5.4 Setting the PROFIBUS address
The CIM 150 PROFIBUS module has two hexadecimal rotary
switches for setting the PROFIBUS address. The two switches
are used for setting the four most significant bits, SW3, and the
four least significant bits, SW4, respectively. See fig. 10.
Fig. 10 Setting the PROFIBUS address
The table below shows examples of PROFIBUS address settings.
A restart of CIM/CIU 150 has to be performed for a PROFIBUS
address change to take effect.
For a complete overview of the PROFIBUS addresses, see
section 10. PROFIBUS address.
5.5 Termination resistors
The termination resistors are fitted on the CIM 150 PROFIBUS
module. See fig. 11.
Fig. 11 Internal termination resistors
CIM 150 has a DIP switch with two switches, SW1 and SW2, for
cutting the termination resistors in and out. Fig. 12 shows the DIP
switches in cut-out state.

5.6 Status LEDs
CIM 150 PROFIBUS has two LEDs. See fig. 8.
• Red and green status LED, LED1, for PROFIBUS
communication.
• Red and green status LED, LED2, for GENIbus
communication between CIM/CIU 150 and the connected
Grundfos product.

LED2
5.7 Communication watchdog
The state of the PROFIBUS communication watchdog can be
changed with a PROFIBUS commissioning tool, for example
Siemens Simatic Manager. If the watchdog is enabled, all bits in
the ControlModule are automatically set to "0" if the PROFIBUS
communication is broken. See section 7.2 Control module
(ControlModule, module 2).
As a result, the booster system will be set to local mode and then
be operating according to the local operating mode, local setpoint
and local control mode.
5.8 Reaction to PLC "Stop button"
If the PLC is stopped by the operator, all output registers will be
set to "0".
As a result, the control bit RemoteAccessReq will be cleared, and
the booster system will be set to local mode and then be
operating according to the local operating mode, local setpoint
and local control mode.
TM04 1702 0908
You must set the PROFIBUS address decimally from
1 to 126. The address 126 is normally used for
special purposes and should not be used.

To ensure a stable and reliable communication, it is
important that only the termination resistors of the
first and last units in the PROFIBUS network are cut
in.
Status Description
Off. CIM 150 has been switched off.
Permanently green.
CIM 150 is ready for PROFIBUS data
transmission (Data Exchange State).
Permanently red.
CIM 150 does not support the connected
Grundfos product.
Flashing red.
Wrong or missing PROFIBUS
configuration or no contact to the
PROFIBUS master.
Status Description
Off. CIM 150 is switched off.
Permanently green.
GENIbus communication between CIM
150 and the Grundfos product is OK.
Permanently red.
CIM 150 does not support the connected
Grundfos product.
Flashing red.
No GENIbus communication between CIM
150 and the Grundfos product.
During startup, there may be a delay of up to 5
seconds before the LED2 status is updated.
