2.10 Remote display connection
To connect the remote display, use the dedicated cable (P/N PSTCON0*B0)
and the tLAN interface card (P/N IROPZDSP00). See the following diagram.
Also set a value >0 for parameter /tE, to display the reading on the remote
display.

2.11 Network connection
Warnings:
•
the RS485 converter (IROPZ485x0) is sensitive to electrostatic
discharges and therefore must be handled with extreme care;
•
check the documents on the IROPZ485x0 interface for connection
instructions, so as to avoid damaging the controller;
•
fasten the converter properly so as to prevent disconnection;
•
complete the wiring without power connected;
•
keep the IROPZ485x0 interface cables separate from the power cables
(relay outputs and power supply).
The RS485 converter is used to connect the ir33+, ir33+ wide and easy wide
controllers to the supervisor network for the complete management and
monitoring of the connected controllers. The system allows a maximum
of 207 units, with a maximum length of 1000 m. Connection requires the
standard accessories (RS485-USB converter, CAREL P/N CVSTDUMOR0)
and a 120 Ω terminating resistor to be installed on the terminals of the
last connected controller. Connect the RS485 converter to the controllers
and make the connections as shown in the fi gure. To assign the serial
address, see parameter H0. See the instruction sheets on the converters
for further information.

UPLOAD DOWNLOAD EXTENDED DOWNLOAD
•
load the parameters from a controller onto the key (UPLOAD);
•
copy from the key to a controller (DOWNLOAD);
•
extended copy from the key to a controller (EXTENDED DOWNLOAD).
Important: The parameters can only be copied between
controllers with the same part number. The UPLOAD operation can,
however, always be performed.
Copying and downloading the parameters
The following operations are used for the UPLOAD and/or DOWNLOAD
functions, simply by changing the settings of the dipswitches on the key:
1.
open the rear cover on the key and position the 2 dipswitches
according to the desired operation;
2.
close the rear cover on the key and plug the key into the connector
on the controller;
3. press the button and check the LED: red for a few seconds, then
green, indicates that the operation was completed correctly. Other
signals or the fl ashing of the LED indicates that problems have
occurred: see the table below;
4. at the end of the operation, release the button, after a few seconds
the LED goes off ;
5.
remove the key from the controller.
LED signal Error Meaning and solution
Red LED
fl ashing Batteries discharged at
start copy The batteries are discharged, the
copy operation cannot be perfor-
med. Replace the batteries.
Green LED
fl ashing Batteries discharged
during copy or at end
of copy During the copy operation or at the
end of the operation the battery le-
vel is low. Replace the batteries and
repeat the operation.
Red/green
LEDs fl ashing
(orange signal) Controller not compa-
tible The parameter set-up cannot be
copied as the connected controller
model is not compatible. This error
only occurs for the DOWNLOAD
function; check the controller P/N
and run the copy only for compa-
tible models.
Red and green
LEDs on Error in data being
copied Error in the data being copied. The
EEPROM on the controller is cor-
rupted, therefore the data cannot
be copied to/from the key.
Red LED on
steady Data transfer error The copy operation was not com-
pleted due to a serious error when
transferring or copying the data.
Repeat the operation, if the pro-
blem persists check the key con-
nections.
LEDs off Batteries disconnected Check the batteries.

Note: the DOWNLOAD operation (normal or extended) is possible
even if the operating and control parameters are incorrect; in this case,
they will be recovered from the key. Be careful when recovering the unit
parameters from a key, as these determine the low-level operation of the
controller (unit model, type of interface, assignment of logical relay to
physical relay, brightness of the display, level of modulation of the relay
control signal …). The unit parameters from the original model must
therefore be restored to ensure correct operation of the controller.
