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.
Group Assignment
If the slave supports sync/freeze functionality, it can be assigned to the masters sync/freeze
groups by clicking on the checkboxes. The sync/freeze assignment of the groups is also
displayed (these can be changed via the master properties dialog).
Parameter Assignment
A slaves user-specific parameters can be changed via the
parameter assignment
page. User-
specific parameters for a slave device are defined in the corresponding GSD file for the
device, the definition of which are device-specific and should be found in the documentation
for the device.
Parameters can be altered via combo boxes or via direct input of hexadecimal values. The
hexadecimal values for the user_prm_data are displayed at the bottom of the screen and can
be edited directly (consult the device specific documentation for the meaning of these
values).
Adding I/O to a Slave
The possible I/O combinations for a given slave may be fixed or configurable (i.e. modular)
depending on the GSD file for the device. When the I/O configuration is fixed, the fixed I/O
are always defined whenever the device is added to the network. However, for modular
devices, the I/O configuration must be assigned manually.
