Regarts excuse i am using the ethetnet communication (LAN1) in a hmi dop w 157B , and the option for declare the 32 recipe's address (D100 in the video) isnt be any more, i have to declare with a binary from my plc (allen bradley) could you help me?
I appreciate the attention. Sorry, I think I have a lot of doubts and maybe it's not possible to solve them here. I'm looking for a way to make recipes that are dynamic, not fixed ... Recipes where at every step I would command a routine of my PLC and they would be executed sequentially according to the need of my process. Recipes that save a sequence of routines and their variables. For example a cake maker: Cake A: First place (x) kgs of flour, then 4 eggs, then beat the dough, then heat (X) degrees celsius, then place the cover, etc ... And for each type of cake would be a different recipe with different variables too ... I am researching how to do this ... because the steps of the process I have already developed in the PLC, now I only need to make the hmi execute them sequentially according to the selection of each recipe . Thank you.
For each product the variables change (kg, liters, temperature, time) and the execution sequence of the routines also ... for example; in the cake I put the flour first, then the eggs, then the sugar ... in the B Cake I put water first, then eggs, then flour ... Some products have a larger sequence of routines and smaller ones ... The routines are ready, I do not know how to enable the operator to create and save their recipes, so each time you select a product and start a program, the machine performs the steps as determined in the recipe.
mm.. Dear Enrico if you are using Delta PLC in that instead of ladder logic there is one more language called SFC(Sequential Function Chart). In this language you can write programs as steps by defining ACTIONS and TRANSITIONS. I guess to implement your logic this would be best. SFC might be little difficult in beginning but will suit your application. Now for recipe i guess you have to create two separate recipe. "Material Recipe" with details of each product , its volume and unit. "Process recipe" table which define the order of process sequence( mixing, heating etc) when user select a product you have to call two of these recipes. Back in PLC program you will define your each separate process in separate "ACTIONS" under SFC program. based on the order defined in the "Process Recipe", particular "ACTION" can be invoked when ever required. In Delta HMI there is Ehanced Recipe in which you can also define multiple datatypes in single row . Please check my video of Enchanced Recipe ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EBO6aZIuK8I.html for that. When u try start with simple recipe (max 4 steps and 4 products or something and then try to implement the logic). writing program with all of the parameters in the beginning will be cumbersome for debugging.. Hope atleast some this tips would help you. Thanks again for responding and follow the channel for further more updates. Keep n touch
