V750-series UHF RFID System User's Manual - PLCeasy

Command / Response format
(1) Read ID (RDID)
Command
RDID(S)[options...]
Response RDID[RC](S)[CNT](S)[ID1 with ITM1](S)...[IDn with ITMn]
[RC]: Response Code
[CNT]: Tag Count
[IDn with ITMn]: tagID with Items indicated by TIF option. Items are delimited by a
comma.
Note:
・ If EPC data length is “0” (zero), the ID shall be “*”.
*(S) Space character
Example 1) When command is processed with all options omitted and the R/W reads a single tag (Each
option item is specified with default values):
[Tx] RDID
[Rx] RDID0000 001 1234567890ABCDEF12345678
* Without any options, the command is executed with [–seq SOC –ant 1 -tmo 250] and EPC data
[1234567890ABCDEF12345678] is returned.
Example 2) When [SingleOnce, Antenna 1 and 2] is specified, the command is executed, and when the R/W
reads two tags:
[Tx] RDID -seq MOC -ant 12
[Rx] RDID0000 002 111111111111111111111111 222222222222222222222222
Example 3) When [MultiRepeat, Antenna 1-4, read items; PC+EPC+CRC, Antenna, Read count] is specified,
the command is executed, and when the reader reads a single tag:
[Tx] RDID -seq MRP -ant 1234 -tif PER,ANT,CNT
[Rx] RDID0000 001 3000111111111111111111111111ABCD,2,3
* The code is returned with comma-separation. EPC code including PC code; 3000 and CRC; ABCD,
antenna ID; 2, and read count; 3 are returned.
Example 4) When [MultiRepeat, Antenna; 1-4 (Antenna 1 is used as main antenna), Timeout; 1000ms] is
specified, the command is executed and then the reader read 10 tags:
[Tx] RDID -seq MRP -ant12131411 -tmo 1000
[Rx] RDID0000 010 111111111111111111111111 222222222222222222222222 ...(7
Tag IDs)... AAAAAAAAAAAAAAAAAAAAAAAA
Example 5) When an error occurred during communication process:
[Tx] RDID -seq SOC -ant 4
[Rx] RDID7011
* The error code [Code:7011] is returned.
