The GSD file for your HPG generator is available on the user manual CD that
came with your unit. You can also download the GSD file from
www.dressler.com.
Setting the Unit’s PROFIBUS Network Address
Use the rotary address switches next to the PROFIBUS port on the rear panel
to set the HPG generator's address. Allowable addresses are numbers
between 0 and 126, selected in hex format.
To enter the unit's address, set the switch positions for hex representation.
The following example demonstrates switch settings for an address of12:
0 C = 0x0Ch = 12.
Note: The unit’s address can only be changed from the PROFIBUS master if
the hardware address is above 126.
PROFIBUS Termination
Please ensure that you follow proper termination procedures if your HPG
generator is the last slave on the
PROFIBUS cable. The termination resistors
should be on the connector housing of the PROFIBUS cable (not included).
PROFIBUS Baud Rate
The auto-baud feature of Dressler’s certified PROFIBUS interface adjusts
automatically to the rate of the PROFIBUS master system. Baud rates are
available in discrete steps from 9600 bits (9.6 kbits) to 12 Mbits. The auto-
baud feature operates much like a modem or FAX machine in that, at startup,
there is a small delay while the interface
traverses the different baud rates and
then locks in. Please ensure that your PROFIBUS master allows for this delay.
PROFIBUS Status LEDs
The PROFIBUS LEDs (light-emitting diodes) on the rear panel consist of two
status LEDs to indicate whether the PROFIBUS system is operating properly.
See
Figure 4-20 .
Figure 4-5 describes the LED states and associated PROFIBUS status.
