Determine tolerance of pallet side transport
Figure 4-7
Minimum distance from reader to reader
Refer to the field data of the reader for this value.
Minimum distance from transponder to transponder
Refer to the field data of the transponder for this value.
Calculation of the maximum amount of user data in dynamic mode
Step
1. Calculate dwell time of the
transponder
2. Calculate maximum user data
(n for reading or writing
max)
(FRAM area)
Result
A maximum of 172 bytes can be read or written when the transponder passes by.
