DeviceNet™ Input Message Format
STS Status Byte
Bit 7 = Rx Buffer Empty
Bit 6 = Rx Buffer Overflow
Bit 5 = Rx Parity Error (automatically resets with new Rx message)
Bit 4 = Tx Buffer Empty
Bit 3 = Tx Buffer Overflow
RxC Receive Message Counter. Gateway increments RxC when new Rx Message is in Data field.
TxA Transmit Message Acknowledge. Gateway sets TxA equal to TxC after Tx Message is transmitted.
LENGTH Number of valid Rx Message bytes in the Data field.
DATA Fixed length field (0-64 bytes). Contains Rx Message bytes (left justified). Unused bytes are set to 0x00.
DeviceNet™ Output Message Format
CMD Command Byte
Bit 6 = Clear Rx Buffer (set bit to clear overflow error)
Bit 3 = Clear Tx Buffer (set bit to clear overflow error)
RxA Receive Message Acknowledge. Optional Rx handshake byte. Application sets RxA equal to RxC after processing last received message.
TxC Transmit Message Counter. Application increments TxC when new Tx Message is in Data field.
LENGTH Number of valid Tx Message bytes in Data field.
DATA Field length field (0-64 bytes). Contains Tx Message bytes (left justified).
