An example is given using the following configuration:
You must adjust the communication parameters and possibly the switch settings
(addresses) of the bus nodes.
Procedure
To set a new configuration, first press the Define global data softkey. The fol-
lowing description of how to proceed is based on the assumption that you are
SIMATIC S7,
already familiar with this menu.

1. Set up a new project and CPU programs with the STEP7 tool. You must set
2. Network MPI nodes, i.e. network CPU programs with MPI address.
3. Call "Global data" menu (via File manager / MPI network / Options /
4. Compile this configuration. A new SDB is generated for each CPU program.
5. Set the cyclical transmit pattern. Once the configuration has been compiled
6. Compile your configuration again.
7. Transfer the SDB (from the CPU program of the PLC) to the PLC.
8. Call FB1, DB7 must be parameterized for all operator control components
9. The status pointer (double word) must be configured in FB1 for each compo-
