I/O Triggered Vision [PickMaster 3]

PickMaster
1

I have just set up an I/O triggered vision camera for the pick position sorce. The I/O trigger is set high (24v) every 500ms for a period of 50mS to capture a new image from the camera and the set up works. But every time the I/O trigger is set high the pickmaster log has the following 3 warnings 4318,12308 and 12309.I cannot see what or were I am going wrong as the frame rate does not seem very high. Has anyone got any ideas please.:smile:

Hello Mark,

As you stated that you only trigger the system twice every second but you still receive warnings that a camera is triggered too fast it makes me believe that you have too CPU-intensive vision models. Are you using a complex patmax model? It might also be caused by glitches or noise on the trigger wire connected to the camera (which would cause the camera to try to take more pictures than what the system is capable of).

When I look at the images in the detailed vision window the process time indicated is 0.4mS, the model is a blob model. When this line was first installed the camera was triggered on distance, this had no problems, only now I have changed to I/O triggered camera do I see the warnings in pickmaster, so I suspect it is not a noise issue.Just a little more detail this is 2 flexpickers in series using a 8100D CDC50 digital camera.The wiring is as follows

Camera Strobe + to +24v

Camera Strobe - to terminal 9 of DSQC377

Camera Trigger + to both robot controllers termianl 5 on X1 via diodes

Camera Trigger - to 0v

Camera I/O triggrer to both robot controllers terminal 1 on X3

Hope this wiring is all correct

Hello Mark,

I assume that the camera strobe - signal is connected to terminal 9 on the DSQC377 boards in both robots (in parallell).

Please verify that the I/O pulse from the photo eye is clean. Another way around it is to set filter active for the position generator signal to perhaps 50ms to ensure that there is no noice.

Still, if this persists to be a problem. Please provide us with the system number of both controllers (34-xxxxx).

BR,

Erik

Thanks for the last reply, the 50mS filter on the digital input worked. It was originally set to 0mS.

Hello!

Where can I find this filter?

This is a robot configuration and may be changed from either RSO or the FlexPendant by changing the system parameters. I do not know exactly (out of my head) where you can change this but it is related to the setup of the I/O system.

Please refer to the RSO documentation or contact SEROP Product Support.
