Switch Settings
Node address
Two rotary switches on the front of the PRT1-SCU11, marked Address x10
and x1, are provided to set the PROFIBUS DP device address of the Unit. The
address can be set in the range of 00 through 99. The device address on the
Unit must be the same as the address used in the master’s configuration.
The device address is used to identify individual slave devices on the PROFI-
BUS DP network. The device address must be unique for each unit. Selecting
a non-unique address for a unit will prevent the PROFIBUS DP network from
starting or operating correctly.
In order to set the device address, perform the following steps.
1,2,3...
1.
Turn OFF the power supply before setting the device address.
2.
Set the switch to the (new) device address. Use a small screwdriver to
make the setting, taking care not to damage the rotary switch. The node
address is factory-set to 0.
3.
Turn ON the power again.

Color
Status
Description
RUN
Green
Not lit
• Startup test failed, Unit not operational.
• Operation stopped due to a fatal error.
• Power is off.
Lit
Initialization successful, Unit is in normal operation.
ERR
(unit error)
Red
Not lit
The PRT1-SCU11 is in normal operation (RUN LED is lit).
Flashing
The Unit was not able to initialize normally due to a fatal error during
system startup.
Lit
Fatal error during operation occurred.
FCOM
(RS-422A / RS-485
communication)
Green
Not lit
No communication with any devices attached to the RS-422A / RS-485
network. This may be caused by:
• a communication failure (broken wire).
• a non initialized PROFIBUS DP interface.
• the PRT1-SCU11 is not able to exchange data with all configured
devices.
Flashing
Communication with the RS-422A / RS-485 network is performed
through the auxiliary port. The PROFIBUS DP interface is bypassed.
Lit
RS-422A / RS-485 communication active, no errors.
FERR
(RS-422A / RS-485
communication)
Green
Not lit
No RS-422A / RS-485 network errors present. The PRT1-SCU11 is
exchanging data with all configured devices.
Lit
A failure occurred in the RS-422A / RS-485 network communication.
COMM
(PROFIBUS communica-
tion)
Green
Not lit
The PRT1-SCU11 is not in Data_Exchange with the PROFIBUS DP
master.
Flashing
Auxiliary port ready, PROFIBUS DP interface is not active.
Lit
The PRT1-SCU11 is in Data_Exchange with the PROFIBUS DP mas-
ter.
BF
(PROFIBUS Bus fail)
Green
Not lit
No PROFIBUS DP communication errors, Set_Prm and Chk_Cfg mes-
sages have been accepted. Data_Exchange in progress.
Flashing
Either the Set_Prm or the Chk_Cfg message has been rejected by the
PRT1-SCU11. The Unit is not in Data Exchange with the PROFIBUS
DP master.
Lit
All communication with the PROFIBUS DP master is lost. The PRT1-
SCU11 is awaiting a new Set_Prm message.
