Chapter 2 RFID PGL Commands
38
idir
Enter a plus sign (+) or leave the field blank to
increment (default). Enter a minus sign (–) to
decrement.
step
A decimal number specifies the amount to increment/
decrement each time the form is executed. The
increment is at bit level and will automatically wrap
based on the field size.
RPT
n
The optional incremental repeat count parameters to
specify the number of times a particular field value is
repeated before it is incremented. The default repeat
count parameter
n
is 1, which will increment the field
value each time it prints. The repeat count can range
from 1 to 65535.
RST
n
The optional incremental reset count parameter to
specify the number of times an incremented field is
printed before it is reset to the starting value. By
default, there is no reset count. The reset count
parameter
n
can range from 1 to 65535.
startdata
Defines the value of the field or the starting value of the
incremented field. If the field is dynamic, the value will
be specified later in the EXECUTE mode. The data
must be specified within a pair of delimiters (D). The
delimiter (D) cannot be a “/” or SFCC character since
the “/” will comment out the rest of the line and SFCC is
reserved for PGL commands. If “R” or “S” is used as
delimiters, the data pattern must not comprise of the
keywords in the incrementing options. Since the
delimiters could be different from one value to another,
proper care must be taken to avoid one of the letters
mentioned above.
NOTE: 1. The RFWTAG command cannot be mixed with
RFWRITE in the same form.
2. Each field structure must be specified in a single line and
in the order it appears in the RFID tag from MSB bits to
LSB bits (left to right). The sum of all the field lengths must
match the size of the tag.
3. The host data are read in as ASCII characters. They
would be converted to binary representation for the base
