Error 74 Using Kuka Robotics Library

tocreemer — Wed, 24 Jan 2018 09:01:34 GMT

I'm currently troubleshooting a labview setup using the Kuka Robotics Library. When I run my program it results in error 74 from the MxAutomation Client. Since this VI is locked I cannot drill into the code to see what is throwing the error. Does anyone have experience with this error? Any help would be appreciated.

Thanks in advance for any support.

Hello, tocreemer

We have already discussed this issue over e-mail, but I post the solution here, so it will be available for forum users as well.

Symthoms:

1) Error 74 is returned by VI "mxAutomation cleint 2.1"

2) UDP communication with KUKA controller is working (example KRL-ex1-communication_check-ni-udp.vi reports OK)

Reason: KRmsgNET (KUKA error/information status sender service) is configured to send messages to same udp port (1336/1337) as mxAutomation uses for communication. This causes fatal errors during message parsing.

Remedy: Change KRmsgNET settings (on KUKA smartHMI). To do so,

1) Log in as Administrator or Expert.

2) Open Menu -> Start-Up -> Service -> KRmsgNET

3) Change "Send / Port number" to NOT 1336/1337. Usually port 9050 is used. To disable KRmsgNET sender completely, set IP Adress and Port Number to all zeros.

3) Change "Receive / Port Number" to NOT 1336/1337. To disable KRmsgNET receiver, set Port Number to zero.

4) Maybe a controller restart is needed after that.

Regards!
