Passing Analog Data Between Multiple I/A Series UNC-520s and DMS Panels

[Product_Support]

Issue

How to share or broadcast analog values between multiple I/A Series UNC-520 controllers using a DMS-3500 panel.

Product Line

TAC IA Series

Environment

• I/A series UNC-520
• DMS-3500

Cause

The system requires analog values to be broadcast globally across multiple panels. Direct linking of points does not work because the analog input needs conversion from floatStatus to floatPriority for proper handling.

Resolution

1. Create Dummy AP Point

   • On each DMS panel receiving a global analog value, create a dummy AP point (UC AP).
   • Assign a name and set AP type to 07.

2. Configure UNC

   • Learn the new point at the UNC.
   • Select PVALU:WRITE, then click Add and Create.
   • Two objects will appear: AO and DmsGenericAO.

3. Insert Math Object

   • Add a Math object in the workspace.
   • Link pOut of Math object to pIn of AO.
   • This converts the AI from floatStatus to floatPriority.

4. Broadcast Setup

   • Link sinA of the Math object to the analog point in the DMS panel that will be broadcast globally.

     

   • Edit the Broadcast Channel and assign the correct GLOBAL number.

5. Address Book Configuration

   • For each UNC station, add all peer IP addresses to the AddressBook under PEER setup.

6. MicroSmart Integration

   • For any MicroSmart controller, create an LP point and link it to the DMS AP point.
   • The DMS AP acts as the input for the MicroSmart LP point.
