Issue
How to set up a Operator Panel to only see the TAC Xenta controller it is plugged into
Product line
EcoStruxure Building Operation
Environment
TAC Xenta Operator Panel firmware 3.7
TAC Xenta Programmable controller 3.85 or higher
Cause
When the Operator Panel is plugged into a TAC Xenta programmable controller the whole network of TAC Xenta controllers are listed.
Resolution
This option and the requirements are described in this TPA
To enable the option in the TAC Xenta:
How to enable this in the TAC Xenta: Edit the application and create a Public PVI-block with the name XENTASYSREG and set this block’s initial value to 8. If you have multiple TAC Xenta OP panels in the network, each one connected to a specific TAC Xenta Controller, it will be required to create this special PVI block in every one of these TAC Xenta Controller’s application code.
To enable the option in the OP Panel:
1. Open the TAC Xenta OP local service menu, by pressing and holding the “escape” and “enter” buttons for a few seconds.
2. Enter the bottom command: “11 OP connects to”.
3. Enter this sub-command, and then type in, using “+” or “-“, the specific TAC Xenta controller’s subnet and node address you want this OP to be “locked” to. The TAC Xenta controller subnet and node addresses can easily be found in TAC Vista Workstation; select “properties” for the TAC Xenta controller and the subnet/node address will be displayed.
Observe that when you select, in the OP panel’s new menu, the node number and press enter the TAC Xenta OP will restart and seek for this now selected TAC Xenta controller. Note that it is still possible to access this specific TAC Xenta controller from another TAC Xenta OP in the network if that TAC Xenta OP is of a version prior to 3.70 or this new “lock-function” is not enabled in that TAC Xenta OP. However doing this, you will only here also “see the local TAC Xenta controller”. In this case you will be able to exit this TAC Xenta controller again by pressing “escape”. While in the locked TAC Xenta OP you will not be able to exit from the TAC Xenta controller it is locked to.
