First in the list there are sensors connected to the first port from 1 to 8, then to the second port
from 1 to 8, and the second port will be indicated as be (P2) at the upper right part of the UPES
screen. In the lower line the type «None» will be indicated. It means that the type will be
determined automatically during the search for the sensor and the sensor MODBUS address that
will be identified with the channel board. The sensors with a null address will not participate in
the search. It is required to fill in the MODBUS addresses of the sensors, starting from the first
sensor. To set the MODBUS address of the sensor press the "+" and "−" buttons.
When setting the MODBUS addresses in this menu, the addresses that have been already input
are taken into account, therefore, when selecting the MODBUS addresses with the "+" and
"−"buttons, the addresses already input will be ignored. It protects against the input of the
repeated addresses to search for the sensors.
When you have entered the desired address, press the (Test/Enter) button to record the address
in memory, this address will be in the square brackets. To edit the MODBUS address of the
next sensor it is required to press the (“Prog”) button. Having entered the required number of
addresses, do not change the MODBUS addresses of the remaining sensors, i.e. leave them
equal to zero, press the ("Prog") button until you get to the (“Address Search”) menu. In this
menu to launch the search program press the "+" and "−" buttons to select ("Yes") to launch
the search program or ("No") to refuse from searching the sensor and press the ("Prog")
button, in this case the channel board will operate with previously detected sensors.
After you select the search program, press the ("Prog") button to start the search program. The
channel board will attempt to establish communication with the sensors by the set MODBUS
addresses and to determine their type. When the search is complete, the UPES display will
display the number of the sensors found. As soon as the channel board finds at least one
sensor, the channel board controller goes to the sensors control and parameters measurement
state.
