Monitoring DH+ Communication Channels

Use the DH+ status screen in your programming software to monitor channels that are configured to support a DH+ link. The data displayed is stored in the diagnostic file defined on the DH+ configuration screen in your programming software. Note that this screen does not display the active node table, which is also stored in the diagnostic file.

Monitoring messages

Status Field	Word(s)	Description
Sent	5	Total number of messages sent by the station
		This number is the sum of the send data acknowledge counters (SDA) and send data no
		acknowledge (SDN) transmit confirm counters.

Sent with error	7	Number of messages sent that were not acknowledged. This number is the sum of the following:
		SDA transmit NAK misc•SDA/SDN retrans
		transmit NAK full•dropped token
		SDA transmit NAKed SAP

Received	4	Number of error-free messages the station has received. This number is the sum of the SDA and
		SDN received counters.

Received with error	6	Number of invalid messages that the station has received. This number is the sum of the SDA
		received with error and the SDA received SAP off counters.

Unable to receive	8	Total number of times the station NAKed an incoming message due to the lack of an available
		buffer. This number should be the same as the SDA received but full counter.
