  1. I am very knowledgeable with RSLogix5 and RSLogix500, but want to become well-versed with RSLogix5000 advanced algorithms, strategies, and program types—(Ladder, Sequential Function Charts, Function Block Diag, Structured Text), and motion control, such as servo-controllers. . . mostly interested in structured text. I’m also interested in the nuances of RSLogix5000, ControlLogix & CompactLogix regarding design, on-line programming, and off-line programming, etc. Can anyone recommend a course or courses that cover this subject matter? Thanks!
  2. In Part One of the Question: "Can the Omron NJ CPU make the Random Sea?"     There were some fine opinions about that.   This example is what it looks like using Red Lion, Delta Motion RMC75E and LinMot:  https://www.youtube.com/watch?v=SQd6YzBWVvI Recent edit:  The "Big Trycky Omron Question was asked many, many times not shown on this Forum.   I had a very difficult time getting a straight answer from many people at Omron and LinMot.  Probably because they really never tried to do it.  By  the end of THIS thread ( part2 ), Thanks to innoaloe I know that the NJ can generate the position signal, as streaming position data with no time limit, and produce a "randomly" generated model of the ocean's surface.  The "random" part isn't added yet, but, it will work... and the LinMot part isn't added yet .. and it is still unknown if that will work.            
  3. Hi... Trying to keep it simple: Want to make a G5 incremental motor wiggle, CW/CCW in a sine wave motion, Thought this might work:                                                   The variable,  "Angle" is REAL, Phase1 is REAL, AMP1 is LREAL, CSINE is LREAL .. Sysmac doesn't like "Angle" in the FOR statement .. Anyone know why..? Thanks Much, Regards, Michael

  6. GX Developer commands

    Hello everyone! Could someone help me and explain me this block of a ladder diagram I'm working with? I do understand the M800 is always ON contact, for the PLC to not lose the values.  Also I know that the DIV is a division, the FLT is a integer to floating point (thing I don't understand), the DEMUL is a floating point multiplication (thing I also don't understand), the INT is a floating point to 16-bit integer, and the MOV is for moving a value from a data register to an other data register. Help... :(

  8. Monitor alarm block

    Hi all, I would like to monitor the status of my alarm word (MW100) and if any bit turns from 0 to 1 then an alarm signal should be generated, am new to siemens plc and am having a tough time accomplishing this easily. In omrom CX programmer its quite easy to do. Could anyone help me on this using ladder logic, all help will be deeply appreciated.  Regards, Ablex  PS: I'm using Step 7 V5.5
  9. Beckhoff PLC Counter

    Hi everyone, I need some help with my PLC programming. I am currently using a twincat 2 software and a Beckhoff CX 8090. Basically, the gist of my program is to send and receive data and datalog the input data received from the sensors and timestamp the received data for every 1 second. I want to create a boot up counter where it will count the number of times my data logging program has restarted(if it did). This boot up counter serves as a health monitoring check to ensure that my program is running perfectly and thus, not restarting randomly when it shouldn't. I am more familiar with structured text so if you have a solution, kindly post it in structured text form. Your help would be greatly appreciated. Best regards, DeadPool
  10. Hello, I got a new work job to design a cycle tester for a mechanism to make sure will work for at least 5000 cycles open - close. I never made a pls program I start researching few days ago and seams to be very complicate to make it. I have a TM221C16R PLC from Schneider. please help me with some instructions. the cycle tester will have a start pushbutton, stop pushbutton, door open switch, one air cylinder with solenoid to push and pull and a counter. Thank you, Romica

  13. plc ladder switch tricks

    PLC ladder, made to enter an inverted trapezoid, which is to complex, simple post, here is an inverted trapezoid diagram:   The output is made positive trapezoid that briefly after complex.   Writing good ladder, we must follow the above principles, the review does not meet the changes. First, draw the conventional logic circuit diagram, and then facing compile command statement table, table instruction statement written out, can be transformed into a ladder. Simple procedures can be directly edited ladder, more complex, and must be transformed by means of instruction statement tables. Some books say, the ladder of transformation, to follow the "Shen left and right light" principle, with the above said is a meaning. More experience and unwritten rules, but is conducive to the reader to understand, modify. In fact, PLC programming software, as long as the change can succeed, grammatical, are right.  
  14. There are a lot of instructions in function block that are missing the enable input that is present when programming in ladder logic, such as  ADD or MOV.  It seems to be very limiting. The only way around it that I know of is to write your own function block in ladder logic or statement list and use that. I seems rather limiting of a language if it relies on other languages for it to be usable. Does anyone know why the enable bit was left out in many function blocks when it is so useful in ladder logic? Pat
  15. I'm in the process of converting an old Siemens S5 project (with no comments!) to ControlLogix. My first question is in the S5 there is the odd instruction with a '#' in it: - -] [ - - - - (#) - - - - ] [ - - - - -(F00.1) In old logix the # means a file, what does it mean in Siemens speak?   My next question, I have the rockwell document for structured text and also for converting S5 to logx, is there any other resource that would help me understand Siemens structured text?   As I chip away at the project I'll be posting more questions. Thanks in advance for your help.

  17. Mitsubishi PLC

    Dear all,    I need to develop a PLC program for cycle operation. The logic is as follows : When I/p 1 is ON o/p1 should ON, with a time delay o/p2 should ON ,like wise four outputs should ON , if stop button is pressed the output should stop at the current position ,them again if start is pressed it should resume with that output . Can anyone help me with this logic ?? I am using Q03UDE Cpu..Thankyou.
  18. Greetings, We (in the steel industry) have many pumps / motors (large and small).  Generally we use soft-starts,  cross-line starters (E3+) or even Flex drives. There may be several motors in a pool to start where we need only say 2 of 3 to be running at any one time  When it's time to start them, we may need to stagger start them, if one fails, the spare may need to start.  My question to the group is... Are there any philosophies out there (and hopefully pseudo or actual code) as to how to start a subset of motors/pumps within a pool of motors and maintain the configuration running ? I appreciate any and all comments. David 
  19. Hello, I am a student that has been taught ladder logic for three years( on many different plc's ) but, I would like to learn an alternative method is there any way to convert ladder into Function Block or some other type of programming in RS logic 5000 or any other controller? If not can some one explain the basics of Function Block programming.
  20. Hello Dear friends, I have following two problems in RSLogix 5000. I just started working with this software. I am using RSLogix 5000 for my project and I want to use inbuilt drag and drop elements like measuring instruments for example Voltmeter etc. in my ladder diagram. Does it possible or do I need to add some libraries or add ons for that?  I want to plot graph of different properties with respect to time in RSLogix 5000. my question is again the same; what is the way to do it or do I need extra Add ons?  Thank you in advance for your help :) Merry Christmas!!

  23. 3 It has been decided to introduce a Programmable Controller into a manufacturing plant to control a three phase induction motor via an autotransformer in order to reduce high starting currents. It is required to include an alarm circuit which is to give an audible and visual alarm when the motor is overloaded. A momentary actuated Reset push button is to be included in the alarm circuit which will turn off the audible alarm but leave the overload lamp on until the motor overload is reset. Once the motor overload is reset the overload lamp is to be de-activated. The conventional relay circuit diagram for this starter is shown below. A single Stop/Start push button control station is required to initiate the following motor control sequence. a. Motor 1 turns on the instant the start push button is operated; b. Motor 2 turns on 10 seconds after Motor 1 starts; c. Motor 3 turns on 15 seconds after Motor 2 starts; d. Motor 3 turns off after running for six seconds; e. Motor 2 turns off 6 seconds after Motor 3 stops; f. Motor 1 turns off 3 seconds after Motor 2 stops. If the Stop push button is operated, or a thermal overload from any motor is tripped, the whole system will shut down. Motor 1 will start the control sequence again next time the Start push button is pressed.
  24. Hello Everyone, I am new to ladder logic, and trying to understand flow of below attached ladder logic- How does the program flow ? Does PT4601_I in rung 3 waits for rung 2 to complete inorder to consider updated value of PT4601_I or it consider PT4601_I default value and runs simultaneously with rung 2 ? Thank you in advacne
