PLR6400 System

PLR6435 Protocol Master

PlantLinc family of modems was developed for short to medium-range in-plant wireless installations. PLR6435 primarily functions as a Master modem as part of the PLR6400 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 PLR6430 Remotes (384 I/O points)
  • Throughput 1200 Baud – 115.2Kbaud

Product Description

Unlock Seamless Wireless Protocol to  I/O Communication with PLR6435

Data-Linc developed the serial and I/O Plantlinc Family for short-range in-plant to medium-range installations to meet customer requests for a modem that replaces less reliable technologies with the same robust FHSS data transfer method as our premium SRM family but at a lower competitive price. Our PLR System offers the same key CIX features:

Experience the Power of Simplified Integration

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

Reliable Connectivity, Unmatched Performance

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

Elevate your connectivity with PLR6435 – a part of the PLR6400 System, your gateway to the seamless protocol to I/O interaction. Simplify, integrate, and thrive.
