52How to Create a New DP Master Project

When a model is selected and the <OK> button has been pressed, the

Slave Parameter

Settings

dialog appears.

Note:

Adding a slave changes the addresses of the I/O data in the buffer memory of the

master. It is therefore necessary to update the PLC program and (if used) the

autorefresh settings.

Duplicate Slave

The configuration of a modular DP slave like the ST1H-PB involves several steps like selecting

the modules and setting the module specific user parameters. If a PROFIBUS network includes

several slaves of the same type, this may require to repeat the same actions for each slave again.

To simplify the procedure it is possible to add an exact copy of an already existing slave to the

project again.

Select a slave and press the right mouse button to display the slave-specific context menu. This

menu contains the entry

Duplicate Slave

. Click on this menu item to get an additional slave with

the same configuration (selected modules, user parameters etc.) inserted into the PROFIBUS

network. This avoids inserting a new slave of the same type, selecting the modules again and

adjusting the parameter settings.

Note:

The new slave has identical settings compared to the original one. For this reason the

FDL address has to be adjusted and the slave name must be changed after duplicating

the slave.

Adding a slave changes the addresses of the I/O data in the buffer memory of the
