2.1 Wireless devices network
The electronic position indicators DD52R-E-RF is compatible with Elesa wireless
network which allows electronic position indicators to communicate with a PLC
via radio.
Elesa wireless network is made by the following components:
- One control unit UC-RF
- Max 36 device as DD51-E-RF, DD52R-E-RF or MPI-R10-RF
The control unit UC-RF is provided with a standard interface for the most
common industrial busses to be connected to the PLC and allows the information
transmission between the PLC and the electronic position indicators DD52R-E-RF.
The control unit UC-RF exchanges information with the electronic position indicators
DD52R-E-RF via radio frequency and allows the setting of the target position and the
control of the current position of each indicator, directly from the PLC.
WARNINGS!
Read the control unit UC-RF instructions for more details regarding its configuration.
3 Assembly
1. Drill a Ø 6x10 mm hole in the body of the machine with a 30 mm centre
distance from the shaft to fit the rear referring pin.
2. Fit the indicator onto the spindle and make sure that the referring pin fit the hole.
3. Clamp the boss to the spindle by tightening the grub screw with hexagon
socket and cup end, according to UNI 5929-85.

(see cap. 8 for details).
7.6 RF version (DD52R-E-RF)
7.6.1 Programming the network parameter (nEt id) and the channel parameter
(nEt ch)
The radio network of the system is defined by the following two parameters:
nEt id : id 00/99 (NetID = 03 is reserved and is not possible to be used)
nEt ch : ch 01/36
These parameters can be configured in the radio menu of the indicator (see
cap. 8) and they must be set according to the PLC recipe in order to guarantee a
perfect communication between the control unit UC-RF and the electronic position
indicator DD52R-E-RF.
Warning
For the DD52R-E-RF with firmware release equal to 5.1 or higher, channel 1 is
equivalent to channel 4 of the previous version. Consider it in case of use of the
old system with UC-RF with fw release lower than 5.1.

Press the key to select the next digit.
Press the key to confirm the value and go back to the list of parameters.
The numeric values of the parameters must be inserted
taking into account the selected unit of measure.

8.5 Parameter value
The parameter value depends on the unit of measure and resolution set.
The value may change according to the resolutions of mm and inch.
Es.
If rES mm = 1 and rES inch = 0.01
The max parameter in mm is -25399 ÷ 25399 because if we convert the
value in inch 25399 / 25.4 = 999.96 which is the max value visible on the display
with the res inch = 0.01
In case the parameter is 25400 it is not possible to show the converted value
