Rockwell Automation 1769-SM2 Compact I/O DSI/Modbus Communication Module - Manual (Page 63)

Understanding the I/O Image 4-3
The Module Status Word (input word 0) is used for all channels, where:
The data valid bits (0…14) can be used in the ladder program to
determine if the received data is valid and can be used. Bit 15 provides
diagnostic feedback on the status of the 1769-SM2 module
configuration.
When the module is configured for RTU Master operation in
Multi-Drive mode, bits 0…14 are not used and will be “0.”
