Switch Settings
Node address
Two rotary switches on the front of the PROFIBUS-DP Gateway Unit are
marked Address x10 and x1. These rotary switches are used to set the
PROFIBUS-DP node address of the Unit. Addresses in the range of 00
through 99 are valid. Be sure the node address on the Unit is equal to the sta-
tion address in the master’s configuration.
The node address is used to identify individual nodes on the PROFIBUS-DP
network, the node address must be unique for each unit. Selecting a non-
unique address for a unit will prevent the PROFIBUS-DP network from start-
ing or operating correctly.

1.
Turn OFF the power supply before setting the node address.
2.
Set the switch to the (new) node 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.
Note
Always turn OFF the power to the Unit before changing the node address set-
ting. The Unit only reads the mode address setting during the initialization fol-
lowing a power-up, i.e. any changes after power up will have no effect.
Baud rate setting
In order to select the baud rate used for communication over the Host Link/
Compoway-F interface, two switches are available. Baud rate switches are
ERR
(unit error)
Red
Not lit
The PROFIBUS-DP Gateway Unit is in normal operation, in case the
RUN LED is lit.
Blink
The Unit was not able to initialize normally due to a fatal error during
system startup.
Lit
Fatal error during operation occurred.
FCOM
(Host Link / Compoway-F
communication)
Green
Not lit
No communication with all Host Link/Compoway-F devices. This may
be due to a communication failure (broken wire), a non initialized
PROFIBUS-DP interface or the PROFIBUS-DP Gateway Unit is not
exchanging data with all configured R88A-MCW151-E or Temperature
Controllers.
Blink
Compoway-F communication is performed through the auxiliary port.
The PROFIBUS-DP interface is bypassed.
Lit
Host Link/Compoway-F communication active, no errors.
FERR
(Host Link / Compoway-F
error)
Green
Not lit
No Host Link/Compoway-F errors present. The PROFIBUS-DP Gate-
way Unit is exchanging data with all configured R88A-MCW151-E or
Temperature Controllers.
Lit
A Host Link/Compoway-F communication failure occurred.
COMM
(PROFIBUS communica-
tion)
Green
Not lit
The PROFIBUS-DP Gateway Unit is not in Data_Exchange with the
PROFIBUS-DP master.
Blink
Auxiliary port ready, PROFIBUS-DP interface is not active.
Lit
The PROFIBUS-DP Gateway Unit is in Data_Exchange with the
PROFIBUS-DP master.
BF
(Bus fail)
Green
Not lit
No PROFIBUS-DP communication errors, Set_Prm and Chk_Cfg mes-
sages have been accepted. Data_Exchange in progress.
Blink
Either the Set_Prm or the Chk_Cfg message has been rejected by the
PROFIBUS-DP Gateway Unit. The Unit is not in Data Exchange with
the PROFIBUS-DP master.
Lit
All communication with the PROFIBUS-DP master is lost. The PROFI-
BUS-DP Gateway Unit is awaiting a new Set_Prm message.
