DenisRus Posts: 7 Rating: (0)	Hello, I need help!!! I want to make a network communication with S7-300(CPU 317-2 PN/DP) and S7-200(CPU 243-1) via industrial ethernet. I want to read data from V3600 ...V3612 (S7-200). I have readhttp://support.automation.siemens.com/WW/view/en/17369594. But it has not helped me .There can be I set not that TSAP?

For the I used one ET 200M module at the S7 200 station. I downloaded the ET 200M GSD(Generic System Discription)file from SIEMENS forum.I inserted the ET 200M in S7 300 hardware configuration, then in the properties of the ET 200M I gave the Mapping address for the Variable bytes at the S7 200 to Memory Bytes at S7 300. (Ex. VB1000-1020 => MB 0 - 20) The information about the above things in details you can get in the ET 200M manual. I hope thing the same settingswill be there for Ethernet communication.

In the link you provide, different TSAPs (Transport Service Access Points, an OSI tool for identifying the interconnections between the data layer and the transport layer of the ISO 7-layer communication model for Ethernet) are proposed depending whether the S7-200 is server or client, and the S7-300 is server or client. Look at the following discussion that we had here last month, especially at Helmut and J_Bell's explanation of the TSAPs used with PC-Access (an OPC server for the S7-200); it might explain some details: /tf/WW/en/Posts/26160 So please tell us how you have selected the server and the client in your application, how you have set them up in MicroWin and Netpro (Step 7), and then how the TSAPs required are not possible to write in. Then we might be able to sort the problem out with you. Hope this helps, Daniel Chartier

In NetPro you select the CPU in the S7-300 station and add a new connection. Select for the connection partner „unspecified“ and for the connection type „S7 connection“. In the property view of the S7 connection you activate the function „Establish an active connection“. Enter the IP address of the CP243-1 for the Partner: 192.168.0.37. The IP address of the CPU317-2PN/DP is 192.168.0.5. TSAP of the CP243-1 is 10.00. TSAP of the CPU317-2PN/DP is 10.02 (Here tried to use 10.00, 10.01,10.02, 03.00 ). Tried to use different variants of function call GET. Has as a result simplified an example an example 18610307: Has created in OB1 function GET call: CALL "GET" , DB14 REQ :="req" ID :=W#16#1 NDR :="nrd" ERROR :="error" STATUS:="status" ADDR_1:=P#DB1.DBX3600.0 BYTE 13 RD_1 :=P#DB200.DBX0.0 BYTE 13 Has created DB200 (The DB200 size is equal 13 byte). In WinCC flexible the tag “req” has connected with the button. All bytes of memory are equal in a runtime mode to zero. ERROR->1, STTUS->1 . And there is no somewhere a project with an example of usage of function GET for reading from the controller S7-200?

J_Bell Posts: 5822 Rating: (412)	Dear Denis, I am sorry but if you do not have access to the S7-200 program we already have the problem. You need to configure a S7 Connection with the Ethernet or Internet Wizard within MicroWin. Sadly the S7-200 is not useable just like the S7-300 or 400, so it is not possible to "just" connect to the S7-200 like with the larger S7 systems. So if you are not able to change the S7-200 I see not much chance to get this system running. Best regards J_Bell

J_Bell Posts: 5822 Rating: (412)	Hello Denis, well, as we have no chance to see the PLC program pleas ask the developers they should offer you the parameters they set in the Wizard. What we need from both PLC’s for the S7-Connection is: Local IP and remote IP Addresses. Local TSAP and remote TSAP. On S7-200 additionally Server or Client Connection On S7-300 additionally active or passive Connection establishment. Sadly we have no other way to see anything without the projects. By the way, what ar the names of the PUT and GET functions you use? Best regards J_Bell

DenisRus Posts: 7 Rating: (0)	If I have correctly understood that such ar the names: "req"- M14.1 "nrd" - M14.4 "error" - M14.5 "status" - MW60

J_Bell Posts: 5822 Rating: (412)	Dear Denis, I am sorry but these are neither IP Addresses nor TSAPs and also no information's about the way the communication will be established... I am sorry. Just setting the Parameters of a function and hoping it works is not going to be successful as long as the connection is not established. Best regards J_Bell

DenisRus Posts: 7 Rating: (0)	IP the address and TSAP to me founders of the project for S7-200 have told. It turns out, what something on S7-200 is made not how they speak?
