^RT – Read Tag
The format for the ^RT instruction is: ^RT#,b,n,f,r,m,s
where
^RT = Read Tag command
# = Number to be assigned to the Field
Default value: 0
Other Values: 1 to 9999
b = Starting Block Number
Default value: 0
Other values: 1 to n, where n is the maximum number of
blocks for the tag
n = Number of blocks to read
Default value: 1
Other values: 2 to n, where n is maximum number of blocks
minus starting block number. In other words, if the tag has 8
blocks (starting with block 0) and you’re starting with block 6,
n can be 2. This would give you block 6 and block 7
information.

r = Retries
Default value: 0
Other values: 1 to 10, number of retries
m = motion
