I am using two Banner WLS27PXRGBW1130DSKQ in our system. I am having issues with running both lights at the same time. I can write to both of them but cannot get them to start flashing at the same time in sync. I understand that internal clocks will allow them to be different after some time but I cannot get them to be the same right now. I am using a B&R Automation X20DS438a master controller and each light is on channel 1 and 2 respectively and I am using Flatstream to write to the devices as each device has 32 bytes of data writing to it. Let me know I am able to do to fix this with the equipment I have available now. I also understand that an IO-LINK hub might be needed to make this work but I am on a tight deadline and would rather not wait for more hardware in order for this to work. I am happy to provide any more information needed. Thank you!
This is being handled by the local support team. We will update when there is a solution.
The issue was using a slow task class for the AsFltGen library. Since the task class must be run to update/send the next set of flat stream iomapping, in a slow task class the process took long enough to visibly desync the stack lights.
Moving the task class from a 100ms to a 3.2ms (PLK/X2X at 1.6ms) removed enough delay that the lights should appear to the human eye as in-sequence.
