2.4 System diagram
Figures CIM solution for Hydro Multi-B and Solution with CIM 300 and 500 for CU 352 and CIU for Hydro Multi-E (CU 351) give an overview of
how to connect the module or unit to the Grundfos booster system that is to be connected to a BACnet network.
The Hydro MPC, Control MPC and Multi-E boosters are available in two variants. They have different CIM/CIU connections as described
below.
CIM solution
A Communication Interface Module (CIM) is an add-on communication module that you fit into the following products:
• CU 352 MPC
• CU 323 Multi-B
• Multi-E based on MGE motors model H or later
• TPED twin-head pump in multipump mode
• MAGNA3-D twin-head pump in multipump mode.
In this setup, the booster system supplies power to the module. See figure CIM solution for Hydro Multi-B below.
CIU solution
A Communication Interface Unit (CUI) is a box incorporating a power supply module and a CIM 300 BACnet module. It can either be mounted
on a DIN rail or on a wall. See figure Solution with CIM 300 and 500 for CU 352 and CIU for Hydro Multi-E (CU 351).
The unit is used with the following products:
• CU 351 MPC
• Multi-E based on MGE motors before model H.
The Hydro MPC with the CU 351 or the Hydro Multi-E controls and monitors a number of pumps (2 to 6), all connected with RS-485 cables. If
fitted with an extra GENIbus module, the Hydro MPC with the CU 351 can be connected to the unit via an RS-485 cable.
The CU 351 must have an external GENIbus module installed in order to communicate with the CIU BACnet unit.

master directly to the BACnet MS/TP network.

Pos. Description
M Master
S Slave
LT Line Termination
BR Bias Resistors
The BACnet MS/TP is a multi-master system which means that
there can be more than one master on the network. It uses a token
to control access to the bus network. A master node may initiate the
transmission of a data telegram when it holds the token. Both
master and slave nodes may transmit data telegrams in response to
requests from master nodes, but slaves never hold the token.
Master nodes pass the token between them.
A BACnet MS/TP segment is a single contiguous medium to which
BACnet nodes are attached. Segments can be connected by use of
repeaters or bridges, thus forming networks.
Multiple networks may be interconnected by BACnet routers to form
a BACnet inter-network.
3.1.1 Line termination resistors
Line termination must be connected at each of the two ends of the
segment medium. The CIM/CIU 300 has optional line termination
resistor on board.
3.1.2 Bias resistors
At least one set, and no more than two sets, of network bias
resistors must exist for each segment so that an undriven
communications line is held in a guaranteed logical one state. The
bias provides a reliable way for stations to detect the presence or
absence of signals on the line. An unbiased line takes an
indeterminate state in the absence of any driving node.
The CIM/CIU 300 has no bias resistors.

Ground Grey Ground
The ANSI/ASHRAE BACnet standard states that the cable screen
must only be earthed at one end of the segment to prevent earth
fault currents.
3.4 Setting the BACnet transmission speed
Set the transmission speed correctly before the CIM 300 is ready to
communicate on the BACnet MS/TP network. Use the DIP switches
SW4 and SW5 to set the transmission speed.
The default transmission speed is 9600 bit/s, but we recommend
higher speeds for better data throughput. All devices on the BACnet
MS/TP network must communicate at the same transmission
speed.
SW4 SW5
TM041710
BACnet transmission speed settings
3.4.1 DIP switch settings
Available transmission speeds in bit/s: 9600, 19200, 38400 and
76800.
Use the DIP switches SW4 and SW5 to select the desired speed.
Transmission speed
[bit/s] SW4 SW5
9600 OFF OFF
19200 OFF ON
38400 ON OFF
76800 ON ON
The default transmission speed is 9600 bit/s, as per the BACnet
MS/TP standard. The transmission speed is effective immediately
after setting the values of the DIP switch.
3.5 Selecting the Device Object Instance Number
The Device Object Identifier value consists of two components:
• a 10-bit Object Type (bits 22 to 31)
• a 22-bit Instance Number (bits 0 to 21).
31 22
10 bits 22 bits
21 0
Object type Instance Number
...
TM045977
Bit numbers
The Object Type is fixed and determines that it is a Device Object.
The Instance Number is a numeric code that is used to identify the
device. It must be unique inter-network-wide, that is, on all
interconnected networks.
The CIM 300 offers two different approaches to setting the BACnet
Device Object Instance Number: default and custom, both
described in the following subsections.
3.5.1 Default Instance Number
By default, the CIM 300 uses a pre-defined Device Object Instance
Number which is 227XXX where XXX is the BACnet MAC address.
This gives an Instance Number range of 227000 to 227127.
Example
The BACnet MAC address is set to 20 via the hexadecimal rotary
switches, so the Device Object Instance Number is 227020.
Related information
3.7 Selecting the BACnet MAC address
3.5.2 Custom Instance Number
To use the complete Instance Number range, set the new Instance
Number with the BACnet object Custom Device Object Instance
Number (AV, 0), and set SW3 to ON. This immediately sets the new
Device Object Instance Number.
SW3
TM041709
Device Object Instance Number
Device Object Instance Number SW3
Default (227000 + BACnet MAC address) OFF
Custom, set with object (AV, 0) ON
The default Present_Value of the Custom Device Object Instance
Number is 231.
Example
The Present_Value of the Custom Device Object Instance Number
(AV, 0) is 231, so the Device Object Instance Number is 231.
The Present_Value of the Custom Device Object Instance
Number cannot be 4194303 as this is a reserved value.
10
English (GB)

3.6 Selecting the Device Object Name
The property Device_Name is a character string that must be
unique inter-network-wide. By default, the name is constructed as
"Grundfos - XXXXXX" where XXXXXX is the current Device Object
Instance Number as described in the section Selecting the Device
Object Instance Number.
Example
The Device Object Instance Number is 227001, so the Device
Object Name is "Grundfos - 227001".
If a new name is selected, it is stored in the device and replaces the
default naming scheme.
Related information
3.5 Selecting the Device Object Instance Number
3.7 Selecting the BACnet MAC address
To set the BACnet MAC address, use the two hexadecimal rotary
switches, SW6 and SW7.
The value must be within the range of 0 to 127. An illegal value
results in a MAC address of 0.
SW6 SW7
TM041706
Setting the BACnet MAC address
For a complete overview of BACnet addresses, see section BACnet
MAC address, CIM 300.
You must set the BACnet MAC address decimally from 0
to 127 and it must be unique on the BACnet MS/TP
segment.

3.8 Termination resistor
A termination resistor for line termination is fitted on the CIM 300
and has a value of 120 Ω. It is to be cut in if the CIM 300 is set as
the last station on the network.
The CIM 300 has two DIP switches, SW1 and SW2, for cutting the
termination resistor in and out.
SW1 SW2
TM041701

Default setting: The termination resistor is cut out.
3.9 Cable length
The recommended maximum cable length within a BACnet MS/TP
segment is 1200 metres (4000 ft) with 0.82 mm2 (AWG 18) cable.
The connection between the BACnet modules must be made by a
screened, twisted-pair cable with a characteristic impedance
between 100 and 130 Ω.
3.10 LEDs
The CIM 300 BACnet has two LEDs:
• red and green status LED (LED1) for BACnet MS/TP
communication
• red and green status LED (LED2) for internal communication
between the CIM 300 and the Grundfos pump.
3.10.1 LED1, BACnet MS/TP communication

5. Supported services
BACnet Interoperability Building Blocks (BIBBs) are collections of one or more BACnet services. These are described in terms of an "A" and a
"B" device. Both devices are nodes on a BACnet inter-network. In most cases, the "A" device acts as the user of data (client), and the "B"
device is the provider of this data (server).
The CIM/CIU 300 and 500 are BACnet Application-Specific Controllers (B-ASC) with a few additional services.
5.1 Data-sharing services
