If you are using the EtherNet/IP or ControlNet adapter, it is suggested that
you use the COS/Cyclic connection status bits to determine the health of the
connection with a master.
The following are the status bits for the eight Peer connections:
•
Peer#X Data valid
•
Peer#X Exists
Use the Exists bits to determine if a connection is configured, and the Data
Valid bit to check if the data from the peer has been received in the expected
time (EPR) and with the expected data size.
Network
Network Input 0 through Network Input 7 are sent to the DeviceLogix
program through the Output Data assembly byte 1. In RSLogix 5000, the tag
name for these bits is UserDefinedBitData.
Reserved Bit 8 through Reserved Bit 31 are legacy bits and should not be used.
There are many Peer#X (Byte X Bit X) bits. This is a mapping of 24-byte bit
data for the eight peer connections. You need to know the Input Memory map
of each of the peers in order to use this data. See
Appendix A .
