Safety notes



The device is not allowed to be used outside the specified field of application.



It may be installed only by suitably trained personnel.



The device does not contain any parts that can be replaced or repaired by the user

and may only be opened at the manufacturer's site.

Product features

Mode of operation

The UK24MOD allows the actuators to be controlled digitally via the MP-Bus and send back

their current operating status. The control system information and the response is administered

in registers in the UK24MOD and can be processed with Modbus commands. This permits the

actuator functions to be integrated directly into the Modbus.

Sensor linking

One sensor can be connected per MP/MFT(2) actuator. This can be a passive resistance

sensor (PT1000, NI1000 or NTC), an active sensor (output DC 0…10 V), or a switching contact.

This provides a straightforward way of digitising the analogue signal of the sensors with the

Belimo actuator and transferring it via UK24MOD to the Modbus.

MPL actuators don't provide a sensor input.

Installation and commissioning

Installation and wiring

The device is mounted on 35 mm top hat rails. The wiring is accomplished with plug-screw

terminals.

Commissioning and parameterisation

Commissioning requires no configuration tools.

The Modbus parameterisation of the device is accomplished with DIP switches (address, baud

rate, parity, bus terminator, polarisation). The option exists of setting the response delay via

The addressing of the MP actuators is accomplished either with the keys under the front cover

or with the Belimo PC-Tool MFT-P.

The MP-Bus assignment is determined automatically and continuously updated. No backup of

the network structure takes place.

Dimensioning of the supply

Also take into account the dimensioning

specifications of the connected

MP/MPL/MFT(2) actuators!

The wiring of Modbus RTU / RS485 is to be carried out in accordance with applicable directives

(www.modbus.org). The device possesses resistors which can be switched on for bus

connection and biasing.

Note: The GND of the RS485 line is galvanically isolated from the MP-Bus GND.

Connection of the MP-Bus



The network consists of a 3-pin connection

(MP communication and 24 V supply).



Possibility of connecting a maximum of 8 MP/MPL/MFT(2) actuators per network.



Neither a special cable nor terminating resistors are required.



The signal conductor lengths (for calculation, see below) are limited:

–by the sum of the signal conductor data of the connected MP/MPL/MFT(2) actuators,

–by the type of supply (AC 24 V via the bus or DC 24 V via the bus),

–by the signal conductor cross-section.

Operation elements

Legend

The illustration shows the operation elements of the device with the front cover open.

Operation, behaviour

Setting the Modbus address

The Modbus address is set in binary form with the 8 DIP switches under the front cover. The

valid address range is 1-247. Values outside of this range will be interpreted as either 1 or 247,

respectively.

Operation, behaviour

(continued)

Setting the Modbus baud rate

The Modbus baud rate is set using the DIP switches under the front cover to the values 9'600,

19'200, 38'400 and 76'800.

The response delay of the device is set to a fixed 4 ms with 9600 Bd. A delay of 2 ms is used as

a default with higher baud rates. A longer delay can be set if needed via register 163.

The RS485 line must be completed at both bus ends with one resistor each. A suitable 150



element is present in the Gateway which can be switched with DIP switch 1 on the base plate.

The RS485 line can be polarised with two resistors (DIP switches 2 and 3) in order to reduce

interference effects during communications pauses. The biasing is implemented as a rule at one

of the bus ends. Switches 2 and 3 must always be respectively activated or deactivated

together.

The character transmission uses either the settings NO parity (1 start bit, 8 data bits, no parity,

2 stop bits) or EVEN parity (1 start bit, 8 data bits, even parity, 1 stop bit), The setting is done

with DIP switch 4.

Important:

The generally valid guidelines for RS485 / Modbus RTU are to be observed!

Operation, behaviour

(continued)

Automatic scanning of the MP network

The MP-Bus assignment is determined automatically and continuously updated. No backup of

the network structure takes place. The actuator information (e.g. series number, actuator type)

is extracted as soon as one supported actuator is detected at the addresses MP1…MP8.

In the event of a communications interruption, the Gateway will discard the affected actuator

after 10 seconds and reset the actuator register. Monitoring of the actuator is accomplished

preferably with the Actuator type register (12).

Addressing MP actuators

The Gateway supports the assigning of addresses to the MP nodes by means of the keys UP,

OK and DOWN, located behind the front cover.

Procedure:

1. Press down the OK key and keep it down until LED1 and MODBUS are continuously

illuminated.

2. Select an address (LED1…LED8) with the keys UP and DOWN

3. Start addressing sequence with OK key

4. Acknowledge addressing of the respective actuator within 4 minutes;

(depending on the type, using the address key, direction of rotation switch, ...)

5. Successful acknowledgement is made visible by the rapid flashing of the corresponding

LEDx. Afterwards, the Gateway will switch to standard operation.

The addressing process can be interrupted at any time by pressing the OK key.

The de-addressing of a node is not supported.
