, based on the network hardware, CPU cycle time,
and Peer-to-Peer profile. This parameter will be optimized later.
MsgNr Counter (32-bit resolution) for all messages sent to a controller. In the illustration above, Robot A has sent message no.
54980 to Robot B.
AckMsgNr The number of the received message that the controller has to acknowledge. In the illustration above, Robot A has
acknowledged message no. 54979 from Robot B.
DataSeq Counter (16-bit resolution) for sent messages, which contain process data. In the illustration above, Robot A has sent
data message no. 54980 to Robot B.
Opens Number of successful connects to a controller.
A figure higher than 1 indicates that a controller dropped out and has been reconnected.
Resends Counter (32-bit resolution) for messages that have been resent due to an elapsed ResendTMO.
BadMsgs 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 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 (see Define Peer-to-peer Parameters on page 186 ).
ResendTMO Resend Timeout as set by the profile.
AckTmo Acknowledge Timeout as set by the profile.
CurKeVer CRC for the peer-to-peer configuration. Identical to the Peer-to-Peer system signal version (see page 181 ).
NewKeVer Reserved for future use.
