S7 Loading From Memory Card

We're a Mitsubishi site, but have a few S7's on off the shelf machinery.

One machine we bought has a password on the software, so we have been unable to back up the software. After many awkward conversations, the machine builder has sent us this Seimens SD card (see photos).

When putting this into our laptop, it's only giving us the option to format. Which we obviously don't want to do.

As this is our only known back up, we want to verify that the back up is physically on the card. How can we do this offline without potentially effecting machine in question?

Thanks in advance.

Siemens IPC477D Touchscreen Driver Needed

I have reloaded a IPC477D with Windows 7 64-bit and everything is working but since we do not have the original installation disk or ISO, we have no way to load the touchscreen driver.

I am looking for any information that would lead me to the OEM for the touchscreen or if anyone has access to the IPC installation DVD, all we need is the touchscreen driver directory which should have both the 32-bit and 64-bit version.

Siemens tech support indicated we must repurchase a installation DVD for $350.00 and it would ship from the fatherland and be here in about a week.

Thanks in advance.

I'm new to Siemens software with little PLC programming experience, but the only mechanic with any experience at all.  So here it goes.  Our plant has equipment using S7 1200 PLC (TIA Portal V13 and Startdrive) and three G120C PN drives controlling conveyors.  Currently the drives are controlled through an HMI to control the speed.  We need to be able to slow the speed of these conveyors automatically after an external counter reaches a predetermined set point so an elevator can empty the product and return to the up position then return the speed control back over to the HMI set points.     

We are using a Red Lion counter with a preset count for counting boxes.  When the preset count is reached it will send an output signal to the S7 1200 PLC to slow down the roller conveyors and the counter will reset to ZERO automatically to count the next batch.  After the elevator empties the load and returns to the up position and makes contact with the UP limit switch we need the Conveyors to return to the normal running speed.

Any help would be appreciated.

i want to data log few variables having string data type,but as i know we cannot log it directly in historical data as we do in case of bool,int data type tags.

Software i am using for HMi is (TP900 Comfort) TIA Portal v13 sp1 update 9

and PLC is S7-200 SMART

can anybody suggest how to do it.

I am using TIA Portal V14 to program a Siemens Mobile HMI (KTP900 Mobile).

I would like to pull up a program 'signature' from the HMI that would allow me to verify that the code in the HMI is the correct version.  This would help prevent an accidental overwrite of old code, resulting in a single Mobile HMI that has differing code from several others that are also in use.

The closest comparison would be a Safety Signature from a Safety PLC.  However, I just want to use a file checksum or similar variable that I can put on my screen.

Any ideas?  I appreciate it.

I'm trying to import .gsd files but an error occurs and says : "IntegrationManager: 'xddRootDirectory'-parameter is no valid/exisiting directory !"

The second error that shows is : "Path information incorrect: The string C:\users\name.surname\Desktop\GSD\s0100008.gsd is not a valid path."

Has anyone encountered this problem and maybe found a solution to it?

Hi, good morning, it's my first time working on a project with Siemens, I've always worked with Rockwell and from siemens I only know the s7-200. I have to make a profibus network with master s7-1500 and Rockwell motor starter slaves in a MCC. Someone who can help me or can give me some tutorial that will help me to do this or some document would be appreciated.
 

Thanks

Hi friends could you share me piece of information of integrating some number of PLCs to automate a feed mill industry. should we use any sensor or any physical connection like profibus or profinet to allow sequence of operations of PLC one after the other in mixing, grinding, dosing and palleting. Here we use SIMATIC 1517 for this purpose.

Hi,

I have siemens KTP 1000 basic PN, i want transfer an integrated wincc flexible program into it.

Please what are the wincc soft ware requirements to be able to do this transfer?

what i intended doing is to install wincc flexible,wincc 7.0 runtime and config since i dont have wincc flex runtime.

is this rite?

please help.

Hi all,

I will be starting on my MSc in automation in a couple of days so for that reason i have obtained a S7-1200 series 1211AC/DC/RLY PLC.
This is a new area for me as i have been working in offshore since i graduated from my BSc a couple of years ago.

I watched some Youtube tutorials on how the programming is done and i am ready to try it out for myself, but i have encountered a little problem.

 

Problem:

I am using the X1 P1 PROFINET (LAN) port as a connection to my PC, this turns the Green Link light on and the Rx/Tx lights blinks orange.

Now to the problem, i cannot connect to the PLC through the TIA portal, no matter what settings and connection types i use in the PG/PC interface box.

I have had no luck finding leturature adressing how to configure the PC/software and get a connection to the PLC.

Do any of you have a PDF or link which can help me through this problem? 

Hardware:

S7-1200 series 1211AC/DC/RLY

6ES7 211-BE40-0XB0

S C-J5PN 1614 2017

FS:05

Software:

TIA Portal Version 13

STEP 7 Professional V13

WinCC Basic V13

 

Thanks

 

Best regards

 

Dennis

Hello everyone,

Is there any way to communicate with Mitsubishi Servo amplifier MR-J2S-350CP through RS232 ,I prefer to use 224XP because i already have it...

thank you

heey, i'm stuck at a projekt i'm working on, i need to make a speed monitoring (125 RPM) with a normal input and a sensor.

The plc has to reset a output if it comes under 100 RPM and the continue when it hits 110 RPM, if i dossent reach it in 10 s it has to set an other output.

I have tried a lot of solutions, but the "reset" part gives me som trobles.

I hope that some one can help me :)

Hello All

 

I'd like to display data in 2 or 3 arrays as a graph on a KTP400, does anyone know of a way to do this, I know I could use a trend display , the only issue I have is that the array will be updated in around 10 to 20 msecs per element, and as far as I am aware the time between the trend values need to be 1 sec or more.

Any comments would be appreciated.

Hi.

I would like to tell you about a modbus library I have made and recently released, for Siemens S7-1200 PLC's. I made concept that called Station block which is mapping of registers for one specific modbus rtu device. Station blocks can be made very quickly and can be easily be reused and combined with other station blocks. The library is free under the MIT-license and can be downloaded at github (link bellow). Please check it out, I would like to get some feedback on my work.

https://github.com/olab84/rexhip/

An modbus rtu example:
#mb_master_ctrl(hardware_id := "Local~CB_1241_(RS485)", 
                               baud := 19200, // bps                
                               mb_query := #mb_query ); 

#mb_query(mb_addr := #mb_addr,                  
                      mode := #mb_query.c.read.input_reg, 
                     data_addr := 13,                      
                     data_ptr := #resault_data_1);  

#mb_query(mb_addr := #mb_addr,                 
                     mode := #mb_query.c.write.holding_reg, 
                     data_addr := 55,                            
                     data_ptr := #resault_data_2);

// - The library will take care of execute each query, one by one. 
//    Add as many queries as need. (There no need of a state machine)
// - Queries belonging to one device can be placed inside one FB,
//   this FB can later easily be reused.
