After the drop, WinDP assigns the address of the bus slave to the PLC output in the I/Q window. You can immediately see which PLC addresses are still available.
The busmaster is stopped during the loading process. A dialogue window appears with a prompt. Select "Yes" to execute the loading process. After the loading process is complete, the busmaster is restarted, again based on a prompt. After the MPS is read, all of the PLC input and output adresses of the slaves are recognised by the busmaster.
Loading of master parameter set
Before you make a connection to the busmaster, you must check and, if required, adjust the busmaster DIP switch positions. The busmaster coupling field is set by the DIP switch S4. After all PROFIBUS-DP slaves are configured, the information in the busmaster file must be transferred together with the bus parameters set in WinDP (baud rate, etc.) to the busmaster. To do this, select the menu item "File, Load". WinDP prepares the master parameter set MPS, containing all data needed for operation of the busmaster, slave and bus system PROFIBUS-DP and then transfers this information to the busmaster.
Address assignments
To be able to activate specific valves, it is necessary to allocate the bits of a PLC output to the individual valve positions on the valve block. If you have allocated a 12-position valve block to PLC addresses Q0 to Q2, the individual bits of these 3 bytes should be set up according to tables 4-1a and 4-1b.Now the UL/DIA LED on the valve block system's bus module must illuminate continuously and the BF LED should be off. The status display on the busmaster must extinguish (see the busmaster handbook).
