To read fields using UniArt
:
1.
Find the reading required in the MODBUS Registers Table.
2.
Note the Item Number from the Registers Table.
3.
Go to the correct File number.
Since File capacity in UniArt is limited to 128 parameters, the
information contained in the ElNet Pico fields is stored in several
files.
File number is determined by the Item number
File
#
0 contains Item number
1 - 128
File
#
1 contains Item number
129 – 256
File
#
2 contains Item number
257 – 384
File
#
3 contains Item number
385 – 512
4.
Go to the correct Point number within that file Point number is
determined by the formula:
Item number – [FILE X 128] = Point Number
E.G. 1 If the user the wishes to read Voltage Line 2 (Item No 2)
By applying the formula: 2 - [0 X 128] = 2
File = 0 and Point within that file = 2
E.G. 2 If the user the wishes to read 30
th
Harmonics for Volts Line1
(Item No 330)
By applying the formula: 330 - [2 X 128] = 74
File = 2 and Point within that file = 74
E.G. 3 If the user the wishes to read 7
th
Harmonic for Current Line 3
(Item No 467)
By applying the formula: 467 - [3 X 128] = 83
File = 3 and Point number within that file = 83
