Any one please give solution for following questions.

1)Hardware configuration for getting 10 analog inputs in

SIMATIC S7-300

2) Program for reading the pressure from quantity-10 gauges using analog communication. All the gauges should have one generic function block which is called up for 10 times

Hi,

- What is the range of your gauge ? 0-10V, 0-20 mA, 4-20 mA ?

Regards.

..maybe rather ask:
How much do you pay for us to GIVE the hardware configuration and program?
Or do you need guidance to do it yourself?

Other details also lacking..
* sensor specifications?
* conversion resolution required?
* Which software? Step7 V5.x or V1x?

......

 Hi thank you for your reply

I need guidance

I need to know is it possible to add 10 analog input and output in CPU 315 DP -2 module

Thank you very Much Dchatier 

I think you are Expert in PLC Programming

I need one more help

In Siemens step7

1)May i know how to setup hardware for 10 analog input and 10 analog output  in CPU 315 DP 2

if its not possible means which CPU setup is convenient for 10 analog input/output

Analog Communication

2) How to program for reading the pressure from quantity-10 gauges. All the gauges should have one generic function block which is called up for 10 times - please help to create it.

May i know for this one we need Scale or some other option.

Hello Licary;

Setting up and programming analog input sensors requires a few steps:

- selecting the appropriate sensors for your application, and determininig the type of analog signal that will be used to connect to the PLC (0-20 mA, 4-20 mA, 0-10V +/- 10 V...).

- choosing the correct analog input card for your PLC, one that supports the analog signal provided by your sensor. This will often require some kind of configuration, either through the wiring, the positionning of a range module (on the side of the analog input card) or parametrization in the HJWConfig editor. You must find the appropriate documentation for your analog input module 9we can help you there).

- connecting the sensors properly to the selected analog input card, respecrting shield and ground connections (again based on the documentation for the analog module).

- finally, converting the raw values that the input sensors provide to the analog input module into engineering values that actually mean something to your project.

Say your sensor provides a 4-20 mA signal to the PLC. The PLC analog input card uses an electronic circuit named an A/D converter (analog-to-digital) to transorm this into a numerial value 0-27648. That is 4 mA will become a value 0, 20 mA will be represente dby the number 26748, will all values in between being proportionnal to this range.

But 0-27648 does not mean much to you. You would rather have 0-100%, or 10-350 gpm, of 200-20000 cfm... There is a standard block for this in the Siemens program Library, FC 105 "SCALE". when you are rady to program it we can also help you.

In the mean time here is a bit of information for you.

SIMATIC S7-300 S7-300 Module data

Look at the chapters on Analog representation and modules for detailes information on the hardware and configurations available for a S7-300.

How and for which analog measurements can you use the function FC105 'SCALE' to convert the integer values (INT) into real number values?

and finally, for a complete tutorial on  analog value processing, open the following link, and look at this module

B2- Analog Value processing

Hope this helps,

I think its come 0-10V

 Hello Licary,

Sure that you can control 10 Analog Input and Output with CPU 315 ... But what you want to do? Our Expert dchartier, he has already given to you information as scale the values.

 Hello Daniel Chartier

I attached my hardware config screen shot please check it

Thank you for considering me

Hello Licarry;

To answer the basic question: can you setup 10 analog inputs and outputs on a s7-315-2DP, the answer is yes, very easily.

You already have most of the answers in the post above, please take them one step at a time.

You now seem to know that the analog sensors will provide a 0-10V signal.

Next you need to select analog input modules of the s7-300 family that can read these signals, Open the s7-300 module data manual to the Analog Modules chapter to choose a conbination of modules that will give you 10 or more analog inputs, all able to read 0-10V; select the appropriate analog output modules based on the range and type of signals you want to generate.

To start your program you need to work in Simatic Manager (Step 7) with the HWConfig editor to setup the hardware configuration of the PLC. This will tell the CPU what modules and analog channels will be connected on the rack and what addresses will be linked to each analog input. This will be useful later when you want to read and scale the analog inputs.

If you have little experience with setting up a hardware configuration on a S7-300 CPU, open the tutorial link above, go to the Basic Programming tab, and open module A4-  Programming a S7-315-2DP. It starts with a hardware configuration example that you can follow and apply to your project (just select the correct module part number in the catalog).

Enough for now, I think. Once you have gone through these steps and are ready to start a small programm, take a screencapture of your HWConfig editopr so wecan see how far you have gone, and we can help you with the next steps.

hope this helps,

Daniel Chartier
