plc - Ladder Logic - 'Simple' Coffee Machine - Optional: Add Milk / Add Sugar -

-

I'm just starting learning ladder logic programming I am using Ellen Bradley RSOlogics 5000.

I have been entrusted with the task of developing a 'simple' coffee machine that works like this:

  • Start the push button toggle <
    • / Li> Li> Add sugar (for 10 seconds)
  • Complete the process - Full light illumination (for 10 seconds)

I Everything is implemented, & amp; Add alternative sugar:

Options:

  • To get a coffee without any milk or sugar.
  • Or there is a coffee with milk and not sugar.
  • Or is a coffee with sugar & amp; Do not have milk.
  • Or have a coffee with both sugar & amp; Milk.

I'm thinking of using the Toggle Button to jump over / subtiline (choosing the necessary component make-up). But I am thinking that there is any other way of going progressively during the process?

Thank you. Enter image details here

Here I will do it:

Step 1. Define all actions: - Drop cups, - Hot water feed, - Add milk - Add sugar. For them, make a dedicated routine or addOnInstruction. If you think that this is very simple and not necessary, just think that you have to write a diagnosis for each, and perhaps you can reuse the drop cup in any other project. What happens if you leave the cup, and you are out of the cup, or leaving the device is faulty, and so on?

Step 2. Now that you have separated them, the graph requires everything, even if not.

Step 3. Create the prescription format to insert the parameters to prepare the material - Insert as parameter: Required instrument, numberoffices

Step 4. Make as much dishes as you like . You will never modify the software based on the recipe.

Step 5. Create a recipe management. This will be very useful for all your future projects. This is a time to work.

Similarly, I have made a cocktail bar for my wedding. I told my friends about 20 recipes, and by the end of the day, I got almost 50 in the recipe list.

PS I know that seems very complicated for the given work, but if you get away from your special task and analyze my example, you will feel that the wheel will be used every time Without a re-exploration you can write a program

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
