Transmit confirm, Transmit NAK full, Full

Communicating with Devices on a DH+ Link	9-9

Status Field	Word(s)	Description
Transmit confirm	24	Number of SDA messages successfully sent to and acknowledged by the addressed station

Transmit NAK full	30	Number of times the station received a NAK to a message because the destination station was
		full
		This indicates that messages are being sent to the receiving station faster than the PLC-5
		controller can process them. Most likely, more than one station on the DH+ link is sending
		messages to the same station. Check to see that you are:
		not scheduling unnecessary traffic (e.g., your are sending continuous messages when you only
		need updates once per second)
		implementing report-by-exception so that data is sent only if it is new data

Transmit NAK misc.	25	Number of incoming SDA messages that were NAKed due to reasons other than the NAKed full
		and NAKed inactive counters (e.g., a NAK due to a bad CRC)

Transmit not ACKed	27	Number of SDA messages that were sent but were not ACKed by the receiving station
		The following could have occurred:
		message could have been NAKed
		an invalid ACK was returned
		nothing was returned
		This counter can indicate:
		a noise or a cabling problem
		the receiving station has been removed from the link
		the receiving station cannot communicate

Transmit NAKed SAP	31	Number of SDA messages that were successfully sent to but were NAKed by the addressed
		station because the SAP specified in the message was illegal

This counter should always be 0.
