Issue
When a TAC Xenta Operator Panel (OP) is connected to a TAC Xenta programmable controller, it displays the entire network of TAC Xenta controllers. In some cases, it's desirable to restrict the OP to only view the local controller it is directly connected to.
Product line
TAC Vista
Environment
- TAC Xenta Operator Panel firmware 3.7
- TAC Xenta Programmable controller 3.85 or higher
Cause
By default, the TAC Xenta OP scans and displays all TAC Xenta controllers on the network. This behavior may not be suitable for installations where each OP should only interact with its directly connected controller.
Resolution
To restrict a TAC Xenta OP to only view its local controller, follow these steps:
1. Configure the TAC Xenta Controller
- Edit the application in the TAC Xenta controller.
- Create a Public PVI block named:
XENTASYSREG - Set the initial value of this block to:
8
Note: If multiple OP panels are connected to different TAC Xenta controllers on the same network, you must create this PVI block in each respective controller's application code.
2. Configure the TAC Xenta Operator Panel
-
Access the local service menu on the OP panel:
- Press and hold the “Escape” and “Enter” buttons simultaneously for a few seconds.
-
Navigate to the command:
11 OP connects to -
Enter this menu and use the “+” or “–” buttons to select the subnet and node address of the specific TAC Xenta controller to which the OP should be locked.
- You can find the subnet and node address in TAC Vista Workstation:
- Right-click the desired TAC Xenta controller.
- Select Properties to view the address.
- You can find the subnet and node address in TAC Vista Workstation:
-
After selecting the correct node, press Enter.
- The OP panel will restart and connect exclusively to the selected controller.
Additional Notes
- If another OP panel (with firmware prior to version 3.70) connects to the same network, it may still access other controllers unless the lock function is also configured on that panel.
- Once locked, the OP panel will not allow navigation away from the assigned controller.
- To exit the locked controller view, press “Escape” (only possible if the lock function is not enabled or the firmware is older than 3.70).
