2. Introduction
2.1 About this functional profile
This functional profile describes the following protocols for the
Grundfos DDD system (Demand Driven Distribution CU 354):
• CIM 150 PROFIBUS DP
• CIM 500 Ethernet for PROFINET IO.
The data in this document are subject to change without prior
notice. Grundfos cannot be held responsible for any problems
caused directly or indirectly by using information in this functional
profile.
2.2 PROFIBUS DP-V0
The PROFIBUS DP interface conforms to the PROFIBUS DP-V0
standard for cyclic data transmission.
The option of setting the PROFIBUS DP address via bus is not
supported as the CIM 150 has two switches for setting the
address.
2.3 PROFIBUS DP-V1
Only the diagnostic part and the extra three bytes of
parameterisation data are supported. Acyclic data transmission is
not supported.
2.4 Assumptions
This functional profile assumes that the reader is familiar with
commissioning and programming of PROFIBUS and PROFINET
devices.

3. System description
The system diagrams give an overview for the different
technologies of how to connect the CIM to the Grundfos DDD
system that is to be connected to a PROFIBUS/PROFINET
network.
The DDD system controls and monitors a number of pumps,
all connected with RS-485 cables (Sub-GENIbus).
CIM
The CIM solution is an add-on communication module that is to
be fitted into the back of the CU 354, using a 10-pin connection.
The DDD system will supply power to the CIM module. See fig. 1
and fig. 3.

5. PROFIBUS DP, CIM 150 setup
5.1 PROFIBUS bus topology
The PROFIBUS-preferred bus topology is daisy chaining as
illustrated in fig. 3. The end devices of a physical bus segment
must be terminated (LT = Line Termination). Each device must
have a unique physical address [1-126]. Up to 32 PROFIBUS
devices can be connected to a bus segment, and by using a
repeater another 32 devices can be connected. This can be
repeated until the maximum number of addresses are used.
Make sure that each device is connected to a proper earth
potential.

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. 6.
Fig. 6 Setting the PROFIBUS address
The table below shows examples of PROFIBUS address settings.
A restart of the CIM 150 has to be performed for a PROFIBUS
address change to take effect.
For 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. 7.
Fig. 7 Internal termination resistors
The CIM 150 has a DIP switch with two switches (SW1 and SW2)
for cutting the termination resistors in and out. Figure 8shows the
DIP switches in cut-out state.

5.6 Status LEDs
The CIM 150 PROFIBUS module has two LEDs. See fig. 4.
• Red/green status LED (LED1) for PROFIBUS communication.
• Red/green status LED (LED2) for GENIbus communication
between the CIM 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, e.g. Siemens
Simatic Manager. If the watchdog is enabled, all bits in the
ControlModule (see section 7.2 Control module (ControlModule,
module 1)) are automatically set to "0" if the PROFIBUS
communication is broken.
As a result, the DDD 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 DDD 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

6. PROFINET IO, CIM 500 setup
6.1 Connecting the Ethernet cable
RJ45 plugs and Ethernet cable must be used. The cable shield
must be connected to protective earth at both ends.
The CIM 500 is designed for flexible network installation.
The built-in two-port switch makes it possible to daisy chain from
product to product without the need of additional Ethernet
switches. The last product in the chain is only connected to one of
the Ethernet ports. Each Ethernet port has its own MAC address.
Fig. 9 Example of Industrial Ethernet network
Fig. 10 Example of Ethernet connection (CIM 500)
6.2 Setting the Industrial Ethernet protocol
The CIM 500 Ethernet module has a rotary switch for selection of
the Industrial Ethernet protocol. See fig. 11.
Fig. 11 Selecting the Industrial Ethernet protocol
6.3 Setting up IP addresses
The CIM 500 Ethernet module is default set up to a fixed IP
address. It is possible to change the IP address settings from the
built-in web server.
Warning
The CIM 500 must only be connected to SELV or
SELV-E circuits.
Note
It is important to connect the cable shield to
earth through an earth clamp or to connect the
cable shield to earth in the connector.

cable.
• Configure the PC Ethernet port to the same subnetwork as the
CIM 500, e.g. 192.168.1.101, and the subnet mask to
255.255.255.0. See section A.2 Web server configuration on

7. Detailed description of data modules
7.1 Data types
The Grundfos CIM 150/500 supports the following data types.
All data types, except for data type 10, comply with the data types
according to specification standard IEC 61158-6 for use in
PROFIBUS/PROFINET profiles.
All multi-byte data types are transmitted with MSB
(Most Significant Byte) first.
7.2 Control module (ControlModule, module 1)
The control module is a PROFIBUS/PROFINET output module
used for the control of the DDD system from the bus. Its data type
is 10, non-standard.
7.2.1 Explanation to event trigger
Rising edge
Control bits with a rising-edge event trigger behave like a
command that is executed when a bit transition from "0" to "1"
occurs. Each of them has a corresponding acknowledge bit in the
StatusModule which is set when the command is executed and
cleared when the control bit is written back to "0".
State
Control bits with a state event trigger behave like a "state" that is
forced upon the DDD system. In the CIM 150/500, the "actual
state" of the DDD system as read from the StatusModule is
continuously compared with the "requested" state in the
ControlModule, and the CIM 150/500 writes the appropriate
GENIbus command to the DDD system to make the two states
correspond to each other. Due to state restrictions or priorities,
this might not always be possible (see explanation to the bit in
question).
Value change
Control bits/bytes with a change event trigger behave like a
command that is executed when the bit/byte changes its value.
The CIM 150/500 will attempt to make the system operate
according to the requested value. The change will be reflected in
a bit/byte value in a corresponding input module.
7.2.2 Explanation to control bits
RemoteAccessReq
Control bit for setting the DDD system in remote mode (controlled
from the bus) or local mode (controlled from the CU 354):
However, certain commands from other control sources (e.g. Stop
or Max. from a local source or external Stop from a digital input)
have higher priority and will overrule the control from the bus.
OnOff
Control bit used to start and stop the DDD system:
ResetFault
Control bit that resets alarms and warnings.
CopyToLocal
If this bit is set, the remote setting of control mode, operating
mode and setpoint will be copied to the local setting during a
remote-to-local transition.
