3 How to read the Address Data Table
All the information necessary to read/write data from/to a TPR is contained in the Address Data Table (see
Appendix A).
3.1 Address Data Table
Now a description of all the Address Data Table’s fields is given:
3.1.1 VAR
The VAR field contains the description of the variable.
An example of VAR fields could be: “Relay phase nominal current - In ”, “Relay reference name” or “I> Trip”.
3.1.2 REF
The REF field tells which data table the variable is stored in.
The REF field can assume one of the following values:
• 0x: data stored in the COIL table
• 1x: data stored in the DISCRETE INPUT table
• 3x: data stored in the INPUT REGISTER table
• 4x: data stored in the HOLDING REGISTER table
3.1.3 IDX
The IDX field represents the position of the table (specified by REF) in which the variable VAR is stored.
The IDX value is related to the Modbus address of the variable. The relationship between IDX and Modbus address
is the following:
MB address = IDX - 1
Example: let’s consider the following Address Data Table
VAR REF
IDX
DIM
Relay phase nominal current - In
3x 50 1
Relay reference name
3x 42 8
I> Trip
1x 7 1
Let’s see that the variable “Relay phase nominal current - In” is the 50th variable stored in the Input Registers
table (reference 3x) and its dimension is 1 Modbus register (DIM=1).
