VTAM® issues this message in response to a DISPLAY ID command requesting the status of a channel-attached node. For a DISPLAY ID command for a local NCP, this message is issued for every channel-attached link station defined from the host to the PU type 4.

sio is the number of start I/O operations counted for the channel. This number is cumulative (from the time that the node was last activated) and is expressed in decimal. The value of sio is never larger than 65535. If sio is 65535, its value is reset to 0 when the next start I/O operation takes place.

device_address is the hexadecimal address of the channel-attached device. This field contains *NA if the device address is not available.

SLOWDOWN=YES, if present, indicates that the node is in slowdown.
