Siemens TIA Portal Course - How to Create your First TIA Portal PLC Application from Scratch
HansRockSolid posted a topic in Siemens
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 -
I'm working on simple structured text program which takes in DWORD values, does some math on them and then outputs in DWORD type. What data type should I be using and how can I make this work? This is one of the lines from the code(everything DWORD) and I get 'operator not supported by DWORD data type' XPos3 := XPos1 + (2*XIncrement);

HI everyone , i will be very glad if anyone helps me to clear the doubt . I am using MX component version of 4 to connect with my CCLINK J61BT11N Board. Is there a way to read group of registers from the CC-LINK . for example, if i want to read from D0 to D5 or write D0 to D5. is there any function in MX component which helps to read the group of registers? I use MItshubi PLC .

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.

Goodmorning a question... I builded a simple monitor of plc. I need to read the data of the Mitsubishi FX3GE PLC. In example I should read: D14 FLOAT 32bit D16 FLOAT 32bit alarms from M100 to M119 and a bit of state M450 How can I do this? The PLC is connected via ethernet and the port il 5002. I'm working with PHP and normally use modbus, opc-ua, etc. But here? Thanks in advance Carlo

Hi, I can’t find an answer to the following and I was advised to ask it here.I’m programming an Omron CJ2M with an MD212 high speed I/O card. I usually do all my programming in Structured text, simply because I like it a lot over ladder or sft.Now, if I want to read the hight speed counter (incremental encoder), I have to make a ladder section and use the PRV instruction to store the present value in a chosen location.The manual says the current PV is stored in A271, but I can’t get a readout there. Apparently the only way to read it is through this instruction.Does anyone know if there is an equivalent to the PRV instruction for Structured text? or another way perhaps? Again, when I check the actual memory adress, there’s no value there withouth the use of the PRV instr.

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.

Hallo. Can someone shed some light on how much memory st takes ? does it use more that traditional ladder? i find that a routine with a couple of thousands of lines uses over 500kB is there any tricks to lower the usage? Or is it just what it is, and buy bigger cpu’s

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 -
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?

Help with ST on M172 please
CoolerGuy posted a topic in Modicon / Telemecanique / Schneider Electric
Hi, I'm new to both structured text and Modicon. I'm having trouble compiling this tiny procedure, meant to scale a number to an integer when the operator changes it. Although I can set the page edit variable to @localparameters.iLTemp_SPt1 with no problems, I can't get this function to compile as either a local or global procedure. What am I doing wrong? -
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

Moving inlet airflow from one damper to another
Rolf_Inge posted a topic in General Topics - The Lounge
Hi. This regards ventilation. A room has two air inlet dampers (pretty much like a big air valve in a ventilation duct). Only one is used at a time to regulate temperature in the room, and the other is then closed. When switching the inlet of air from one damper to another; i have not decided what method to use yet. I consider splitting the regulator output in two and let the one damper ramp down to this value, and the other ramp up. When these values are reached one ramps up to the full regulator output and the other to zero. Not quite sure this is the best solution, and the code is not written yet :) Anyone done anything similar or has suggestions? Cheers! -
Hello: I need to link a lot of variables, pointing to CIO address, like "AT" field, but is a large volume of tags to create, so, I have a chance to assign a memory location to a variable in ST like: my_tag := %100; (trying to assign tag address to CIO 100) ? If not, there is a method to import tags from a Excel ? Thanks.

Hello everyone! Is there possibility to read words e.g. Name of alarm from the csv file or another file and save it in the PLC memory for further processing? It would be the best if the solution will matches to FX5 and IQ-R/F but it can be also for any of them. Thanks for help :)
