About this Manual This manual has been created to assist you in installing, configuring and using your Zlinx 485 Base module.

  • Page 5: About This Manual

    The Zlinx 485 family of products features a selection of operational modes, communications modes, Modbus and I/O combinations. The system is scalable making it easy to start with a few I/O points and build a system with the required I/O-Modbus mix.

  • Page 6: Chapter 2: Hardware

    The base module is connected to a PC that is running the Zlinx 485 Manager software. Zlinx 485 systems can operate in Modbus or Peer-to-Peer modes. In Modbus mode a Zlinx 485 system exchanges Modbus messages with a Modbus capable base module.

  • Page 7: Expansion Modules

    Base Modules Each Zlinx 485 system is built around a base module. Base modules provide Modbus, digital and/or analog I/O and communicate with other Zlinx nodes. Several different combinations of digital inputs (DI), digital outputs (DO), analog inputs (AI) and analog outputs (AO) are available. For example, the ZZ-NA-485 Base module features a combination of two AI’s, two AO’s, two DI’s and two DO’s in a package.

    Modbus ASCII/RTU Basics The Modbus protocol emerged in the mid-1970s as an early protocol for linking terminals with Modicon PLCs using a master/slave (sometimes called a master/client) relationship. A simple, open, message-based protocol, it caught on quickly and became a defacto standard in the industry.
