OMMUNICATIONS

4.1. Implementation

Basics

The Wi-MGR is capable of communicating via the half-duplex EIA-485 serial communication

standard. The Wi-MGR is configured to act as a slave device on a common network. The

EIA-485 medium allows for multiple devices on a multi-drop network. The Wi-MGR is a

slave only device and will never initiate a communications sequence.

4.1.1 Modes of Transmission

The Modbus protocol uses ASCII and RTU modes of transmission. The Wi-MGR supports

only the RTU mode of transmission, with 8 data bits, no parity and one stop bit. Every

Modbus packet consists of four fields:

♦

Slave Address Field

♦

Function Field

♦

Data Field

♦

Error Check Field (Checksum)

4.1.1.1 Slave Address Field

The slave address field is one byte in length and identifies the slave device involved in the

transaction. A valid address range is between 1 and 254. The slave address is set from the

Com Port1/Modbus/Bacnet Configuration

webpage.

4.1.1.2 Function Field

The function field is one byte in length and tells the Wi-MGR which function to perform. The

supported functions are 03 (Read 4xxxx output registers), 04 (Read 3xxxx input registers), 06

(Preset single register), 16 (Preset multiple registers).
