slave I/O configuration list). The above example shows a slave device being added to the
network at node address 7.
Slave Address
To change the node address of a slave already configured on the network, locate the slave in
the network listview and drag it to the position in the list corresponding to the desired
address. Alternately, the slave address can be modified from the module properties page (see
below).
Module Properties (Slave)
To display the properties of a given slave, right click the required slave in the busview and
choose properties (or double click the icon in the busview). Under the general tab, various
details (including GSD file details) relating to the selected slave device are displayed. Several
configurable options are also available (see below).
Profibus Address
The actual profibus address of the selected slave is shown in the address selection box. Only
available addresses are listed and can be selected as new address.
Watchdog
According to the profibus specification, a slave device may be configured with a watchdog
function such that the master must poll the slave within a defined interval. If this feature is
enabled and the master fails, the slaves watchdog timer will timeout and the slave will reset
itself.
