Hello,
I am using S7-200 CPU 226, but it is password protected of Level-3, therefore I am unable to upload the program kindly tell, me How I can?
I am using MicroWin 4 software and programming cable (USB to RS485) to communicate with PLC
I have used a software to crack by brute method but it is consuming a lot of time i.e a month required to crack.
Please helppp me
All,
I am using Keyence CV-X422A vision controller for my application. It is interfaced with Siemens S7-1500 PLC on PROFINET. I am able to communicate with Vision controller through PLC logic command and status IOs.
There is some communication issue in updating the o/p values from Camera Controller. I have tried with & w/o Handshake Mode with these settings. The camera display shows the reject but camera never turns ON the NG Status o/p.
I tried different things told by Keyence Tech support but none of them worked.
He told me to have you enable the “Result ACK Flag” in the bit allocation area and send a signal to it. Then trigger it again with a no good part and see if that fixes the issue.
I tried setting the “Result ACK Flag” to 1 after I get the “Command Complete Flag” for the trigger signal that I sent. Sometimes this works but still it is not reliable. Do I need to send only a pulse to “Result ACK Flag”?
Anyone here has ever faced similar issue?
Thanks for your help.

I recently purchased the SIEMENS CONNECTION KIT (6ES6400-1PC00-0AA0) with its corresponding serial cable to connect to a MICROMASTER 440.
I connect my RS232-USB cable to the serial cable. But I can not connect in any way!
What do I do wrong?
1. In the micromaster 440 I put the following USS configuration parameters (USS = serial communication):
p2010 = 6
p2011 = 0
p2012 = 2
p2013 = 127
2. I put the DIP of the Connection Kit (Ref. 6ES6400-1PC00-0AA0) 1 ON, 2 OFF, as indicated in the manual.
I connect the connection kit module with its serial cable to my RS232-USB cable. And I connect the USB to my PC.
3. Open "Set PG / PC interface" and select PC COM-Port.USS.1
4. I go to the properties and I am selected COM1 without problems.
5. But I do the transmission speed test and can not find anything.
6. Also in the diagnosis of PC COM-Port.USS.1 I do the test and can not find anything.
Supposedly my RS232 cable is correct (I have tried several tests).
And the configuration of the COM port in "device manager" also looks correct.
What am I doing wrong??
Zhanks!
,The '"System".Cycle.InCycle' parameter is not permitted. No access is allowed to static I-DB variables. Remove this access from the safety program.,,,10:27:41 AM
can anyone shed any light as to why this would appear all of a sudden, worked perfectly well the last time i was onsite. did someone connect with a newer version of step 7 safety? any ideas?
Hi,
I'm having issues with my S7 rack communicating via modbus to another device which is the master.
I'm a total noob at this and I would like to change out the modbus card in the rack(6ES7 341-1CH01-0AE0).
My question is, do I just simply swap the module, looking in the hardware manager of my project, I can see that the card has specific parameters,A
re these stored on the PLC and will just simply be written when the rack powers up or do I need to program it?
If I need to program it, how would I go about it?
Also, is there any specific tool in Simatic Manager that I could use to check that the modbus card hardware is operating correctly and the comms are stable?
Thanks in advance, Colin
Dear All,
Hello everyone! Been a few years since posting on this forum but I have a question and though that one of you might be able to help.
We have a Siemens 1200 on a ship and every now and again the PLC goes into STOP mode. I'm not sure the reaon why it does this but I believe it may be due to a power outage or power surge, maybe it think that a card is not present or something. In any case, it means I have to go and visit the ship, plug in my TIA Portal V12, go to online and click RUN CPU.
My question, is, is there a way to program the PLC so that under no circumstance the CPU will go into STOP mode? Can I maybe use a OB to force it to always stay in RUN mode even if it sees hardware errors?
Thanks for any input.
Cheers,
Ben

Good morning all!
I'm just getting into this world of controls and automation and need a way to simplify my life when it comes to discrete alarms. I do not care to separate them by tag so long as I can create a personalized for each bit/alarm triggered.
I understand I can use something like a tag of data type word, such as "Faults" MW100 and then reference M101.0, M101.1... M100.0, M100.1 (notice the order), but this only allows me 16 total discretes per tag. Sometimes I'll have more alarms than 16 and sometimes way less. I'd rather not seperate them in this manner if I can avoid it.
Your assistance is much appreciated!
[edit] Siemens TIA and WinCC v15
Could someone refresh my memory how bit instructions works in STL in Siemens.
A M 0.0
L S5T#2S
SD T 0
= Q 0.0
Status of Q0.0 depends on RLO of A M0.0. If I modify a program little bit:
A M 0.0
L S5T#2S
SD T 0
A M 0.1
= Q 0.0
Now status depends only on RLO of A M0.1, not on A M0.0 anymore. How's that?
Siemens manual says: You can terminate a Boolean bit logic string by using =/S/R, which is not this case.
I'm sorry, guys, but I wouldn't be asking if I hadn't dedicated about 12 hours to this already. Long story short: ACS800 with RPBA-01 Profibus Adapter and RTAC-01 Pulse Encoder Interface. All we send to the drive (aside from CW permissives) is a position reference, and I believe the DriveAP functions execute how the drive will achieve that position. My final aim is to separate the encoder from going back to the drive, to instead going to a FM350-1 Counter module.
I'm following someone elses work that is long gone, has been changed multiple times, and comments are almost non-existent.
Where I'm stuck is understanding the data coming from the drive and being sent to it.
PPO Type 5; DPV 0. In Step7, I have a DB for 20 bytes of data to drive and another DB for 20 bytes received from drive.
I understand (with respect to data from drive) that it should be: SW; ACT; PZD3...PZD10 (10 x 2 byte Words).
But, when I looked through all the settings in the group 51 parameters, the values in the form of (xxyy; index then subgroup; ex: 106 is parameter 1.06) don't seem to exist in the ACS800 Firmware manual.
PZD 3 OUT: 7 --- PZD3 IN: 6
PZD 4 OUT: 8 --- PZD4 IN: 10
PZD 5 OUT: 0 --- PZD5 IN: 106
PZD 6 OUT: 0 --- PZD6 IN: 0
PZD 7 OUT: 0 --- PZD7 IN: 611
PZD 8 OUT: 0 --- PZD8 IN: 612
PZD 9 OUT: 0 --- PZD9 IN: 701
PZD 10 OUT: 0 --- PZD 10 IN: 706
The manual says parameter values 1-99 refer to a "Data Set" and each number specifies a certain word in a Data Set. For example, PZD3 IN: 6 refers to Data Set 2 Word 3, which is defined by paramater 92.03. But, that turns up something about short circuit protection, when what my DB value is displaying a distance (from a linear string pot encoder) that matches what the mill is actually at. The ACS800 manual says Data Set Actual Signal words are defined in Group 92. So I looked there:
92: DS Transmit (From Drive) --- 90: DS Receive (From PLC)
92.01: Status Word (Fixed) --- 90.01: 4501
92.02: 103 --- 90.02: 4309
92.03: 402 --- 90.03: 4505
92.04: 412 --- 90.04: 1
92.05:106 --- 90.05: 3
92.06: 0
Any help would be appreciated. Thank you.
Hello,
hopping somebody can help, not sure if this has been spoke about before on here or not.
please point me into the direction if it has.
I'm looking at creating a user log on and password section.
Example -
User Inputs User Code and password. - the User code is then put into a VLOOKUP in the DB to find the associated password. if correct displays said users data.
has anybody done/seen this before. I've generated it via Ladder but its very long winded and if it comes to having multi users (+50 its a lot of copy and paste).
Thanks in advance.

I uploaded PLC program from S7-300. It has a profibus slave with
GSD file:"WELLE__X.200". I cant find this GSD file in the website.
I want to add one ethernet card and download the updated hardware configuration. Therefore I need to install the GSD file.
Anyone has this WELLE__X.200 GSD file? Thanks
Hi, i have a system with 2 plc´s (cpu 222 and 226) and a siemens touch pannel. the console communicates with the 2 plcs. However, when i try to do a NETR from one PLC to another, the PLC which does the NETR (CPU 222) stops communicating with the console, but communicates with the other one (CPU 226). How can i resolve this problem without having to give up the communication between the two PLC´s
Thanks.
Hi,
Any body with the idea how to configure and calibrate Disomat Schenck process on a weighing bridge system
integrated to S7 400?

Hello,
I am not very experienced with Siemens PLC's
I want to change program in one S7-200 CPU 226 (profibus).
I have never connected my laptop to it before and I don't have that PLC's program. I have PC Adapter USB A2 cable for that and V4.0 STEP 7 MicroWIN SP7 program.
I connected the cable, opened the program and tried different settings for connection, most of times the test in diagnostics says that status is OK.
But! in communications window when ever I try to refresh the adapter is gives me error: "Class not registered"
So I'm not able to upload the program from PLC to my laptop.
Can anyone give me support?
Hi all,
I'm kind of beginner regarding Siemens PLCs. I have to buy an interface that allows me to program and monitor an S7-300 plc with profibus interface.
So far I have utilized a Helmholz NETLink® PRO Compact, PROFIBUS Ethernet gateway 700-884-mpi21.
My question is: what other options are there?
Thank you
Working on my first Siemens project. Called tech support and they sent me a link to a software download. But, I need to register on the Siemens website for this. For some reason I can not register! I've tried using Internet Explorer, Firefox and Google Chrome. I put in all my info and then the website either freezes up, or it says the "nickname" I chose was already in use. I've tried at least 10 different "nicknames". Some of them were just random combinations of letters. I don't see how this is possible. Anyone else have this problem?
Working on my first Siemens project. It's supposed to be a S7 PLC with a TP-1200 HMI (Comfort panel). What software is used to program these? Can I use TIA Portal for both the PLC and HMI programming? Or do I need Win CC for the HMI? Also, what is SIMATIC Step 7 software, is this obsolete? Thanks in advance.
