MD4 "Menu system locked" message

Markus Seppänen 2 years ago updated by Gustav Widén (System support) 2 years ago 5


We have a crane control application on MD4-5 and occasionally this message pops up and the whole system is paralyzed and you don't have access to any menu, until restarting the system. 

What is that external system?

It only lets 1 'user' into the menu system. Is someone else connected to the machine with IQANdesign or IQANrun ?

The system has the G11 Bluetooth module but when this message was triggered there wasn't any external device around.

If you forget to click "logout" before disconnecting IQANgo or IQANrun from bluetooth this can happen. Power cycling fixes it.

The MD4 menu system is locked when entering the Adjust menu with IQANrun or IQANgo. 

If connection is interrupted before the IQANrun/IQANgo user leaves the adjust menu, the lock remains.
