Device configuration comprises the following steps:
- Station address assignment.
- Slave module configuration.
Mapping of the slaves' I/O data to the Unit's buffer areas.
-
Setting the slaves' User Parameter Data.
-
The configurator offers the option to automatically assign the I/O data of each
slave to a location in the Unit's buffer areas. This feature is turned ON by
default, and can be turned OFF via the menu item 'Settings – Master
Configuration' (select the Master Unit first), or by double-clicking the Master
Unit.
Station addresses will be assigned automatically according to sequence of
entry. Any automatically assigned address can be changed manually in the
Slave Configuration panel.
To configure a slave, select 'Settings – Slave Configuration', or double-click
on its icon in the PROFIBUS-DP window to bring up the following dialog box:
The station address can be changed by typing over the existing one, and
each slave can be assigned a symbolic name in the 'Description' field..
The check-box 'Activate device...' can be unchecked if the slave is not yet
available in the network, but address space needs to be reserved to add it
later.
When the 'Enable watchdog control' item is checked, the slave will perform a
specific action when bus communication is disrupted (depends on available
functionality in the slave, e.g. output hold, output clear). The actual watchdog
time is specified in the bus parameters. It is recommended to keep this
function enabled.
