Use a screened, twisted-pair cable. Connect the cable screen to

protective earth at both ends.

Recommended connection

5.1 Setting the Modbus transmission speed

Set the transmission speed correctly before the CIM 200 Modbus

module is ready to communicate with the Modbus network. Use

DIP switches SW4 and SW5 to set the transmission speed. See

fig. 3.

Fig. 3 Modbus transmission speed

DIP switch settings

Available transmission speeds in bits/s: 1200, 2400, 4800, 9600,

19200 and 38400.

The first three transmission speeds are only available via

software settings, whereas the last three are available via DIP

switches.

Default transmission speed is 19200 bits per second, as per the

Modbus RTU standard.

Software-defined

When SW4 and SW5 are set to "software-defined", writing a

value to the holding register at address 00004 will set a new

transmission speed.

Use the following values for software-defined transmission

speeds:

This value is set to 1200 bits/s as default.

The communication interface does not support transmission

speeds above 38400 bits/s.

The software-defined transmission speed value is stored in the

communication interface and remains after a power-off.

5.2 Setting the parity

You can set the parity either manually by using SW3 or via

software-defined settings.

Manual setting of parity

Default byte format (11 bits):

• 1 start bit

• 8 data bits (least significant bit sent first)

• 1 parity bit (even parity)

• 1 stop bit.

The default setting of the CIM 200 Modbus module is even parity

(1 stop bit). It is possible to change the parity using DIP switch

SW3. You can change the parity no parity (2 stop bits). See fig. 4.

Software-defined parity and stop bits

When SW4 and SW5 are set to "software-defined", the value in

the holding registers at addresses 00009 and 00010 will override

the setting of SW3. See figs 3 and 4.

The software-defined parity and stop bit values is stored in the

communication interface and remains after a power-off.

5.3 Modbus address selection

A Modbus slave on a Modbus network must have a unique

address from 1-247. Address 0 is reserved for broadcasting and

is not a valid slave address.

The Modbus address is selected via the menu system in the

pump display.

5.4 Termination resistor

The termination resistor is fitted on the CIM 200 Modbus module

and has a value of 150 Ω.

The CIM 200 has a DIP switch with two switches, SW1 and SW2,

for cutting the termination resistor in and out. Figure 5 shows the

DIP switches in cut-out state.

Fig. 5 Cutting the termination resistor in and out

Control bits with a state event trigger behave like a ’state’ that is

forced upon the DDA pump. CIM 200/500 will attempt to make the

pump operate according to the ’requested’ state in the control

registers 00101-00103. Due to certain state/mode restrictions,

this might not always be possible (see explanation of the bit in

question). The ’actual state’ of the pump can be read from the

corresponding bit in the status registers 00201-00206.

Value change

Control bits/bytes with a value-change event trigger behave like a

command that is executed when the bit/byte changes its value.

CIM 200/500 will attempt to make the DDA pump operate

according to the ’requested’ value in the control registers 00101-

00103. The change will be reflected in the corresponding bit/byte

in the status registers 00201-00206. Bits/bytes that are controlled

by a ’value-change event trigger’ can be controlled from both

Modbus and the pump HMI. The last value change, no matter

from which source, will become active if not prevented by other

conditions (see explanation of the bit/byte in question).

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

status register 00203 which is set when the command is executed

and cleared when the control bit is written back to "0".

8.5 Control registers

Modbus registers used for the control of the DDA pump.

8.5.1 Explanation of control bits in control registers

RemoteAccessReq

Control bit used by the CIM module to activate control from

Modbus.

Deaerating

Control bit used to start and stop deaerating the pump.

If the pump has been stopped via the pump HMI (symbol ■ ), it is

still possible to start and stop deaerating the pump from Modbus.

If deaerating of the pump has been started from Modbus, it can

be stopped by pressing or on the pump.

AnalogMode

Control bit used to select type of analog input signal.

The toggling of this bit has no effect unless the pump is in

operating mode "Analog". The actual state (readable from

corresponding status bit) will be reset to 4-20 mA whenever

another operating mode is selected.

TimerMode

Control bit used to select timer mode.

SlowMode

Control bit used to slow down the suction stroke velocity.

Velocity

Control bit used to select SlowMode suction stroke velocity.

The toggling of this bit has no effect unless the pump operates in

SlowMode. The suction stroke will be reset to 50 % velocity

whenever SlowMode is disabled.

The pump can only be controlled via the pump HMI and

from its external signal inputs. With this setting, all control

bits in control registers and writing to any output module

will have no influence.

The CIM module can control the pump according to the

settings in the control registers and the writing to the other

writable registers. The pump can also be controlled via

the pump HMI and from its external signal inputs.

0: Stop deaerating the pump.

Start deaerating the pump.

Equivalent to pressing .

0: 0-20 mA.

1: 4-20 mA.

Cycle timer mode.

The pump repeats a cyclical dosing of the batch volume

which can be programmed from Modbus with data

registers SetBatchDosingVolume and

SetBatchDosingTime.

Week timer mode.

Up to 16 time-controlled dosing procedures are defined

for a week. These procedures have to be programmed via

the pump HMI.

SlowMode disabled.

No slow-down of suction stroke velocity.

SlowMode enabled.

Slows down the suction stroke velocity to the velocity

selected with control bit Velocity.

0: Select SlowMode velocity 50 %.

1: Select SlowMode velocity 25 %.

English (GB)

AutoDeaeratingEnable

Data register 00319 OutputRelays, bit 2, will signal whenever

automatic pump deaeration is active.

FlowControlEnable

When the FlowControl function is enabled, various faults and

deviations related to the dosing process will be detected and

indicated.

The enabling/disabling of FlowControl means the enabling/

disabling of all alarms/warnings that are associated with flow

measurement. See section 8.10 Measurement data modules.

If the FlowControl function is disabled, the AutoFlowAdapt

function (see control bits AutoFlowAdaptEnable) cannot be

enabled.

ModbusWatchdogEnable

The Modbus software watchdog is used to monitor the Modbus

connection. If the connection is broken, the DDA pump will stop

dosing and indicate a Modbus communication fault. See section

8.11 Alarms and warning.

When "Bus control" is selected via the pump HMI, the Modbus

watchdog is automatically enabled every time the pump is

powered on. If Modbus communication is somehow interrupted

(no communication with a Modbus master), this will be detected

and the DDA pump will stop with an alarm indicating "bus error"

(event code 15).

Enabling of Modbus will at the same time automatically enable

the monitoring of the cable connection from the E-box to the DDA

pump (event code 152).

After power-on, the Modbus master can at any time control the

enabling and disabling of the Modbus software watchdog. The

monitoring of the E-box cable connection will follow this choice.

When "Bus control" is disabled via the pump HMI, the Modbus

software watchdog is also automatically disabled and so is the

monitoring of the E-box connection.

AutoFlowAdaptEnable

The AutoFlowAdapt function detects changes in various

parameters and responds accordingly to keep the flow constant.

Dosing accuracy is increased when this function is enabled.

The AutoFlowAdapt function can only be enabled if the

FlowControl function is also enabled.

PulseMemoryEnable

The pulse memory function can be used in operating mode

"Pulse". When it is enabled, up to 65000 unprocessed pulses can

be saved for subsequent processing.

ResetFault

When this control bit is toggled 0 → 1, the pump will attempt to

reset pending alarms and warnings and to restart the pump if it

was stopped due to an alarm.

Pulse

When this control bit is toggled 0→ 1, a pulse signal is sent to the

pump. This can be used in operating modes "Pulse" and "Batch"

and is equivalent to a pulse signal from the signal inputs.

ResetVolumeCounter

When this control bit is toggled 0 → 1, VolumeTripCounter (module

30) is reset to "0".

SetRTC

When this control bit is toggled 0 → 1, the internal real-time clock

(RTC) in the DDA pump will be updated. The values must have

been previously written to the SetDataTime (registers 00116-

00122).

8.5.2 Explanation of control mode

Control enumeration for remote start/stop of the pump.

0: Automatic pump deaeration disabled.

Automatic pump deaeration enabled.

The pump is automatically deaerated (degassed) at

regular intervals.

0: FlowControl function disabled.

1: FlowControl function enabled.

0: Modbus software watchdog disabled.

1: Modbus software watchdog enabled.

0: AutoFlowAdapt function disabled.

1: AutoFlowAdapt function enabled.

0: Pulse memory function disabled.

1: Pulse memory function enabled.

Value Name

ReqStart

If the pump is ready to be controlled from Modbus

(status register 00201: bit 0: ActRemoteAccess = "1"),

this value will start the pump and it will start dosing

according to the selected operating mode. If the pump

is stopped via the pump HMI, it will restart when

is pressed.

ReqStop

If the pump is ready to be controlled from Modbus

(status register 00201: bit 0: ActRemoteAccess = "1"),

this value will stop the pump and the pump HMI will

show . If the pump is stopped from Modbus, it

cannot be started via the pump HMI (unless "Bus

control" is deselected).

ReqStop cannot stop the pump when it is deaerating.

English (GB)

8.5.3 Explanation of operating mode

Control enumeration for selection of operating mode.

Value Name

Manual

In this operating mode, the pump constantly doses the

dosing flow set via SetpointManual (register 00106-

00107) or the pump HMI.

Pulse

In this operating mode, the pump doses the volume

set via SetPulseVolume (register 00108-00109) or the

pump HMI for each incoming pulse. Reception of the

pulse command from Modbus has the same effect as

an incoming contact pulse signal.

If the pump receives more pulses than it can process

at the maximum dosing flow, excess pulses will be

ignored if the memory function (PulseMemoryEnable

bit) is not enabled.

Analog

In this operating mode, the pump doses according to

the external analog signal. It can operate according to

a 4-20 mA or 0-20 mA signal selected via the

AnalogMode bit or the pump HMI.

If the input value in analog mode 4-20 mA falls below 2

mA, an alarm will be displayed and the pump will stop.

The relation between analog signal and dosing value

is called analog scaling and must be set via the pump

HMI.

Timer

The time the dosing should take place is controlled by

a cyclic timer or by week timers. The selection is done

via the TimerMode bit or the pump HMI. Some other

parameters are related to timer dosing. They can only

be programmed via the pump HMI.

Batch

In this operating mode, the pump doses the volume

set via SetBatchDosingVolume (register 00110-00111)

over a time period of SetBatchDosingTime (register

00112-00113) for each incoming pulse (or Modbus

Pulse command).

The remaining batch volume during dosing can be

read from RemainingDosingVolume (register 00310-

00311).

English (GB)

8.6 Dosing settings

Unless otherwise stated, the data type used for counters and

scaled values is always an unsigned integer.

00115 SetOutputRelays Bits

Used to enable and disable the output relays 1 and 2.

A relay has to be set to "Bus control" via the pump HMI if it is to be controllable

from Modbus via the SetOutputRelays register. Via the pump HMI, the relays can

also be individually configured to be of type NO or NC.

Bit 0: Relay 1 control:

0: Not active

1: Active.

Bit 1: Relay 2 control:

0: Not active

1: Active.

The present status of the output relays can always be read from OutputRelays

The analog output has to be set to "Bus control" via the pump HMI if it is to be

controllable from Modbus.

The present value of the analog output signal can always be read from

AnalogOutput (register 00317).
