Hi there! I recently discovered this forum and I find it pretty useful for sharing and learning about PLCs. The thing is I'm trying to make a Stack using the SSET(630) instruction in a CJ2M PLC. Reading Omron's W340 manual I saw that PLC memory address for the different stack channels is represented as "00010000" to "0001000F". So, in order to set the last stack word address as well as the pointer's address, how do you know those values? Or am I just misunderstanding something? Thanks in advance! Edit: Solved, the definition of the stack was wrong!

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.

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?

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.

How to konw what type of ladder programming language is support by the plc compnay
forbidden_masud posted a topic in Other PLCs
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- 1 reply

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!

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!

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

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.

So I did this simple Function Block, pretty simple, and yet it keeps giving me this error, after a bunch of failed combinations the error persists, without telling me whats wrong. And therefore won't even allow me to download the program to the PLC (CJ2M CPU31) or even simulate. I heard it's a simple thing to fix but I really dont know how to, since I'm quite new to this. Here's the function block itself in the picture and the programming inside it, although since it gives me no errors, i don't think that would be the problem

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.

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?

"Ladder Logic" internal contact set-up
MikeOrsini87 posted a topic in Modicon / Telemecanique / Schneider Electric
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- 1 reply

Ladder Logic socket communication
Br4zzor posted a topic in Modicon / Telemecanique / Schneider Electric
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!- 3 replies

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
