Dear sir Engineer,

hope you will be fine,Actually we have a project S7-400H and PM1200 and PM500 i was wondering how can i read data from this Devic?Do you have special User manual for helping?

 Dear Vahid

first of all, do you have communication module connected to the S7-400? do you have your pm1200 connected as modbus slave (pins 7 and 14)?

if yes then look at this manual and tell us which data you want to read and there addresses. then someone of course will be able to help you

your question is general and you have to write more details about the device and the data you want them from it

Dear sir T_Ebrahem,

really appreciate it for your reply,as matter of fact we have Remote IO With ET200M,And in this RIO,We have Bought this Module:

6ES7341-1CH02-0BA0

6ES7870-1AB01-0YA1

we wanna to read Data Like:Power factor,Current,Frequency,...

Could you help me what Hardware configuration is necessary?And explain about Communication.

Regards

Hello Vahid-T;

Your question requires a bit of thought on our part, and a lot of study on your part.

The CP 341 you have in your project is a serial RS-422/RS-485 communication processor, which is fine for your project, as it can communicate with both PMs on a single network.

To talk to the PMs, you will need to implement the Modbus RTU protocol with a special "downloadable driver", accompanied by the hardware dongle that you must insert in the CP 341. The part number you show only contains the dongle, and a Slave dongle at that:

6ES7870-1AB01-0YA1

S7 driver f. CP 341, MODBUS SLAVE,w/o SW

SIMATIC S7, MODBUS Slave V3.1 single license for 1 installation R-SW, without SW and without documentation, HW dongle, Class A, 3 languages (de, de, fr, en fr), executable in STEP 7 V4.02 or higher, reference hardware: CP 341 and CP 441-2.

Normally the part number suggested for your application (the CP 341 is the master on the Modbus network) would be this one:

6ES7870-1AA01-0YA0

S7 driver f. CP341, MODBUS MASTER, EL

SIMATIC S7, MODBUS Master V3.1 single license for 1 installation R-SW,SW and DOCU on CD,HW dongle, Class A, 3 languages (de, de, fr, en fr), executable in STEP 7 V4.02 or higher, reference hardware: CP 341 and CP 441-2

There may be a way around this problem, as I believe the dongle can be interchanged between master and slave settings, and only enables the Modbus functions on the CP 341. You could download the CP 314 PtP parameter software and the Modbus master driver directly from Siemens and attempt to make them work together with the dongle you have ordered:.

- Loadable driver "Modbus Master RTU":

https://support.industry.siemens.com/cs/ww/en/view/27774018

Once you have the hardware (and software driver) ready, you need to work on the Modbus master setup and programming on your CP 341.

First, you must be familiar with Modbus concepts, as it was developped for Modicon PLCs a long time ago, and still requres use of Modicon addressing and functions. Our friend smiffy has prepared a document that has helped many here on the forum integrate these concepts:

- Modbus General Description:

https://support.industry.siemens.com/cs/ww/en/view/1220184

Next, here is the manual explaining the Modbus master driver and the functions required to connect to the Modbus slaves and request data from them, along with an Application Note from Siemens Support showing an example for such a network:

- Modbus RTU loadable driver for CP 341:

Finally, in order to locate the addresses of the registers you are trying to read on your PMs, here are the operating manuals for each:

Hope this helps,

Hello 

Daniel explanation should be enough to understand how to configure your project. here also you will find  a project from uel123 same as your case, you just need to change it to your needs, for example the LADDR and the start address for your data and the length. 

as I can see from your slave manual, the start address is 3001 decimal. so take a look and try and if you cannot go further then please explain your issue.

Dear sir Daniel Chartier,

really appreciate it for your complete answer.But I have some more questions about your explanation:

according to your comment, you mentioned that i have chose wrong Order?As i wrote we have S7-400H(CPU 414-5H),But  our Remote IO contains ET200M and all Modules Are S7-300(Like IO).

any way i chose wrong Order?Because i just wanna  read data from PM1200 ,according to that i chose:

6ES7341-1CH02-0BA0

6ES7870-1AB01-0YA1

 also my software is Step-7  Professional 2010,Know what should i do with this?Should i change My License(6ES7870-1AB01-0YA1) with Master?Should i pay money or that is free for Download?Which version should i download because your link contains 7 version up to S7-5.6.

Best regards

Dear sir T_Ebrahem,

Really appreciate it for your answer.I have explained about my issue.You can give me your view point about my order and problem

regards

Dear sir Kaulquappe ,

unfortunately i didn't receive answer of  my question.I have S7-400H and i wanna read data from Pm1000 by means of ET200M in Remote IO,Now i choose these order:

6ES7341-1CH02-0BA0

6ES7870-1AB01-0YA1

but Mr "Dchartier" had told before i should have chose these order 6ES7870-1AA01-0YA0,At the end he told me :("There may be a way around this problem, as I believe the dongle can be interchanged between master and slave settings, and only enables the Modbus functions on the CP 341. You could download the CP 314 PtP parameter software and the Modbus master driver directly from Siemens and attempt to make them work together with the dongle you have ordered:"),but i couldn't  understand how can i change?my software is Step-7  Professional 2010,Know what should i do with this?Should i change My License(6ES7870-1AB01-0YA1) with Master?Should i pay money or that is free for Download?Which version should i download?

Mr Dchartier put some link for PTP Parameter and Loadable but the all version are for  S7-5.6

Now could you please explain very simple step by step what should i do?Is there one practical sample Manual or example?

regards

hello Vahid

I see you still you dont know how to proceed. one thing I want to understand. you bought the license and the module. are you still able to replace or return them? also what is the model of your S7-400 cpu?

please answer these questions and then I might be able to help you with your setup.

regards
