Issue
The Xenta application may crash or become corrupted, resulting in one or more of the following symptoms:
- Controller not online in Vista Workstation
- I/O modules fail to associate with the Master
- Controller does not accept downloads via System Plug-in
Product Line
TAC Vista
Environment
Xenta version 3.61 or higher, Xenta 280 (281, 282, 283), Xenta 300 (301, 302), Xenta 401
Cause
Crashes may occur during interrupted downloads or due to other system anomalies.
Resolution
Step 1: Power Cycle
- First, try cycling power to the controller to see if the issue resolves.
Step 2: Forced Application Clear (if power cycle fails)
If the controller still refuses to accept downloads from Vista or Menta:
-
Create a Reset Dongle:
- Use an old Cat5 network cable.
- Cut off one end, leaving 4–6 inches of cable.
- Short-circuit the specific pins required for reset (refer to pinout diagram or manufacturer instructions).
-
Perform the Reset:
- Power off the controller or remove it from the base plate.
- Insert the manufactured RJ45 jack into the RS-232 port.
- Power on the controller or reinsert it into the base plate.
- This will trigger a forced Clear Application.
- Remove the RJ45 jack.
- Cycle power again to complete a fresh boot-up.
