Hi,

[snip]

I want to communicate a S400 PLC (step 7 v5.5) with a S1500 (tia portal v13).

I want to transfer data from S400 PLC to S1500 PLC using Profibus (I don't have choice). After, the  information will be transmitted to supervisor (scada).

I have been researching how to make communication between both PLC and the only thing that I know is this:
 

1. In the S1500 (tia portal): Declaring a  S7 liaison to the S400 PLC. Created fonction PUT & GET.

2. In the S400 (v5.5): In the protections, authorize the PUT & GET. Besides, the DB should not be optimized type.

I have not been able to establish communication. Do you know another method to do it? Or maybe I'm wrong at some point. As I can communicate?

Kind regards

hi,

PUT/GET should work for that kind of communication(S7-400/S7-1500).

As you can see in this manual:

CPU-CPU Communication with SIMATIC Controllers

an other method is to declare one of the CPU´s as a slave of the other.

Hi ICOMR,

perhaps these FAQ helps you.

Please note:

under properties of you S7-1500 CPU you must enable the connection mechanism "Permit access with Put/Get" at "protection".

How do you configure and program an S7 connection and the PUT and GET communication instructions for data transfer between two S7-1500 CPUs?

Hi everybody,

I will try to be clearer. I take the time to take some screenshots (please see them).I have realized the parametization of my network (PLC1 S1500 and PLC 2 S400 ).  I'm using Profibus communication. I'm using GET and PUT functions. But I get a lot of errors. I have many doubts, but I wonder if in my main program (tia portal s7-1500), I must declare all DB corresponding to another program (s400). Please see the photos. If you have some similar example, send me.

Thanks

hi, 

The errors at the function GET are:

- Not the same size: 1st is 1100 boo the 2nd 1000 bool

- Is the pointer onADDR_1 "JGR_MOD_M_ETAPE0" a bool?

- The pointer syntax on RD_1 misses a point P#DB1.DBx10.0 Bool 1000 would be right. 

hope this helps,

regards

Hi,

I would like to suggest you test your project with some little changes / checks:

1 - Use pointer of data type BYTE, (don't use BOOL)

2 - Check if the S7-1500 DB's has the attribute "optimize" unchecked.

3 - Build the connection without a S7-400 representation in the Network view (go directly to connections and create a unspecified connection with the S7-400, TSAP 03.0+CPU S7-400 Slot number

Thanks for you answer,

Your suggestions have improved the project, however, still have problems. The protocol used is PROFIBUS, so I would like to know what settings to make in my project. Did I perform the same procedure on my project step 7 (s400)? If you look the photo 2, you will notice that the PLC2 (s 400) is not recognized.

Please see the attached file.

Thanks very much

HI,

Still with the communication with the S400 & S1500 PLC (GET PUT fonctions), but is working.... I Wonder, how much I can send & recive using the GET PUT blocks.

Thanks

Hello, I am trying to program blocks PUT & GET to share information among different API. To activate the application in the PUT & GET blocks, I use CLOCK_1Hz, however it does not work. Do I have to use rising edge ?(if yes, there is a specific function for that?)? or I have to  setting my CLOCK_1Hz in some spesifically way (exo: Bit memory system and cadence?). See screen shot attached.

Thanks
