The disconnected station is displayed in the position where it was connected
when operated normally.
1) Conditions and timing for normal connection information acquisition
When all of the following conditions are met, the normal connection information
is stored in the CC-Link IE Controller Network module.
• All stations are in data link status. (Cyclic transmission status of each
station (SB00B0) is OFF.)
• No station is loopbacked. (Loopback status (SB0065) is OFF.)
• No station has a parameter error. (Parameter status of each station
(SB00E0) is OFF.)
• The number of actually connected stations is the same as the total
number of stations (except for reserved stations) set on the control station.
After any of the above conditions was not met, if all the conditions are met
again, the normal connection information will be updated.
POINT
(1) After acquisition of the normal connection information, if the network
configuration is changed with a cable or station disconnected, the changed
network configuration cannot be displayed correctly.
Update the normal connection information by the following.
(If the network has an error, however, the normal connection information
cannot be obtained. Therefore, the screen display is as in the case where the
normal connection information has not been obtained.)
• Power OFF and then ON or reset the connected station.
• Take corrective actions to set all stations into normal state.
(2) If a station that is not included in the normal connection information is added,
the station is displayed on the IN side of the connected station.
*1
For acquisition of the normal connection information, there are restrictions on the version of the
CC-Link IE Controller Network module on the connected station.
Check the version of the CC-Link IE Controller Network module.
