Chapter 4: Configuration & Operation

Zlinx 485 Manager software is used to configure Zlinx 485 hardware. Using Zlinx 485 Manager, the system can be configured to operate in Peer-to-Peer or Modbus modes (receiving Modbus commands and data from a Modbus base module). Digital inputs can be configured to operate in Discrete (on/off) or Frequency Counter modes and analog inputs and outputs are configurable for voltage or current loop operation.

Configuring Zlinx 485

Zlinx 485 modules can be configured to operate as Modbus nodes or as serial links in Peer-to-Peer mode.

Configuring Modbus Mode

When the Zlinx 485 receives a Modbus message to write to a discrete output (0xxxx addresses in its memory map), the Zlinx 485 module turns on its corresponding digital output. If a message containing holding register data is received (4xxxx addresses in its memory map), the Zlinx 485 module converts the value to a voltage or current signal on the corresponding analog output.
