I'm just starting to learn Ladder Logic Programming. I'm using Allen Bradley RSLogix 5000. I've been tasked with developing a 'Simple' Coffee Machine which operates like so: Toggle Push Button to StartDrop Cup (for 10 seconds)Feed Hot Water (for 10 seconds)If required, Add Milk (for 10 seconds)If required, Add Sugar (for 10 seconds)Procedure Complete - Illuminate Complete Light (for 10 seconds)I have implemented everything except the OPTIONAL add Milk & OPTIONAL add Sugar. Options are: To have a Coffee without either Milk or Sugar.Or have a Coffee with Milk and Not Sugar.Or have a Coffee with Sugar & Not Milk.Or have a Coffee with BOTH Sugar & Milk. I'm considering using Toggle Buttons to select / jump to a Subroutine (choosing the required ingredient make-up). But I'm wondering if there is another way to sequentially go through the procedure? Thanks. http://stackoverflow.com/questions/26930902/ladder-logic-simple-coffee-machine-optional-add-milk-add-sugar?noredirect=1#comment42839041_26930902

Hi all, While upgrading HMI from PanelBuilder32 to FactoryTalk View I encounter a problem using I/O to interface with a PanelView Plus. The communication is defined in RSLogix 5 program as Rack 3 group 2 Size 3/4, range 32-37. PLC communication with the panel is not changed, but buttons in old PanelView using I:34 and I:35 work, in the new PV+ they don't, all bits remain zero. Block transfers Read and Write are all sending data to rack 3 group 2 module 0. While testing I noticed O:32 is used as status bits by the Block Transfers - maybe inputs I:34 and I:35 are also used for somethings similar by a new PanelView Plus? Thanks!

I have a project I am starting and I have to be able to wind a small diameter wire onto a 1/16" shaft, .5 to 1.5" wide and 13 layers at a max speed of 2,000 rpm. Is there anyone who has done something like this and have some sample code? I am gearing 2 Kinetix 350 drives with 2 AB servos.I have a separate tension unit that I have to communicate via RS485. Not to concerned about that. As the coil winds the traverse will move the wire back and forth.

I need help, the control net adapter shown FATL500ad, i need know what means this problem.
