PLR6535 - Part of the PLR6500 I/O System

PLR6535 Protocol Master

PlantLinc family of modems was developed for short to medium-range in-plant wireless installations. PLR6535 primarily functions as a Master modem as part of the PLR6500 system that offers an industrial-grade, cost-effective solution for protocol to I/O communication, setting a new standard in simplicity and efficiency.

  • Ultra reliable data transfer – hard-wired Ethernet connection avoids data loss
  • One Ethernet port- Ethernet/IP and Modbus TCP/IP compatible
  • One serial port – DF1 and Modbus RTU compatible
  • Supports up to 16 PLR6530 Remotes (384 I/O points)
  • Throughput 1200 Baud – 115.2Kbaud

Product Description

PLR6535: Seamless Wireless Protocol to I/O Communication Unlocked

Data-Linc’s introduced the serial and I/O Plantlinc Family to address short-range in-plant to medium-range installations. This solution responds to customer demands for a modem that replaces less reliable technologies with the robust FHSS data transfer method, akin to our premium SRM family, but at a more competitive price. Our PLR System encompasses the same key CIX features:

Experience Simplified Integration

  • The PLR Master utilizes Produce/Consume firmware, seamlessly integrating your PLR Wireless I/O network into a Logix PAC’s I/O tree.
  • No more message writing or I/O mapping – it’s that simple.
  • Our PLR Protocol Master’s EDS file streamlines integration with just a few clicks, providing all necessary tags for effortless installation.
  • Simply install the EDS file and, using RSLogix 5000 or Studio 5000, add the appropriate module with ease.

Reliable Connectivity, Unmatched Performance

  • Unlike other “Wireless I/O” devices struggling to maintain EtherNet/IP UDP connections, DATA-LINC’s proprietary “Wireless Protocol to I/O” technique ensures flawless operation.
  • Rest assured, common issues associated with “wireless Produce/Consume” are non-existent here.

Elevate your connectivity with PLR6535 – a part of the PLR6500 System, your gateway to the seamless protocol to I/O interaction. Simplify, integrate, and thrive.
