We have a CRX-10ia  and RoboDK 5.6.7 and are experiencing some communication problems. It takes a few tries to connect initially then, while running, the Robo DK "Stop" button does not stop a move, so we have to stop motion via the teach pendant. When this happens the connection gets messed up and we have to fully disconnect and reconnect to recover.

That is kind of the beginning of our problems connecting. When we attempt to reconnect we have to follow the process below a few times and eventually the connection is made.

The process to get the robot to connect is:

• RoboDK: double click disconnect
  
• Fanuc teach pendant: Reset alarms
  
• Fanuc teach pendant: stop and restart RDK_S3
  
• RoboDK: click connect
  
• At this point RoboDK usually throws one of the errors below, we don't know how to predict what error we will get:
  

Code:

Sending command...
Disconnected
Sending command...
Trying connection 192.168.1.156:2000...
Unexpected error: 0
Using V2 Real
Version -10001 (type -10001)
Ready
Unexpected error: 0

We repeat this process a few times and eventually, the connection is made. Once we are connected we can run without issues, as long as we do not stop a move through the teach pendant.

This forum post seems to be related to the same issue. We get the same INTP-311 fault on the controller which says "Uninitialized Data."  from line 507 in RDK_S3.

Any help will be appreciated. Thanks!

You may be using an older version of the driver files on the Fanuc robot controller. I recommend you to update RoboDK to the latest version:

And use the latest version of the driver for Fanuc controllers:
