4.3.3 RS485 Interface configuration
Fig. 4.9 Interface configuration
The type of the interface (RS485), the number of the assigned slot and the mode (master
/ slave) are displayed in the tree.
To establish the connection over the interface, it has to be configured. The parameters of
the interface are displayed in the right part of the window. The default value depends on
the target device. The parameters Protocol and Interval between requests are only in
the master mode available. In the slave mode they are inactive and grayed out.
The icon As standard is used to save the settings as default values for future pro-
jects.
The icon Factory settings is used to apply the unchangeable factory settings.
The button Read is used to read out the current settings from the connected device.
Use the button Close to save the settings in the project and close the dialog.
4.3.3.1 Master mode
Each interface can control up to 16 slaves. Each slave supports up to 256 variables. The
addresses and names of the variables need only be unique if they belong to the same
slave.
In the master mode, all slaves connected to the interface are sequentially requested. Se-
lect the mode Master in the parameter list, set other connection parameters and add the
required number of slaves using the item Add slave in the interface context menu.
