3 1 Contents of this document This document shows you how to gain an overview over the operating mode of the automation system. Additionally, the instruction leads you step by step to the main information. As an example a CPU-317 was employed as master and an ET 200M as slave in the STEP 7 project. Other used modules can be treated in the same way. Note The order and procedure of the subsequent actions is not mandatory, but it is useful for most standard cases. Note Save the current content of the diagnostic buffer before performing further actions at the CPU such as RESET or RUN-STOP switchovers. The saved events support you in the analysis and can also contribute towards finding solutions when queried by the Technical Support. Page 3/14

4 2 Recording Plant Status and Event Entries 2.1 Display plant status No. Instruction Note / Explanation 1 In the SIMATIC Manager you select the desired PC station. 2 Click Online in the toolbar. 3 Double-click the Hardware icon. In the window of the HW Config station you see the slave and its modules with the current status (marked with red boxes). The status icon marks those modules which currently provide diagnostic information. Figure 2-1 Page 4/14

5 2.2 Reading and saving the event entries of the CPU Continuing with display and saving of the event entries No. Instruction Note / Explanation 4 Double-click the CPU in HW Config SIMATIC 300 (1) Online. 5 Select the Diagnostic Buffer tab. 6 Click the Save as button in order to save the event entries of the diagnostic buffer. The content of the diagnostic buffer is now available to you in a txt-file. Figure 2-2 Note If you have marked a CPU in a offline window, you can use <CTRL><D> or the menu (PLC, Diagnostic/Setting, Module Information) to enter the Module Information windows without going online first.

6 Information on the diagnostic buffer The diagnostic buffer integrated in the CPU saves all occurring events. Due to the listed events, a detailed statement can be made in case of problems or failure. The diagnostic buffer of the CPU works as a ring buffer. The number of messages to be saved is fixed for the S7-300 CPUs. In the in the Diagnostic Buffer tab of the Module Information window (online) under Settings.. the number of displayed events can be specified. Note Further information for evaluating the diagnostic messages are available in chapter 23 of the Programming with STEP 7 manual. Page 6/14

7 3 Recording of Module Data and Diagnostic Data The term module data comprises entries such as order number, hardware version and firmware version of a module. 3.1 Reading the CPU module data No. Instruction Note 1 In the SIMATIC Manager you select the desired PC station. 2 Click Online in the toolbar. 3 Double-click the Hardware icon. 4 Click the module from which you request the module data. 5 Use the shortcut Strg + D or select Module Information... in the PLC -> Module information pull-down menu, to start reading out the module status. Figure 3-1 The displayed module data are directly read out (marked with a red box). Page 7/14

8 3.2 Reading out the DP Slave module data No. Instruction Note / Explanation 1 In the SIMATIC Manager you select the desired PC station. 2 Go online by clicking the Online button on the toolbar. 3 Double-click the Hardware icon in the right section of the Online window to obtain an overview over the status of the SIMATIC station. 4 Double-click the DP-Slave to open the Module Information... window. Figure 3-2 In the General tab of the Module Information... window the module data is displayed (marked with the red box). The displayed data are online data which were directly read out from the module. Page 8/14

9 3.3 Reading out the DP Slave diagnostic messages Continuing with reading out the DP Slave diagnostic messages No. Instruction Note / Explanation 5 Now select the DP-Slave Diagnostics tab in the Module Information IM window. 6 Click the Hex Format button to have the message displayed in Hex code. This hex-format shows you the diagnostic data record DS0 / DS1. Figure 3-3 In the DP Slave Diagnostics tab of the Module Information... window the Standard diagnostics of the slave box shows you the pending messages. In the bottom section the messages are represented divided in Slot, Channel number., and the Error message text. The Diagnostic in Hexadecimal Format window shows you the entire diagnostic data record DS0 / DS1 (marked with a red box). The HEX entries in the Diagnostic in Hexadecimal Format window of the DP slave station are dependent of the installed modules in the station. Note The ET 200M station was selected as an example. In the manual of ET 200M in chapter 9.3 you find the respective information which helps in detail for the analysis of the data records DS0 / DS1. Page 9/14

10 4 Display CPU Information with the Internet Browser In order to gain access to the CPU with the internet browser the following settings are necessary. On the PC side the IP address must be given for the internet protocol (TCP/IP) of the network card. The subnet mask is automatically activated after the input of the IP address. On the SIMATIC side the IP address must be given for the PN/IO interface of the CPU. Here the subnet mask is also automatically activated after the input of the IP address. The following section describes in detail how to make the required settings. In the following example, the point to point connection between the SIMATIC and the PC network card was made by means of a crossover LAN cable. WARNING The IP addresses of CPU and network card were selected as an example. When using an existing LAN network, you must check the IP addresses of your LAN stations with the network administrator.

11 4.1 Settings on the PC side No. Instruction 1 Go to the network connections of your PC. 2 Select the network connection and call up the Properties of the network connection via the right mouse button. 3 Now you select the Internet Protocol (TCP/IP) and click on the Properties button of Internet Protocol (TCP/IP). 4 Activate the Use the following IP address field and specify the IP address of the PC network card. When exiting the input field IP address: the value for the subnet mask will automatically be entered. 5 Complete the input via the OK button and Close. Figure 4-1 Note This IP address of the CPU was selected as an example. Ensure that the IP address of CPU and network card lie in the same number band xxx Page 11/14

12 4.2 Settings on the SIMATIC side No. Instruction 1 Double-click the hardware icon to open HW Config. 2 In the module rack you select the PN-IO interface. Use the right mouse button to open the selection menu. Click Object Properties. 3 Click the Properties button of the interface of type: Ethernet. 4 In Properties Ethernet Interface PN/IO you enter the IP address of the CPU. 5 Via the OK button you terminate the input mode for the PN/IO interface. 6 Compile the HW Config and transfer it to the CPU. Figure 4-2 Page 12/14

13 4.3 Access with the internet browser No. Instruction Note / Explanation 1 In the address field of the browser you enter the TCP/IP address of the CPU and complete the input by pressing ENTER. 2 Pressing ENTER takes you to the start page with the CPU information data. The browser displays the WELCOME page of the CPU. Figure 4-3 Page 13/14

14 4.4 Browser window with access options to the CPU information data Figure 4-4 Selection menu for the CPU information data (marked with a red box).
