RFID Protocols Data Parser (LLRP, ISO 18000-6B, ISO 18000-6C)

RFID READERS CONNECTOR

Latest version:5.0.1 build 1126.November 28, 2025.

This module integrates RFID readerswith Advanced Serial Data Logger, Advanced TCP/IP Data Logger, or Data Logger Suite. It acts as RFID middleware: it configures readers, receives and parses tag reports, applies pre-filters, and forwards structured variables to export modules or writes them to log files and databases. The module supports both client and server TCP/IP modes and EPC data logging for Class-1 Gen-2 tags.

Typical deployment places the Data Logger software on a central collection server. Readers interact with tags and send data to the logger over TCP or COM port. Depending on your network design and a RFID reader operation mode, configure either the logger as a TCP client or TCP server.

The module configures reader behavior automatically after a connection is established. You can set reader operation parameters such as converting UTC timestamps to local time, start interval for tag detection, detection duration, and antenna power behavior. These parameters trade off data granularity and traffic.

Data flow is deterministic:

1. The logger receives data packets from an RFID reader.
2. Parses tag reports and events.
3. Applies the configured logging filters (tag appears, disappears, changed fields, every reading, reader events).
4. Maps values into named variables and forwards them to export modules.
5. Saves transient variables for further processing.

PRACTICAL EXAMPLES

Example 1: Low traffic monitoring: configure the reader to start detection every 30 seconds and detect for 2 seconds. Set the logger to log only “When tag appears in field of view” and “When tag disappears from FOV”. The system will generate events only on transitions, reducing stored records while capturing presence changes for inventory gates.

Example 2: High-resolution analytics: set continuous detection (interval 0) and the “Every reading” logging option. This generates a stream of reads that includes RSSI and count per read. Use this mode for detailed tag movement analysis between antennas.

INTEGRATION WITH ADVANCED TCP/IP DATA LOGGER (SAMPLE)

Configuration steps for an LLRP-compatible reader:

1. Add a TCP/IP client connection to the reader IP and port 5084.
2. Select the LLRP Reader Protocol parser from the module lists and click Configure.
3. Set reader operation mode and data logging filters.
4. Map parser variables in a selected data export module (database, CSV,
   HTTP POST, etc.).

Sample incoming LLRP-derived data (raw conceptual view):

LLRP TagReport: EPC: 300833B2DDD9014000000000 AntennaID: 2 PeakRSSI: -62 FirstSeenUTC: 2026-01-02 08:00:00 LastSeenUTC: 2026-01-02 08:00:02 TagSeenCount: 3 

After parsing and applying the “When tag appears” filter, an export module receives variables:

DATE_TIME_STAMP = 2026-01-02 08:00:00 TAGREPORTDATA_EPCDATA = "300833B2DDD9014000000000" TAGREPORTDATA_ANTENNAID = 2 TAGREPORTDATA_PEAKRSSI = -62 TAGREPORTDATA_FIRSTSEENTIMESTAMPUTC = 2026-01-02 08:00:00 TAGREPORTDATA_LASTSEENTIMESTAMPUTC = 2026-01-02 08:00:02 TAGREPORTDATA_TAGSEENCOUNT = 3 

Exported CSV row example (file exporter):

2026-01-02 08:00:00,300833B2DDD9014000000000,2,-62,2026-01-02 08:00:00,2026-01-02 08:00:02,3

KEY FEATURES

• Supports LLRP reader integration in TCP client and TCP server modes.
• Supports ISO 18000-6B and ISO 18000-6C readers.
• Configurable reader operation: polling interval, detect duration, antenna control.
• Flexible data logging filters: on-appear, on-disappear, changed fields, every reading, reader events.
• Additional EPC tag capabilities (extended memory blocks).
• Handles multiple simultaneous reader connections.

SUMMARY

The LLRP Reader Protocol module for our data loggers enables enterprise grade RFID middleware functionality, including reader control, event filtering, and structured exports to fit inventory, access control, or tracking workflows.
