6. Configuring the Gateway

-“Sub-Network Status…”: In “on-line” mode (see chapter 6.12.2 “ABC” Element, page 76), this command displays a window summarizing the values of the gateway’s error counters. These counters are also used by the gateway to update the value of its status word (see chapter 5.1.2 Gateway Status Word, page 35). The “Update” button allows you to refresh the values of these counters.

When you run this command in “off-line” mode, all of the values displayed are replaced by the word “Unknown” to show that they cannot be read on the gateway. The “Update” button then becomes inaccessible.

When the “Sub-Network” element is selected, you have access to all of the options allowing you to configure the gateway’s communication protocol format on the Modbus network. The various settings you can make are described below. All of the Modbus slaves present must support this configuration and be configured appropriately.

-Bitrate (bits/s): The gateway supports a limited number of communication speeds.

Choose the speed that suits your Modbus network.

-Data bits: 8 bits (required).

-Message delimiter (10ms): Period of silence added to the normal period of silence between the end of one

message and the start of the next message. The normal

period of silence corresponds to the time

taken to transmit

3.5 characters.

-Parity: Choose the parity according to the format chosen for communications on your Modbus network.

-Physical standard: RS485 (required).

-Start bits: 1 bit (required).

-Stop bits: 1 or 2 bits.
