Modbus/TCP 7-5

I/O Data Format

The BridgeWay transfers I/O data between Modbus/TCP and DeviceNet without

regard to data content or format. Due to this, the user is responsible for making

sure that the devices on either network understand the format of the data.

DeviceNet is a little endian protocol; values are transmitted least significant byte

first. Hence, all data in the I/O tables is assumed, by the DeviceNet nodes, to be

stored as little endian.

Care should be taken to make sure that the Modbus/TCP master handles input data

and transmits output data in a format acceptable to the target DeviceNet devices

(least significant byte first).
