Hi Everyone, I am supporting a system which runs on a SLC 500 (1747-L532). A fault has developed whereby the output state of some digital outputs do not change within the ladder logic. Basically, on a rung, an XIO controls an OTE. When the XIO is high the OTE should be also high, however the OTE is not changing state. The OTE is only used on this 1 rung within the program and the routine is being scanned. I have trended the XIO bit to confirm no oscillation and at a trend refresh rate I cannot see any change of state. The XIO is controlled via a compare instruction which is stable. I have plugged out the comms to the machine HMI to confirm nothing is being written from the HMI that may be causing the issue. I have also tried another processor from spares but issue remains.  Is there something very simple I could be missing here? All suggestions appreciated. 

Hi Joe E,   Thanks for the reply. This is worth exploring, however the box sizes, qty of boxes, box orientation are different for each of the 19 formats so tedious to say the least. It is only a 2D representation of the top layer that will be displayed. I am beginning to regret that it was I who suggested this option to the customer!!!

Hi BobLfoot,   I did consider this but I don't like creating screens with a lot of hidden objects overlayed on them. For the next person who opens the screen in the development file its difficult to work with the screen when ther are multiple layers of shapes all on the screen.

Hi all,   I have a palletizing cell with two pallets each side of a palletizing robot. I have an FTView ME (ver 11) application running on a panelview plus HMI.   There are 19 different recipes on the machine each with a different pallet configuration. There are on average 5 different place positions on each layer of the pallet.   On the HMI, I am attempting to show a graphical representation of the amount of boxes currently  loaded on each layer. From our solidWorks software we have saved an image of each of the 5 place positions for each recipe. By this I mean for example on Recipe A, I have separate images of the pallet with 2 boxes shown on it, 4 boxes shown on it, 6 boxes shown on it, 8 boxes shown on it, 10 boxes shown on it.   So for each recipe there are 5 images  (times 19 recipes = 95 images) ( times 2 pallets shown on display = 190 images)   Trying to place all these images on the display and control their visibility via recipe type and boxes placed tag works in theory. However to load the display takes a very long time, understandably.   Is there another sleeker way this can be achieved without embedding the images into the display, like load a specific image when a certain tag value is high.   Thanks in advance
