point was rejected because the point type was invalid.

Note: In some OPC Servers, points that are configured within the OPC Server may be any of several allowed point types.

Check your OPC Server documentation! The more familiar you are with your particular OPC Server, the easier it will be to configure points successfully.
