UC-RF Control unit for DD51-E-RF DD52R-E-RF MPI-R10-RF

PLC connection, data transmission via radio frequency

2. Description

The control unit allows the communication between the RF electronic position indicators and measuring

system to a PLC.

Connected to an UC-RF, the PLC can read the current position of each indicator and transmit

a target position to all devices. This allows the PLC and consequently the operator to know the exact

situation and position of the command shaft and/or of the components of the machine.

The control unit (UC-RF) is a standard DIN rail module. This unit is provided with a socket for connection

to a power source, a standard industrial bus interface connector for the communication with the PLC

and an antenna output for the RF communication with the RF electronic position indicator and

measuring system (to be ordered separately).

2.1. Compatible devices

The UC-RF allows RF communication with the following Elesa products:

DD51-E-RF

DD52R-E-RF

MPI-R10-RF

2.2. Avaliable bus interfaces to the PLC

The standard interfaces available for the UC-RF are:

Ethernet/IP

Proﬁnet

Modbus/TCP

Other interfaces (Proﬁbus, Canbus, RS 232, RS 485 etc.) can be evaluated on request.

2.3. RF communication

The data exchange uses ISM SRD range of 2.400-2.480GHz.

The communication between the remote devices and the UC-RF follows a proprietary ELESA protocol.

2.3.1. Security

Since the communication between the indicators and the UC-RF follows a proprietary ELESA protocol

and the control unit cannot process anything different from the expected data, it is not possible to have

direct access to the PLC via the UC-RF. For this reason, the radiofrequency connection is protected

against system alteration or industrial espionage.

WARNING

The presence of interferences (various WI-FIs, BLUETOOTHs, etc.) will not affect the correct functioning

of the system but could increase the scan time due to discarded transmission packet.

Placing the UC-RF close to power elements (contactors, inverters, motors, etc.) should be avoided or,

if impossible, a minimum safety distance and/or shielding must be provided.

3. Connection and mounting

The UC-RF can be mounted on a DIN Rail thanks to a snap on connector on the rear of the device.

3.1. Power supply

The UC-RF control unit must be connected to a 24VDC +/-5% power supply with minimum current

capacity of 60mA. Even if the UC-RF power supply input is protected from the polarity inversion it’s

mandatory to pay attention to the polarities as printed near the power supply input on the plastic box

of the UC-RF; see the drawing below.

WARNING: The power supply line of the UC-RF has to be protected by a 100mA F type fuse.

The plug for the power supply connector is supplied with the UC-RF.

3.2. Connection to the PLC

The UC-RF must be connected to the PLC via an Ethernet RJ45 cable by using one of the two ports on the

front of it (see drawing below). Both ports are equivalent. In case two PLCs (or PLC+PC) are connected,

make sure that conﬂicts are avoided. For further speciﬁcations, refer to the speciﬁc communication bus

requirements.

3.3. Antenna

The antenna is supplied with the control unit. The antenna is suitable for mounting in applications

where the counterpoise will not be shielded from the antenna. The antenna must not be mounted inside

a metal cabinet; non-conductive or open metal enclosures or ﬁxings must be used.

If the counterpoise is within a shielded enclosure it will affect the antenna performance.

The antenna must be placed in the middle of the area where the remote devices are mounted. Ideally

where it is possible to avoid any metallic shielding in between. If necessary, extension cables can be

used. RG 174/U coaxial cable (ﬁtted with SMA male/female connectors) must be used, see on the Elesa

catalogue the available connection cables.

PLC connection, data transmission via radio frequency

However, the best solution is to keep the antenna directly connected to the UC-RF and install it where

it’s more convenient, following the hints above.

WARNING

The range of the radio link is up to 30m in line of sight. However, in industrial environments the real

range depends on many factors - presence of walls, machine parts, metal obstacles, etc.

An accurate choice of antenna position avoids communication issues.

4. System conﬁguration

The Elesa wireless network consists in up to 100 sub networks identiﬁed by a NetId number from 0 to 99.

Each subnet can address up to 36 remote devices, each transmitting on a different channel (Net CH).

The purpose of the subnets is to allow different machines to work near to each other with the same

device conﬁguration (as the communication channel) without interference.

Even though it is possible to switch a UC-RF to work on different subnets (different NetID), it is strongly

recommended to dedicate one UC-RF for each subnet.

Before starting the UC-RF, please ﬁx the parameter of the desired network by choosing NetId and Net_CH

for each remote device. Refer to the remote device user manual for their conﬁguration and setting.

WARNINGS

fNetID 3 must be avoided because it is reserved for special uses

4.1. IP address

MODBUS/TCP, Proﬁnet and Ethernet/IP protocol identify the interfaces with an IP address.

The UC-RF is factory set with the following parameters:

IP: 192-168.1.10 static

SN Mask: 255.255.255.0

A different IP/subnet can be assigned by the PLC, or using IPConﬁg utility downloadable from:

https://www.anybus.com/support/ﬁle-doc-downloads/compactcom-30-series-speciﬁc/?ordercode=AB6224

It is possible to enalble the DHCP function too.

5. UC-RF status LEDs

If the connection to a channel is successful, the GREEN LED ﬂashes.

If the connection is lost/transmission packet discarded, the RED LED ﬂashes.

During normal operation, occasional RED LED ﬂash can be observed. This is not an indication of failure.

If the control unit does not establish a connection to a channel after several consecutive connection

attempts, it will set the “off-air” ﬂag for that channel.

In power, on the RED and GREEN LEDs ﬂash for a few seconds. If the RED LED and the GREEN LED

keep ﬂashing alternatively, please check the connection to the PLC and/or the IP address conﬁguration.

If RED LED and GREEN LED stay ON, the UC-RF is waiting for the NEtId to be set. If RED LED stays

ON, please, contact Elesa customer service.
