    04/99 Configuring Event Messages Configuring Event Messages In the previous steps you could test the functioning of your system. What you still need is information on the current operation of your system - the so-called event messages. For example, you want a message to be displayed on the OP when you switch the system on.
  • Page 44 Configuring Event Messages 04/99 In the status line (not shown in the figure), you will see the relevant address which connects the message to the PLC. In your example, for message no. 001 the address is System ON: DB 46 DBX 5.0. Generating the control program To allow the exchange of data between the C7-CPU and C7-OP you must still adjust your control pro- gram and reload it into the C7.

  • Page 47: Symbolic Addressing

    04/99 Symbolic Addressing Symbolic Addressing When programming with STEP 7 you work with operands such as I/O signals, bit memories, counters, timers, data blocks and function blocks. So far you have addressed these operands in your program absolutely (e.g. on DB46). However, it is helpful to assign symbolic names for them (e.g. on DB_OP, Belt control).

  • Page 48: Setting Symbolic Representation

    Symbolic Addressing 04/99 Setting symbolic representation To also display the symbolic names in your program, you must set the appropriate type of representation. In the offline data management, open the function FC1. In the LAD/STL/FBD Editor which appears, select the menu item View → Display → Symbolic Representation . The absolute addresses are replaced by the symbolic names.
