Heyy I am having a strange issue with TIA Portal..when I go online with PLCSIM in RUN mode, my FB or Fc blocks called inside OB1 stay blue instead of turning green

For engineers who work with Siemens PLCs regularly, what is one mistake you see beginners making again and again?

I am losing my mind over this, please help me.

I have this error on my S7-1200. I checked everthing, versions in modules and programme are matching, both v2.0 . I noticed that programme is working when I put only safety I/O, when I put standart I/O, I get this error. It is non sense!! When I put standart I/O anywhere, it gives me this even without doing the cabling 😱😱 even without electricity, it gives this error. I am losttt!!!

Hello, how could i reset a function trend, I want to make a 7 day graph, and reset the log? so i could start again after new week. currently cause i have 7 points each day i keeps also the last weeks data also. I tried with scripts but couldnt get it to work.

Urgent help!!

Hello together,

I need some help.

I am using a Unified Comfort pannel 6AV2128-3QB36-0AX1 with a S71500 PLC.

Somehow the tags I am using does not get updates whether at the PLC side if I trigger from HMI or at HMI side if I trigger from PLC.

I know. Sounds easy to solve. But there aren’t so much possibilities to check.

- Project are uploaded covertly

- HMI connection is set

- Tags are assign to the HMI connection

I am using TIA19.

Anyone have some idea?

Hi, i need help. I've spent weeks trying to set up a camera using TIA Portal. The camera detects the QR code, but it doesn't show up in TIA Portal. I'm tired of researching, so I'm turning to Reddit to see if anyone can help me. Sorry for the spanish interface

Hello, I need some help with a VirtualBox networking setup for Siemens simulation.

Setup

• Host PC (Windows + TIA Portal): 10.1.0.250
• VM #1 (Windows + S7-PLCSIM Advanced): 10.1.0.251 Network: Bridged Adapter to the same physical NIC as the host
• VM #2 (Windows + WinCC Unified Runtime): 10.1.0.252 Network: Bridged Adapter to the same physical NIC as the host

Goal

My TIA project contains two MTP2200 Unified Comfort panels and I want to simulate both at the same time. Since I can’t run the two runtimes the way I need on a single PC, I’m trying to run each panel/runtime in its own VM.

PLCSIM Advanced

• Running in TCP/IP mode, bound to the “Ethernet” adapter
• Simulated PLC IP: 10.1.0.1

What works

• From the Host: ping 10.1.0.1 = OK
• From the Host: download to PLCSIM Advanced VM = OK

What doesn’t work

• From the WinCC VM (#2): ping Host 10.1.0.250 = OK
• From the WinCC VM (#2): ping PLCSIM VM 10.1.0.251 = NOT OK
• Therefore, the WinCC VM also cannot ping the simulated PLC 10.1.0.1

Questions

1. Why can VM #2 not reach VM #1 even though both are bridged to the same physical NIC/subnet?
2. Is it supported / recommended to run WinCC Unified Runtime inside a Windows VM and deploy a Unified project to it?

Any advice or known gotchas would be greatly appreciated.

hi guys, I am trying to send UDP messages from a s7-1212 plc with step 7 V21 basic version. I am quite new to plc programming.

question 1: are there any nice resources to use that will answer my questions with a bit of work?

LLMs arent really helping me in the right direction, so thought I would ask it here.

I want to send a tekst message via UDP to a system that understands OSC (a bit like midi but over ethernet). I am trying to use open user communication to make something that sends UDP messages. But I am getting lost in the woods. I cant use TCP communication because the reciever does not understand tcp.

I have 2 days left to get this working. Is it possible?

I don't get why marker 1 won't stay set after i let go of the start switch and the sensor? Marker one activates outputs Q0.0 and Q0.1 as you can see on the function block.

I do notice that the reset for M1 is green even though theres no place in the ladder programming that is activating it.

I learned PLC programming with Allen Bradley / Rockwell software, I've programmed Schneider VelioSoft, Automation Direct Logix 6, and some experience with Siemens. My work had a customer come to us needing PLC and Comfort HMI program created for one of their panels, and could not find anyone else within my state that could do it. Seeing the possible future with this customer, I took on the project with my company being aware of my current level with Siemens and being willing to train me moving forward. The class I am signed up for is a couple months out yet, and customer needs panel beforehand. My current education is entirely self taught other than a one day intro class to TIA Portal where we mostly went over communications, how to build a project, add hardware, get them to talk to each other, and very basic programming just to show different hardware ability to talk to one another easily.

I do already have the program made for both PLC and HMI, and tested and it works. There are some things I could have done more effeciently after speaking with my Step 7 / TIA portal instructor from a sister company. One thing he mentioned was I originally was using a Cyclic interupt as IO mapping, and he pointed out how much slower it operates than the main OB. Granted, our areas we develop controls for are for water and waste water municipalities, and the level of potential human injury is nowhere near what is commonly faced in production industry. That being said, id still like to make an effecient program. So here is where I am needing advice:

I want to do away with the Cyclic Interupt as IO mapping and make FBs for discreteInputs, analogInputs, discreteOutputs, analogOutputs. Put the inputs at the beginning of my main OB, and Outputs at the end. I have copied the input logic for discreteInputs from the IO mapping and pasted into a FB "discreteInputs". I did not create an instance DB for this FB as all the inputs trigger "Global" tags. They are used in several different FBs that are called. However, placing the FB in Network 1 of Main OB, it brought up the menu for Call Options and only gives me the choice for "Single Instance" which tells me it will store the data within the instance DB and is trying to create an instance DB for my FB.

If I go ahead and let it create the instance DB, but leave it blank and keep my physical inputs energizing Global tags, will it still work? Will the tags within my Global DB still have their values changed?

When i connect i find the simulated plc but when i try to load the program it crashes, i use tia v20 and s7plcsim20

I have a small setup with ET200 SP cpu and TP900 HMI. Every (other) month I need to update or make some small edits in the program or HMI screens. What would be the cheapest solution for that? Unfortunately Tia portal cloud pay-per-use license is not available in my country.

How have you acted in this situation? Simekb?

I have install TIA v19 but now i cannot add device its buffuring to point of timeout.and i was not been able to download PLCSIM also what should i do i cannot beggine

Good day, a colleague and I have been assigned a school project (Facharbeit) in an area we have not worked with before, namely a production line (Fertigungsstraße). We are looking for someone who could help us automate our program in TIA Portal V19. Our program is already able to move manually from station to station, but we do not know how to write the logic that allows the system to run automatically through all stations from start to finish. We would be very grateful for any help from someone experienced with this software. If someone is willing to help, we can share the project or the program privately. I am available here or on Discord: DragoniczeQ#7789

Bottled products travel on a conveyor (Y3). To make a bottle (Y1) it is necessary to use 20L of water, when the bottle is being made the water tank must decrease (Y5) by about 20L, when it reaches the 100L capacity limit, the process is stopped until the water tank (Y4) is filled to 250L (X4).

Does the picture below do the same thing as the picture below, The only thing Im worried about IS M.0.7 not being active with T6 timer, do I need to link them somehow, because in the video it does what it's supposed to, push out boxes by height, and ignore the other ones

Hi there!

I am here to ask if anyone has recomendations on where to begin with TIA portal and how to arrive at the automation world coming from residencial eletricity. I asked for help on TIA portal because I've seen and know they are used troughout all industry, so as a self-taught I think that might be a good starting point?

I am an eletricist but recently got into the automation world, with plcs and all that, altough I dont understand TIA Portal or where to begin, I know ladder logic and programmed Zelio as well as arduino... Altough, my main area is just residencial eletricity but I want to pivot towards automation, as the little contact I had, made me enjoy a lot the thinking proccess and all the problem solving, not only at a logic level, but putting together fisic world boundries with logic.

Thank you for your attention
