Section 5 EtherNet/IP Communications Protocol
System Errors
Device Information
The following table lists the device information that indicates the Reader/Writer in which the error
occurred.
These codes are set in the Response Information 1 field in the response area.
Communications Diagnostics Results
The following table lists the communications diagnostic results that are obtained when the Reader/
Writer communicates with an RF Tag.
If communications diagnostics are enabled, these codes are provided to indicate the cause when
diagnostics indicate that communications are unstable.
This information is set in the Response Information 2 field in the response area. When this information
is set, the RF_WAR (communications unstable) signal turns ON.
