Modbus Plus Addressing

Modbus Plus node addressing can be set using switches or via configuration software. To use

the switch address settings, the “Enable Switch Address” option in configuration software must

be selected, otherwise switch settings are ignored. NOTE – software address configuration is the

recommended option if use of the GDB Offset and Count parameters is required (see section

4.11.4).
Two sets of six switches are available: Node Address (S1, the left-most set of switches, closest to

the D-SUB connector), and Source Address (S2, the right-most set of switches). Address settings

for both switches use the same binary format illustrated in the table below.

Protocol & Supported Functions

Devices on a Modbus Plus network have two ways of exchanging data. One is through fast cyclic

I/O data called Global Data, and one through a somewhat slower Modbus protocol for point-to-

point parameter data transfer. The WI-GTWY-9-xxx supports both Global Data and point-to-

point data, however the module cannot initiate point-to-point commands but only respond to and

accept point-to-point commands initiated by other nodes on the network.
Modbus Plus is a token bus network. This means that each device on the network will receive the

token on a cyclic basis. When a device on the network receives the token it is able to broadcast

up to 32 words of Global Data. All other devices on the network will ‘see’ this data, and

depending on their configuration have the option to use some, or all, of the broadcast data.

Consequently, the WI-GTWY-9-xxx Modbus Plus module supports up to 32 words of Global

Outputs (i.e. Data To Network) and up to 32 words of Global Inputs (i.e. Data From Network).
The WI-GTWY-9-xxx also supports point-to-point data, however the module cannot initiate

point-to-point commands but only respond to and accept point-to-point commands. The WI-

GTWY-9-xxx Modbus Plus supports only the following point-to-point operations on Modbus

40000 (4X) registers:

-

(0x03) Read holding Registers

-

(0x06) Preset Single Register

-

(0x10) Preset multiple Registers
