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 8 shows 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.

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.

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.

With this setting, the other control bits in the

ControlModule will have no influence.

The DDD system will be set to remote mode and operate

according to the operating mode and setpoint set in the

ControlModule. The other control bits in the

ControlModule will also be active.

0: For stopping the DDD system remotely.

1: For starting the DDD system remotely.

0: Copy to local settings inactive

Copy to local settings active. Switching the DDD system

from remote to local will not influence the behaviour of the

DDD system.

English (GB)

7.2.3 Explanation to control mode

Control enumeration for selection of the remote control mode.

H: Pressure (head)

Q: Flow

Important:

When using the CIM 150/500 with the DDD system, the following

limitations in the setup of the primary sensor (feedback sensor)

apply:

• Only sensor 1 (AI1) can be used as primary sensor.

• The primary sensor must have a minimum value of 0 for the

Setpoint and FeedBack scaling to be correct.

Control modes Description Illustration

> ConstHead (3)

> ConstPressure (4)

The setpoint of the DDD system will be interpreted as

setpoint for the pressure.

In these modes, the DDD system operates in closed-loop

control mode and will adapt its speed so that the pressure is

constant, regardless of the flow.

A pressure sensor is required.

TM04 2290 2208

> VarDiffPress (6)

The setpoint of the DDD system will be interpreted as a

proportional-pressure setpoint as shown in the figure.

This is a closed-loop control mode, and a pressure sensor is

required.

TM04 2291 2208

> DDD AUTO

ADAPT

(128)

The setpoint of the DDD system will be interpreted as a

proportional-pressure setpoint as shown in the figure.

The proportional curve will be adjusted automatically once a

day according to remote DDD sensor data.

English (GB)

7.2.4 Explanation to operating mode

Control enumeration for selection of the remote operating mode.

7.2.5 Explanation to Setpoint

The 16-bit data item setpoint accepts values ranging from

0-10000 corresponding to 0-100 % of feedback sensor range.

This is illustrated in fig. 13.

The setpoint is always a pressure setpoint. In DDD AUTO

ADAPT

it is the maximum permissible setpoint of the system. A setpoint

of 0 does not imply a stop.

Fig. 13 Closed-loop setpoint

Example

If the control mode is set to constant pressure, and the pressure

sensor range is 0-10 bar, a setpoint of 80 % will result in an

effective setpoint of 8 bar.

If the sensor range was 0-16 bar, a 50 % setpoint would be 8 bar,

a 25 % setpoint would be 4 bar, and so on.

Fig. 14 Example of setpoint for constant pressure, with a

pressure sensor range of 0-10 bar

AutoControl

This is the normal mode and cannot be changed.

The DDD system is controlled according to the selected

control mode and setpoint.

7.2.6 Explanation to status module

AccessMode

Status bit indicating whether the DDD system is controlled from

the bus or from some other control source.

To allow the DDD system to be controlled from PROFIBUS/

PROFINET, the RemoteAccessReq control bit in the

ControlModule must be set to "1". 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

set the AccessMode to "0", indicating that the actual control

source is not PROFIBUS/PROFINET.

OnOff

Status bit indicating whether the DDD system is started or

stopped.

The DDD system can be started/stopped from the bus by using

the OnOff control bit in the ControlModule.

"Started" does not necessarily indicate that the DDD system is

pumping as it might be in a "low-flow stop" condition.

Fault

Status bit indicating that the DDD system has been stopped due

to an alarm.

Warning

Status bit indicating that the DDD system has a warning.

CopyToLocal

Status bit indicating that the DDD will copy remote settings to

local settings when it is switched from remote access mode to

local access mode. The involved settings are control mode,

operating mode and setpoint.

ResetFaultAck

Acknowledge bit belonging to the ResetFault control bit. It will be

set when the control bit is set and the command has been

executed. It will be cleared when the control bit is cleared.

SetPointInfluence

Status bit indicating if the setpoint is influenced (e.g. by analog

input). If influenced, the ActualSetpoint (module 29) will differ

from the UserSetpoint (module 37).

Rotation

Status bit indicating that the DDD system is pumping.

ProcessFeedback

This is the value of the controlled process variable (feedback/

primary sensor). The process variable can always be compared

directly with the ActualSetpoint variable. If no setpoint influence is

active, it can also be compared with the setpoint variable in the

ControlModule.

See section 7.10 System measurement modules.

ControlMode

Status enumeration showing the actual DDD system control

mode.

See section 7.2.3 Explanation to control mode for detailed

explanation to the various control modes.

OperatingMode

Status enumeration showing the actual DDD system operating

mode. For a DDD system it is always 0=AutoControl.

The DDD system is controlled from a local source

(CU 354) or from an external digital input.

1: The DDD system is controlled from the bus (remotely).

0: The DDD system is stopped (off).

1: The DDD system is started (on).

0: No alarm.

7.9 Alarms and warnings

In the WarningCode module, the cause of a DDD system warning

can be read. A warning has no influence on the DDD system

operation.

In the FaultCode module, the cause of a DDD system alarm can

be read. A DDD system alarm will always lead to a reaction in the

DDD system operation, usually all pumps will be stopped, but

some DDD alarms have programmable alarm action types.

The complete list of possible alarm/warning codes is shown

below.

This can be automatic (A) or selectable Automatic/Manual

(A/M).

This can be None or programmable (Prog.).

All the data items ControlModule. setpoint, StatusModule.

ProcessFeedback, ActualSetpoint and UserSetpoint have a

scaling relative to the feedback sensor. By using the scaling

information of the feedback sensor (FeedbackSensorUnit,

FeedbackSensorMin, FeedbackSensorMax), these data items

can be expressed in absolute units.

Many of the DDD system measurement modules require a

particular sensor to be present. As a limited number of sensors

are available, only a few of the measurement modules can be

available simultaneously.

The table below shows the relation between the PROFIBUS/

PROFINET measurement modules and the sensor value selected

on the CU 354.
