Question Answer Wie konfiguriere ich die S5-kompatible Kommunikation zur SIMATIC S7 für eine Anwenderapplikation über Industrial Ethernet mit der SIMATIC NET PC Software? The instructions and notes listed in this document provide a detailed answer to this question. V /19

3 1 Assignment of tasks In this example a CP1613 is used, that implements the S5-compatible communication to the S7 station on Industrial Ethernet. NOTE The method described in these instructions also applies to the CP1613 A2, CP1623, CP1612, CP1512 communication processors and commercially network adapter. 1.1 Condition Further engineering software isn t required for the PC. All relevant software will be installed automatically with the SIMATIC NET PC software. If you use a CP1613, CP1613 A2 or CP1623 you will need the license key for the SIMATIC NET PC software S on your PC station. If you use a CP1612, CP1512 or a commercially network adapter you will need the license key for the SIMATIC NET PC software SOFTNET S7 Lean or SOFTNET S7 on your PC station. V /19

4 2 Configuration of the PC station After successful completion of the hardware and software installation of the SIMATIC NET CD and the configuration tool and after restarting your computer, you start the the configuration console with Start (in Windows XP: All Programs ) SIMATIC SIMATIC NET Configuration Console or using the desktop icon of the same name. Figure 2-1 setting the IP address of the CP1613 In the Configuration Console you set the IP address and subnet mask of the CP1613 under SIMATIC NET Configuration Modules CP1613 Address. In this sample program the IP address of the CP1613 is V /19

5 Figure 2-2 setting the access point In the Configuration Console double-click the entry CP_H1_1 under SIMATIC NET Configuration Access points. The property view of the access point CP_H1_1 will open. Figure 2-3 property view of the access point Select the available interface CP1613(RFC1006). V /19

6 Confirm the settings with OK. NOTE If you use a commercially network adapter instead of a CP1613 you will select the interface TCP/IP commercially network adapter. All further parameters like local and remote TSAP, IP address of the communication peer and connection parameter are entered in the application. No additional settings are needed in SIMATIC NET PC software. In the sample program the following parameters are used: Table 2-1 Parameter IP address of the CP IP address of the communication peer (SIMATIC S7) local TSAP remote TSAP AAAAAAAA AAAAAAAA Value The connection is established actively from the PC station. Therefore it s necessary to set the PC station to active connection. V /19

7 3 Configuration of the connection for the SIMATIC S7 In the example a SIMATIC S7-300 station is used. The ISO-on-TCP protocol is used for the communication to the PC station. NOTE The method described in these instructions also applies to the SIMATIC S In the SIMATIC Manager you have to open the STEP 7 project that contains the configuration of the SIMATIC S7-300 station with the menu command File Open. Figure 3-1 opening the STEP 7 project Confirm the selected project (in the example: FAQproject_IE_SR ) with OK. The project will be opened. V /19

8 Figure 3-2 STEP 7 project Open the hardware configuration of the configured SIMATIC-S7-300 station. Figure 3-3 hardware configuration of the SIMATIC S7-300 station Now you have to open the property view of the CP Therefore doubleclick the configured CP343-1 in the rack. V /19

9 Figure 3-4 property view of the CP343-1 In the property view of the CP343-1 you have to click the button Properties. The following dialog will be opened: Figure 3-5 entering the IP address of the CP343-1 V /19

10 Here you enter the IP address and subnet mask of the CP In the example the IP address is configured for the CP Confirm the settings in the dialog with OK. Following save and compile the hardware configuration of the SIMATIC S7-300 station and download it in the CPU. Figure 3-6 button Configure Network Open the program NetPro. Therefore you have to click the button Configure Network in the toolbar. Figure 3-7 program NetPro Select the CPU of the SIMATIC S7-300 station. Now insert an ISO-on-TCP connction with the menu command Insert New Connection. V /19

11 Figure 3-8 dialog Insert New Connection In the dialog Insert New Connection select the connection type ISO-on- TCP connection and the connection partner unspecified. Click the button Apply to open the property view of the ISO-on-TCP connection. V /19

12 Figure 3-9 property view of the ISO-on-TCP connection register General Information In the property view of the ISO-on-TCP connection you have to change to the register General Information. Here you don t select the function Active connection establishment, because the connection is build up actively build up from the PC station. V /19

13 Figure 3-10 property view of the ISO-on-TCP connection register Addresses In the property view of the ISO-on-TCP connection you have to change to the register Addresses. Here you set the IP address of the communication peer, in the example that s the IP address of the PC station Above all enter the local and remote TSAP. In the example local and remote the same TSAP is used: AAAAAAAA. Confirm the settings in the dialog with OK. So you come back to the dialog Insert New Connection. Confirm the dialog Insert New Connection with Close. In NetPro save and compile the configuration of the SIMATIC S7 station. Following download the configuration of the SIMATIC S7 station in the CPU. So you download the configuration of the connection in the CPU. The configuration of the connection is finished. In the S7 program you have to call the communication blocks FC5 AG_SEND and FC6 AG_RCV from the SIMATIC_NET_CP Library CP 300. NOTE If you use a SIMATIC S7-400 station you will have to call the communication blocks FC50 AG_LSEND and FC60 AG_LRCV from the SIMATIC_NET_CP Library CP 400. At this follow the instructions in chapter 4 Description of the S7 program : V /19

14 4 Description of the S7 program In the SIMATIC Manager you have to open the STEP 7 project that contains the configuration of the SIMATIC S7-300 station with the menu command File Open. Furthermore you have to open the SIMATIC_NET_CP Library with the menu command File Open Libraries. Figure 4-1 opening the SIMATIC_NET_CP Library You find the communication blocks FC5 AG_SEND and FC6 AG_RCV in the SIMATIC_NET_CP Library under CP 300 blocks. Figure 4-2 SIMATIC_NET_CP Library Copy the communication blocks FC5 AG_SEND and FC6 AG_RCV in the folder Blocks of the S7 program. The communication blocks FC5 AG_SEND and FC6 AG_RCV must be called permanently in the OB1 cycle. V /19

NetPro. Right-click one of the input parameter and select the menu command Connections.

15 Figure 4-3 calling the FC5 AG_SEND The values of the input parameters ID and LADDR of the FC5 AG_SEND and FC6 AG_RCV respectively are defined with the configuration of the connection in NetPro. Right-click one of the input parameter and select the menu command Connections. Figure 4-4 selecting the menu command Connection The following dialog will opened: V /19

16 Figure 4-5 selecting the configured ISO-on-TCP connection In the dialog you see the ISO-on-TCP connection, which is configured in NetPro. Select this ISO-on-TCP connection and confirm the dialog with OK. The values of the input parameter ID and LADDR of the FC5 AG_SEND and FC6 AG_RCV respectively are entered automatically. A second possibility is that you find out the function parameters ID and LADDR from the property view of the ISO-on-TCP connection which is configured in NetPro. Figure 4-6 property view of the ISO-on-TCP connection Enter the remaining input and output parameters of the FC5 AG_SEND and FC6 AG_RCV. V /19

17 Here you can find a sample program calling the FC5/6. Figure 4-7 sample program FC5 AG_SEND and FC6 AG_RCV Save the created S7 program and download it in the S7 station. V /19

18 5 Basic configuration instructions 5.1 TSAP rules The TSAP length should always be 8 characters. The characters permitted for TSAPs are letters, numbers, hyphens and underscores. You should use only uper case letters. The local and remote TSAP can bet he same. The TSAP must be unique for each connection. To check the TSAPs you should use the output of the character string in hexadecimal format. 5.2 Rules for connection establishment A connection is established actively only by one station. The partner station must then establish the connection passively. The type of connection establishment has no influence on the jobs. V /19
