Operational Modes
3-7
3
•
Comparison operators
—
= equal; < > not equal; > greater than; < less than
(default is = for all masks)
•
Filter string
—
from 1 to 8 characters that you want to match in the tag
(maximum is 8 characters depending on the start address, default is ???????? for
all masks)
The ? character is an any character wildcard in the mask string (one undefined ASCII
character is represented by ?, one undefined hex character is represented by ??).
Note: “Int?rm?c” will match tags with “Int [any_character] rm [any_character] c”
The filter string can be defined in EasySet as an ASCII string or a hex string. This
choice affects how the filter string is displayed in the LCD (single ASCII characters or
dual hex values for each character). This filter string display format is independent of
the
Data format selection (ASCII/hex) in the LCD settings Setup menu.
Tag Read Settings
This feature activates/deactivates from 1 to 4 read fields (you can combine fields to
read from more than one field in the same tag). Field 1 is active by default.
Note: You can only read from the activated fields if the Tag Read function is activated.
Use the Tag Filter/Read function if you only want to read from tags that match certain
criteria. Use EasySet to define the read parameters for each field:
•
Start address
—
position of the first character you want to read (any position in
the tag between 0 and 127, default is 24 for field 1 and 0 for the other fields)
•
Field length
—
number of characters you want to read (maximum is 32
characters depending on the start address, default is 8 for field 1 and 0 for the
other fields)
Tag Write Settings
This feature activates/deactivates from 1 to 4 write fields (you can combine fields to
write to more than one field in the same tag). No fields are active by default.
Note: You can only write to the activated fields if the Tag Write function is activated
(see “Autonomous Mode” on page 3-3).
Use the Tag Filter/Write function if you only want to write to tags that match certain
criteria.
Use EasySet to define the write parameters for each field:
•
Start address
—
Position of the first character you want to write to (any position
in the tag between 24 and 127, default is 24 for all fields)
•
Field length — Number of characters you want to write (maximum is 32
characters depending on the start address; default is 0 for all fields)
