Pos. Description
M Master
S Slave
LT Line Termination
BR Bias Resistors
BACnet MS/TP is a multi-master system, meaning 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.
2.1.1 Line termination resistors
Line termination must be connected at each of the two ends of the
segment medium. CIM/CIU 300 has optional line termination
resistor on board.
2.1.2 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 will be 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 will take an
indeterminate state in the absence of any driving node.
CIM/CIU 300 has no bias resistors.

Plus Red Positive
Minus Green Negative
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.
2.4 Setting the BACnet transmission speed
Set the transmission speed correctly before CIM 300 is ready to
communicate on the BACnet MS/TP network. Use 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
2.4.1 DIP switch settings
Available transmission speeds in bit/s: 9600, 19200, 38400 and
76800.
Use 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 will be effective
immediately after setting the values of the DIP switch.
2.5 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, i.e. on all
interconnected networks.
CIM 300 offers two different approaches to setting the BACnet
Device Object Instance Number: default and custom, both
described in the following subsections.
2.5.1 Default Instance Number
By default, 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
2.7 Selecting the BACnet MAC address
2.5.2 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 will immediately set 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.
9
English (GB)

2.6 Selecting the Device Object Name
The property Device_Name is a character string that must be
unique inter-network-wide. By default, the name will be constructed
as "Grundfos - XXXXXX" where XXXXXX is the current Device
Object Instance Number as described in 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 will be stored in the device and replace
the default naming scheme.
Related information
2.5 Selecting the Device Object Instance Number
2.7 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 will
result 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.

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

2.9 Cable length
The maximum recommended 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
use of a screened, twisted-pair cable with a characteristic
impedance between 100 and 130 Ω.
2.10 LEDs
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 CIM 300 and the Grundfos pump.
2.10.1 LED1, BACnet MS/TP communication

6. Detailed description
6.1 Fault monitoring and resetting
This example shows how to monitor faults or warnings in the Grundfos pump and how to manually reset a fault.
The Fault code object (AI, 0) and the Warning code object (AI, 1) can both hold a Grundfos-specific fault code.
Warnings are notifications only and will not stop the pump, whereas faults will stop the pump. Most pumps can be configured to either
automatically reset the fault when the fault condition disappears, or to require manual resetting.
If a fault is to be manually reset, use the Reset fault object (BO, 0). When the Present_Value of this object is set to 1, a Reset fault command is
sent to the device.

Step Action
1 Install CIM 500 in the Grundfos E-pump according to the pump documentation.
2 Select position 2 at the protocol rotary switch.
3 Power on the E-pump, and observe LED2 turn permanently green and LED1 remaining off.
4Complete the pump configuration, for example sensor configuration and selection of local Operating mode, local Control mode and local Setpoint,
for example with Grundfos GO Remote.
5 Connect one of the CIM 500 Ethernet ports (RJ45) to a PC using an Ethernet cable.
6 Configure the PC Ethernet port to the same subnetwork as CIM 500, for example 192.168.1.1, and the subnet mask to 255.255.255.0.
7Open your internet browser and make contact to the CIM 500 webserver.
Default: 192.168.1.100
8
Log in to the webserver. Default:
User: admin
Password: Grundfos.
9 In the menu column to the left select: Configuration > Real time Ethernet protocol
10 Type in the required settings for BACnet IP.
11 Click [Submit] to transfer the new settings, and close the web browser.
CIM 500 is now ready to be accessed from a BACnet IP master via one of its Ethernet ports. Use the IP address selected under step 9.
• The CIM 500 LED1 will be flashing green when BACnet IP communication takes place.
• You can use the two Ethernet ports for daisy chaining of CIM 500 modules.
• It is possible to have connection to the webserver simultaneously with a connection to a BACnet IP master.
• It is possible to have connection to more BACnet IP masters simultaneously, for example to have connection to PC Tool CIM/CIU while connected to another
BACnet IP master.
