Table 14 – EasyPlug commands / RFID operations matrix
--- : function / feature not supported
(*1) before the command for activation of write protection the access password must have been written to the tag
5.2 Legacy EasyPlug commands
In a RFID job you can write data to and read data from a tag. Use command RFW to write data to tags, und use
either command RT to read data from tag and print it on the label or the combination of command RFR and RFH to
get data via the defined communication interface.
These commands can be used all together mixed in one job. Data can be read in the same job when it is written to
the tag. Take care that the command that writes data must be placed before (lower line number) a read command
when this data should be read in the same job.
For the complete description of the RFID related EasyPlug commands #IM, #ER, #RT, #RFW, #RFR, #RFL, #RFH,
#RFC, #RM see “The EasyPlug manual” [A0164].
Note: Using the legacy commands is not the preferred way to read from and write data to a tag. The concept of
variable data handling gives much more flexibility for processing data before writing to the tag.
5.2.1 Read and Write operations
Operation Command(s) Notes
Read data from tag and print data
to label #RT
Write data to tag #RFW Auto increment of numeric values isn’t implemented => use
variable data handling approach instead
Special commands for proprietary
tag features #RFC allows control the EAS bit of HF tags
