The Edit Slave dialog box allows you to perform the following tasks:
•
The Search Slave button allows you to go to and edit other slave
addresses without going back to the Profibus-DP I/O dialog box.
•
The Next Slave button allows you to go to and edit the next
slave address in numerical increasing order without going back
to the Profibus-DP I/O dialog box.
•
The Prev Slave button allows you to go to and edit the previous
slave address in numerical decreasing order without going back
to the Profibus-DP I/O dialog box.
•
The Edit I/O Addr button allows you to change or program a
slave's module's I/O address.
•
The X<->WX button toggles the image register type for the
selected module between discrete and word inputs. To ensure
that discrete are toggled to words, the discrete must be on a 16-
bit boundary.
•
The Y<->WY button toggles the image register type for the
selected module between discrete and word outputs. To ensure
that discrete are toggled to words, the discrete must be on a 16-
bit boundary.
•
The Unify button moves all modules for the selected slave into
the first module. Unification is only allowed if all modules are
either discrete or words. Only the first address is retained.
•
The Compact button moves all discrete image register types to
word image register types for every module of the selected
slave. It then unifies all the modules into the first module. To
ensure that discrete are toggled to words, the discrete must be on
a 16-bit boundary. Only the first address is retained.
•
The Restore button restores modules for the selected slave
according to the COM PROFIBUS configuration, including the
image register types. Zero addresses are assumed for all but the
first address, which is kept.
Before entering your I/O configuration, be aware of the following
