Hi,
I am trying to set up a project on pickmaster 3.30 but am having a problem that i cannot resolve. The project has two pick work areas and one place work area. Each pick area has its own tracking card dsqc377B and basler scout gigE camera. Each camera is then distance triggered.
If I run the project I can see the doTrigVis outputs pulsing while the conveyer runs. The problem is that only one camera will respond with a strobe signal and images to pickmaster, even though both are being triggered. Then after about 15secs that camera will stop responding and the other one will start working for about 15secs.. This cycle will then continue indefinetly.
If i disconnect a trigger signal from one of the cameras (either one) then the other one will work fine.
We are using an irb360 robot with irc5 contoller.
Has anybody come across this problem before? I have checked all the wiring and everything look ok. Im using intel dual port adapter with performance driver installed. Pickmaster reports no errors.
Any ideas are more than welcome.
Hi Victor,
If only one camera at a time works it sounds like a network problem. You have two camera, each connected to one of the ports on the dual port adapter, right?
Are the two network ports configured on different subnets? Example:
Port 1 IP Address: 192.168.101.101
Port 1 Subnet: 255.255.255.0
Camera 1 IP Address: 192.168.101.X
Camera 1 Subnet: 255.255.255.0
Port 2 IP Address: 192.168.102.101
Port 2 Subnet: 255.255.255.0
Camera 2 IP Address: 192.168.102.X
Camera 2 Subnet: 255.255.255.0
If you have two network ports on the same subnet (e.g. 192.168.101.x) in the same PC, only one will work.
Also, are you getting any erors/warnings in the PickMaster log?

Hi Fredrik
Thanks for the reply. To answer your question i should elaborate on our setup. Our system actually comprises two robots, each with two pick areas ( total four cameras ) and one place area each (each place area is I/O triggered with predefined positions). We are using one port on the dual port adapter for one camera and the other three cameras are on the second port of the adapter via an advantech switch. I have checked all ip adresses and subnets and all are ok. The two cameras with the problem are both on the same subnet as they are both on the switch. As of yet i have not set up the other two cameras so i dont know if they will have the same problem, but i will check that later today.
Hope this paints a clearer picture. It does look like some sort of network problem but I have checked all the usual suspects ( fixed ip adresses, subnets, no antivirus software installed, windows firewall is switched off ).
Please let me know if you have any other ideas or if you need any more info. Thanks
Just an update on that trigger strobe problem I was having: I was using a sepeate 24V PSU to supply power to the cameras, and the IO card on the robot controller used the 24V supply of the controller. It turns out that the 0V of the two PSU’s were not connected, so strangely one camera’s IO would work ok at any given time, but not more than one.
So by connecting the 0V of the two PSU’s all cameras are now working fine.
