Chapter 9 Write Single Block RSLogix 5000 Code Examples The Write Single Block command writes one block of user data to an RFID tag. Set the following values in the output image table: a. xx:O.Channel[0].Command = 10 b. xx:O.Channel[0].Address = starting address to write c. xx:O.Channel[0].BlockSize = 0, 4, or 8 d. xx:O.Channel[0].Data[0…112] = data to write e. xx:O.Channel[0].Length = 0, 4, or 8 f. xx:O.Channel[0].BlockSize = 0, 4, or 8 g. xx:O.Channel[0].Reset = 0 h. xx:O.Channel[0].Timeout = 0 i.
Chapter 9 RSLogix 5000 Code Examples Example Results The output image table shows that the address is set to Block 3; the block size is 4 and the command is 10. The data to be written to block 3 is 41, 42, 43, and 44. Upon successful completion of the write block command, the Input Image table shows that Command = 10 and ChError = 0. The input channel data fields are all zero. Use the Read Single Block command (=1), with option flag set to zero, to read the contents of the tag in block 3.
Chapter 9 RSLogix 5000 Code Examples Continuous Read Mode The Continuous Read command is used for specialty applications that require high line speeds (up to 3 ms). See Continuous Read Mode on page 114 for details on this command. Stop Continuous Read The Stop Continuous Read command is used with the Continuous Read command for specialty applications that require high line speeds (up to 3 ms). See Continuous Read Mode on page 114 for details on this command.

Chapter 12 RFID Tag Speed Table 27…Table 30 on page 114 are guides to help determine the amount of information that can be written to/read from an RFID tag, which is based on the speed of your application. For example, to read 8 bytes consistently from a tag using the square transceiver, your line speed must be 0.827 ms or slower. If you have a high-speed application, it is best to choose the largest transceiver, larger tag, which provides the largest antenna range.

Chapter 12 RFID Tag Speed Modes of Operation Only one type of mode of operation can be used on each channel. To change modes you must issue a Stop Continuous Read, and then reissue a Start Continuous Read with the new mode. Both channels can be configured for the same mode or different modes simultaneously. Modes of operation are limited based on the model number of the interface.
Chapter 12 RFID Tag Speed Command Structure a. xx:O.Channel[0].Reset =0 b. xx:O.Channel[0].Command = 5 c. xx:O.Channel[0].BlockSize = Bytes per Block in the tag d. xx:O.Channel[0].Address = Starting Block e. xx:O.Channel[0].Length = Number of blocks to read f. xx:O.Channel[0].Timeout = Delay time between sending commands g. xx:O.Channel[0].UIDLow = 0 h. xx:O.Channel[0].UIDHi = 0 i. xx:O.Channel[0].Data[0] = Mode x j. xx:O.Channel[0].
Chapter 12 RFID Tag Speed If the interface is unable to obtain 10 good reads in a row, it decrements the delay time by 1 ms and starts again in phase 2. If the delay time has been decremented more than 30 ms from the average, the interface exits teach mode and reports back the recommended delay time of -1. A -1 value indicates that the interface cannot determine what the best delay time would be due to variations in tag speed.
