ZPL II Commands for RFID^WT – Write Tag

The format for the ^WT instruction is:

^WTb,r,m,w,s

where

^WT = Write Tag command

b = Block Number

Default value: 0

Other values: 1 to n, where n is the maximum number of blocks for the tag

NOTE: This is the starting block number. If the user sends more than a block of data it will overflow into the next block. If the user overflows the block and subsequent blocks cause errors (write protects, beyond range, etc.), the write will be aborted, but blocks already written will not revert to original contents. It’s up to the caller to ensure blocks aren’t accidentally overwritten.

r = Retries

Default value: 0

Other values: 1 to 10, number of retries

m = motion

Default value: 0 (Feed label after writing)

Other value: 1 (No Feed after writing, other ZPL may cause a feed)
