MsgNr The Counter (32-bit resolution) for all messages sent to a controller.
AckMsgNr The number of the received message that the controller has to acknowledge.
DataSeq The Counter (16-bit resolution) for sent messages, which contain process data.
Opens The number of successful connects to a controller.
A figure higher than 1 indicates that a controller dropped out and has been reconnected.
Resends The Counter (32-bit resolution) for messages that have been resent due to an elapsed ResendTMO.
BadMsgs The Counter (32-bit resolution) for received messages that are corrupted, or are not expected at that instant.
A corrupt message, for example, is a message with a wrong sender or with a faulty CRC.
An unexpected message, for example, is an ‘Open’ command, when the controllers are already connected.
EarlyMsgs The Counter (32-bit resolution) for received messages that are not in the correct sequence. If a message drops out and is
lost at the addressee, there is a gap in the received messages, and the next message comes early.
Receive Tmo Receive Timeout as entered by the user.
ResendTMO Resend Timeout as set by the profile.
AckTmo Acknowledge Timeout as set by the profile.

Identical to the Peer-to-Peer system signal.
