Point Bridge, which is part of the Base System, enables separate CIMPLICITY systems to exchange point data.

The systems are referred to as:

System Type	Description
Source	Collects the point data.
Destination	Runs the Point Bridge process

	When to use Point Bridge.
	Configuration required for Point Bridge.
	Guidelines for Point Bridge setup.

When to use Point Bridge

Configure points that use the Point Bridge when you:

Have a complex system architecture where users on Viewers need to display points from Servers.

Want to generate alarms on your Server for points on another Server.

Configuration required for Point Bridge

1. Configure a Remote Project for the source system on the destination system.

2. Configure the Point Bridge port.

3. Define a device for the Point Bridge port.

Important: Make sure the Device Name matches the Remote Project name.

4. Define the points you want to retrieve from the source system.

Important: Make sure that the Point Address matches the source project's point name.

Guidelines for Point Bridge Setup

The Point ID on the destination system does not have to match the Point ID on the source system.

The data types and number of elements of the two points have to match.

When the source point changes value, the point value is updated on the local system.

The local point and the associated remote (source) point must have identical:

Point Class,

Data Type, and

Number of Elements.

Reading and writing points are supported.

If a point is configured for WRITE access on both systems, a user on the Point Bridge system can set the value of the Point Bridge point.

The point on the source system is then updated.

Dynamic configuration of Point Bridge points is also supported.

Points configured incorrectly will remain in an unavailable state.

The Point Bridge Device Communications process will generate error messages regarding configuration errors. These can be found in the project's Status Log and the PB.ERR file.

Point Bridge Point configuration specifications

Point Bridge Points require the following entries in the device Point Properties dialog box on the destination server.

1. Create a device point on the destination server.

The name does not need to match the Point ID on the source system, but it can if desired.

2. Select the General tab in the Point Properties dialog box.

3. Specify if the Point Bridge process can set the value of a point on a source system.

For the Read only check box.

Check	The point can only be read on the destination server.
Clear	The point is read/write on the destination server. A user on the Point Bridge system can set the value of the Point Bridge point. The point on the source system is then updated. Important: Write access is only valid if it is configured for the point on the Point Bridge system and on the source system.

4. Select the Device tab in the Point Properties dialog box.

5. Make Point Bridge specifications as follows.

		Option	Description
Up	A	Device ID	Node name of the source system where the Point Translation process is running.
	B	Address	Point ID of the point on the source system.
	C	Update Criteria	Only Unsolicited updates are supported.
	D	Diagnostic Data	Diagnostic points are not available for the Point Bridge. Clear the Diagnostic Data checkbox.
	E	Poll After Set	Poll After Set is not supported by Point Bridge. Clear the Poll After Set check box.
