  1. Did you always wanted to get started with Siemens TIA Portal programming, but you were never sure where to start or how to get the best performance out of the platform? Eager to upgrade your TIA skillset from an instructor with over 10 years of TIA experience in the field?   -> Then this course might be just for you! My course "Siemens TIA Portal - PLC Programming Basics" will take you through the steps of creating your very first TIA application - from structuring (very important!) and programming your application, to downloading and troubleshooting your application online.  The course is based on video lectures and is around 2.5 hours long, and consists of 40 lectures divided over 6 main chapters. The enrolment fee is offered at a huge discount at the moment, so take action while it lasts! Take me to the TIA Portal course, I´d like to check it out...   Thank you, and I hope to see you inside the course! Hans
  2. Control Panel

    Is it possible to view the values / states of all inputs, outputs and workbits (e.g. 64.00 through 64.15 on Omron CQM1 PLC) on a single screen or control panel within CX-Programmer software?  I'm trying to troubleshoot some ladder logic that I wrote and need to know the values of 5 or 6 inputs/outputs/workbits simultaneously.  Having to scroll up and down through my ladder logic repeatedly does not work well with code that changes state every 5-10 seconds or so. Any help is welcome.
  3. Q03UDVCPU

    I am new with PLC's and I am learning how to work with GX Works 2. I have two questions, 1st Question: Using a Q series PLC (Q03UDVCPU) Is it possible to convert the language of a project from ladder logic to structured text? 2nd Question: If I read a project from a PLC why is it always ladder logic? Is there any way to read out structured text?
  4. Hi I'm looking for Ladder Logic code that I could use for a plastic injection molding machine.  I am willing to purchase and/or modify existing code to meet our specifications.  We have lost the Ladder Logic out of the TI/Siemens Controller on our Newbury 100 Plastic Machine so we're looking at replacing both the PLC and the HMI interface with an Automation Direct Controller.  We have the HMI Basic Code for the Newbury but not the ladder.  I've pasted the manual below for our machine.  Any assistance would be much appreicated.  The manual was too large for me to post but I've posted a document with information about how we intend to upgrade which has a little information about the machine also.

  5. Hey there, I have an "Italian safe CNG dispenser pm head". I googled about it and found that It is a plc board. So I searched how to program it. Then found it use ladder programming language. Now there are no tutorial or documentation about its programming. But I want to repair my damaged plc board. If I goto any technician they will charge a huge amount of money. So I thought I will repair it by my self. So need help about the software name its use and how can I program it.  If any of you guys know about it please provide me your precious knowledge. Use this printerest link for see my pm head(plc board) https://i.pinimg.com/564x/0e/d6/6c/0ed66cb9a1065ab10a07e0b9aadc6f0d.jpg   Thank you (TIA) Masud karim

    Hello everyone, I want to ask,, Does address mapping use this concept to do "remote i / o station" can be done? following the network parameter settings for CCLink and I tried to program with this ladder, is that correct?  
  7. GX Work2 Comments in Arrays

    I am very new to the Mitsubishi PLC world (I have a lot of experience with A/B and Omron though).  I am having an issue trying to assign comments to an array of Globally scoped bits - I am also using Structured Ladder - NOT simple ladder.  Is it possible to do this?  I have contacted there tech support group and they were of little help.  I don't care if I update the label comment or the device comment, I just want to assign a simple comment that can be displayed (i.e. I am using this for step sequences).   Any help would be greatly appreciated!  
  8. ladder program

    Hello everyone, I want to know why the Y172 coil is ON / logic 1? whereas contact SM1 is worth OFF / logic 0? can anyone explain it to me ?
  9. Hi everybody! I am an experienced electrical/electronics technician with 6 years of maintenance experience, and my boss at the factory recently suggested that I should start learning PLCs so I can take over the automation maintenance all by my own team. I have a lot of time to prepare for this position. What is the optimal way to start? We are working with OMRON equipment. I found some courses that look interesting, so my training plan is: 1 finish the free courses - the ones from Omron Learning website - the one from LinkedIn learning "Learning PLC Ladder Logic Course by: Zahraa Khalil" 2 finish the payed courses on UDEMY - Learn 5 PLCs in a Day-AB, Siemens, Schneider, Omron & Delta - PLC Programming From Scratch (PLC I) -  Practical PLC Programming (PLC II) -  Process Visualization with HMI / SCADA (PLC III) -  Advanced Programming Paradigms (PLC IV) - From Wire to PLC , A Bootcamp In Industrial Automation -  Factory Automation using PLC Logics   That being said, can you suggest me more courses / textbooks / training programs? BTW your forum has been a good source of information for the last few days that I have took to research the topic, so I want to thank you all for providing all of this information. God bless you all!    
  10. Bits on Contactor

    I use ladder logic in its most simple form. In ladder logic on the left, I have contacts(ANDs and ORs configuration). They are either switches, logic results of functions or switches, or canned strobing On the right, I have all types of functions, timers, keeps, counters, etc. As a simple example, I have a canned 1 second strobe feeding a counter. I can use the counter as a contact to close when it reaches zero. Does all of the" business" have to happen on the right? For example, the left side of the IF/(contact) statement can I put something like a bit comparison on the left? Something like... Counter, Bit# Or do I have to use a bit comparison on the right and its binary result as a contact and put it on the left?     Thanks    
  11. How to watch the value in decimal directly in the ladder page ?  Default Hexadecimal The only way I can do it is in Watch Tab and I/O map per example Thank you
  12. I am new to PlC programming . Plz can anyone guide me for ladder programming for FX5U -4LC Temperature controller with autotune parameters . Plus i want to use a PT-100 for the same . Plz help me out.
  13. Hi..  someone please help me.. i'm working in omron CS1H-H CPU67 PLC. My struggle is I/O in one particular rung is not getting updated.  Note: the rung is consist of a P_On flag followed by a FB ; all I/O to the FB were correctly assigned. but the inputs inside the FB instance are not getting updated so that the output not updated. can anyone please help me....????   sorry for my poor english... thanks in advance.
  14. Hi there! I have a question with AB PLC. My problem:  I have some raw data...distance for example.When the machine starts,the sensor begins to send the information with the distance values. When data is received it is moved into an array. After the first 5 values the program calculates an average and the result is moved into another array.Currently after receiving the fifth value,thus filling the first array,making the calculation and sending the average to the other array,the program empties the entire first array instead of just always discarding the oldest value of the five,and recalculating the average with the newly arrived value every time. I tried to made this with ladder diagram using an an fifo load and unload but isnt working. Please help me if anybody can. Thank You.
  15. Ladder Display Format Change

    My program has the option Tool | Options | Program Editor | Ladder | Ladder Diagram Display Format set to 11 Contacts.  Are there any repercussions to changing this on an existing program?  I would like to spread it out to the 17 Contact setting.

  17. Structured Ladder

    Need Help! I uploaded structured ladder program into FX3S PLC. But When I try to read it from PLC it says the program cannot be opened. 
  18. Ok, so I have 22 bits that I need to monitor the status of; all in separate words. Each change of state (on each bit) I need to trigger a timer and have the timer done to completion. I'd like to have the timer reset if a bit changes state during timing. I'd like to keep it to one timer. I'd like to keep things as simple as possible so the less rungs / branches the better. Any help?
  19. Hi Everyone, I'm working on my first PLC program and I have gotten my hands on some ladder logic I'm trying to duplicate. I'm using SoMachine 4.1 and have started a new Ladder Logic diagram POU. I'm curious on how do I create internal contacts. EXAMPLE: 24v--------l START BUTTON l----------------( COIL A)----- --------------l COIL A CONTACT 1; attached to a real output, solenoid valvel-------------l COIL A INTERNAL CONTACT TO CLOSE l---------------- Are there standards for numbering and labeling? I'm seeing L and U inside coil contacts. Does this have an underlying meaning according to standard? Is there a RTO function inside SoMachine 4.1    
  20. Hi everyone, I'm a newbie in the ladder logic programming languages. For my thesis project I've to develop a scenario but I'm stuck with the creation of a socket connection from the Modicon M340 PLC to a server for transfer continuous data given from sensors or similar. Does anyone have a sample program that could have such a functionality so that I can change it based on my needs? Thanks in advice for any further reply!
  21. Hello, I am currently working on programming my first sortation system.  Attached is a blue print of the in feed conveyors and their loadout lines.  As boxes merge together they will be scanned by the barcode scanner.  From there we will be told which lane each box must go down, from the WCS.   My question is, without encoders, what would be the best way to control this system? Counting the packages as they pass through the photoeye? Or setting timers?   Thanks, James Sorting Conveyor Layout.pdf

  23. I hate to start a new topic on such an old processor but I forced to keep this thing working until I can upgrade it.  We are having funny issues with outputs.  At first they were on a PLC5/60.  We suspected a bad processor so we changed to a PLC5/40 we had in our tool crib and the problem didn't go away.  Some of our outputs in the ladder are being evaluated to true but not turning on.  We can force the output on and it will come on and when we remove the force it will turn back off.  I've never seen this problem before on any processor.  All the logic leading up to the output is true but the output is not turning on and is there not green. I've already checked all the obvious causes.  The instruction is an OTE.  The output is not duplicated somewhere else in the logic that is turning it off.  The ladder file is being scanned.  I replaced the output with a B3 bit and on the next line had the B3 bit turn on the ouput.  The B3 output bit turned on but the output did not.  This output is on a remote I/O rack and other outputs on that rack are working. Any ideas would be greatly appreciated.
