SECTION VARIABLES (BY POSITION):
Selecting the desired node it is possible to add a variable. In order to
create a new variable it is necessary to fill these items:
To use the created variable the field “ Enable Variable ” must
be checked. If you have created a variable but for the moment
it is unused it is possible to uncheck the field “Enable Variable”
without delete it;
In the field “ Description ” it is possible to write a description of
the variable (it isn’t a necessary information, it helps the
readability of the tree of network);
The field “ Dimension ” is used to select the dimension of the
variable (8, 16, 24, 32, 32 real, 48, 64 bit, Variable Length);
In the field “ Length(Variable Len) ” insert the length of the
data in the case of the dimension is “Variable Length”;
If the field “ Scale ” is checked, the converter reserves a bytes
on EtherNet/IP array with Scale value (see page 26 for more
info);
If the field “ From BCD to Integer ” is checked the converter
converts the BCD value of variable in Integer format. This
happens only if the variable is in BCD format; if it isn’t nothing
changes.
If the field “ SWAP ” is checked, the bytes of data of that variable are swapped. Example: from 0x01020304 to 0x04030201;
If the field “ Use Six Bytes for the Time Point ” and the “Type of Data” is “Time Point”, it is possible to read the information of Year,
Month, Day, Hour, Minutes, Seconds on six consecutive positions of the array without decoding (if not selected, the values are the
same of the reply of the slave device, so coded with a determinate structure (page 27 for more information)).
If the field “ Force Integer 32 ” is checked the converter maps the variables with a dimension <32 bit in 4 bytes of the EtherNet/IP
array as Int32 value.
In the field “ Position ” the position of the variable inside the M-Bus frame sent by the M-Bus slave is defined.
Having completed this fields, to add the variable the button “
ADD VARIABLE ” must be pressed.
In order to modify a created variable it is necessary to select the desired variable, change the wrong items and then press the “
MODIFY
VARIABLE ” button.
