I need to catch an input changing state which has a very short duration and I'm currently missing it due to scan time. Is there a way in Siemens to improve the chances of catching a change by programming e.g. using something similar to a Selectable timed interrupt (STI) from the Allen-Bradley world or maybe a FAST TASK?
Thanks in advance for any suggestions
I've used Allen Bradley for 10 years but never used Siemens, I might have to work on a Siemens project soon, it's supposed to use the S7. May be a stupid question, but what do you guys suggest to help learn Siemens programming/troubleshooting? Any articles/links etc would be appreciated, thanks.
Hi all!
I want to convert programe from S5 to S7
How to way upload programe S5, type cable and software can i use?
I have laptop (PCI Express to Com), PC adapter USB A2, software PG2000, S5S7 for window, SIMATIC MANAGER V5.5, TIA PORTAL V14.
Please help me!
I need to know what port or port range that's used when programming a 1500 CPU.
We need to update the settings of the CPU, and the customer can open up a router with "port forward" if I tell him what port to use.
Does anyone here have the knowledge about what port or ports that are used for the 1200 and the 1500 systems ?
Hey there Seimens experts,
I have a few little S7-200s and need to backup the program on them.
What software and cable do I need.
I also have a few Micromaster 440s that I can back up too if the cable and software is not to much dollars.
Thanks in advance,
Hi All ,
I am trying to recreate this Traffic light Program with HMI from youtube here is the link
https://www.youtube.com/watch?v=vEYuvYFuTHo
I have also written the program in TIA 13 (OB1 Network 13 not clear to me ) but the HMI part is not complete . I need help to recreate this Program and fully working
dropbox files link
has the program i have written and the video from the youtube and some screen shots , I am working on the HMI will keep uploading the updates to the same Dropbox Link

Hello:
Has any body encountered Profinet IO cyclic communication establishment problems between the latest S7-1500 PLC with firmware 2.0 or later and non-Siemens Profinet devices which had previously passed conformance testing campaigns?
Thanks for your comments.
There is a standard view called "User view" that you can drag in to your HMI project on TIAPortal.
It allows you to create new users, and edit users during run-time (i.e. from the HMI screen itself, not from your laptop).
However it is not clear if/how you can delete users during run-time. Does anyone know how to do it?
Thanks in advance!
I current have 2 variable: Displacement vs Pressure. I need to draw a real time graph on Comfort Panel. The problem with using just f(x) trend is that the minimum time between updating a point is 0.5 sec and that is for ever in my application as the whole cycle last only 5 sec and I have to plot 500 points in that time.
Is there a way to do real time graph using Historical data without any time delay. If anybody can guide me through any sample program or material would e helpful.
Thanks
I want to write a script that will download a specific function from a program to an S7-300 PLC.
I saw that it is possible with the Command interface (via VB) but the help is not very clear.
What is the commad to download a specific FC (for example FC100) to the PLC?

Hi everyone!
I have inverter G120 0.75kw (6ES3224 0BE17 5UA0), card CU230P-2 (6SL3243 0BB30 1HA3), BOP-2 (6SL3255 0AA00 4CA1).
I want to run inverter via Terminal DI 0, change frequency inverter via BOP.
I have run inverter but i can't change frequency via BOP, please help me how to way change frequency via BOP.
Micromaster 420, 430, 440, v20 i'm set parameter P700 =2, P701 =1, P1000 = 1 then i can run inverter via terminal and change frequency inverter via BOP
Thanks!
I am getting a flashing arrow on the simatic panel and line won't run. Cleared all faults and line still won't run, just has a flashing arrow pointing to the right on the panel. Any help? This is for a Siemens application.

Hello Everyone,
Our machine with PLC CPU 1214c, was program last year using TIA V13 professional. Now i need to add some Expansion module for additional sequence, but i only have here a TIA V13 basic. When i tried to search the hardware; yes it can be searched, but it will not upload the existing hardware (CPU+ other modules). My question is, if the s7-1200 PLc was programmed by TIA v13 professional , does it can only be edit by TIA v13 professional? is there any chance that the basic version can edit the programmed.
Thank you all in advance for your answers...
Hi everyone!
I have a problem in STL (using step 7 V5.5 + SP3 version).
Every second I need to read the actual input value and store it in specified memory (MW 2204, MW 2206, ... MW 2222).
After 10 seconds (10 values should be in the memory) I have to do an average of them.
And my question is: how to place this 10 input values in this memory?
Hey Guys,
I have hit a bit of a road block. I am trying to get my TP700 comfort panel to talk to my AB SLC-504 CPU using a 1761-NET-ENI module but it will not talk. I can talk to the CPU through my switch with the computer but the HMI just zones out. If I slap a 505 CPU into it the HMI communicates fine with it but for some reason it has issues with Ethernet communication through the ENI module. Has anyone else been successful attempting this?
I know you must be thinking "Why not just use the 505 and be done with it?". I would if I could. All of the test work has been done at my workbench. When I tried to install the 505 into my machine it comes up with programming conflictions so I have to keep the 504 in it. Hence my attempts at using the ENI.
Thank you for any assistance

My name is Mariusz Suder. I'd like to present the new process simulator PSPLC.
PSPLC this universal process simulator can be used for building various technological models.
PSPLC - is designed to work with PLCSIM v 5.x the part of Step7 and TIA Portal the Siemens™ PLC programming environment.
There are plenty of typical devices and parts of industrial installations to choose which can be easily put or laid on the screen by simply selecting or dragging them. (...)
PSPLC is the reliable process simulator. Useful for testing the PLC programs while they are executed or for learning programming the PLC controllers.
Due to the intuitive user interface building models is quick and setting the devices easy.
Colourful graphics, animations and high quality simultaneous sound.
Language versions: English, Polski, Deutsch, Русский.
Two units systems to choose: Metric and British Imperial.
OS: Win XP, WIN 7
For further information please visit my internet site:

PSPLC can also be downloaded from: mrplc/download/siemens/demo

First, I am pretty new to function blocks. I somewhat get that you can create a function block and use it in multiple places to control similar functions. I am working on a program that someone else created. It uses a function block to control a variety of servos. What I don't quite understand is how it is determined what outputs to use. The system uses profinet. I watched a couple videos, but they really didn't explain anything....they just showed how to make a simple function block with no dialogue.
More importantly. and unrelated, I need to somehow export some data (scrap and production counts) to a CSV or via ftp to a computer. I am using TIA Portal V13 with WinCC Comfort. I've done similar functions in the past using Automation Direct and Proface HMI's, and they were much more intuitive than the Siemens.
Thanks,
