*1 The possible reasons include that the slave station set in parameter has not started up, a cable between the master station and the
slave station is disconnected, or the setting of an IP address or a subnet mask of the master/slave station is incorrect.
*2 Take actions and eliminate the error cause first. Then, clear the error code.
*3 When the count exceeds 65535, counting is continued from 1 again.
*4 For details on an error of the slave station, GX Works3 of "1.040S" or later supports. (Page 58 Added and Enhanced Functions)

The following indicates that the disconnection has occurred due to no cyclic transmission caused by the cable
disconnection of the master station side. In this case, the previous cyclic transmission time (just before the
disconnection) is displayed on the link scan time.
• "CFE8" is displayed as the latest error for all slave stations. (No response received from a slave station)
• "No Error" is displayed on the error code of the master station.

The IP address of the master station is displayed. The display can be switched between decimals and hexadecimals in
"Change IP Address Display".
The error code of the master station is displayed.
The description of the error and the actions to be taken are displayed.
Link scan time (present, maximum, minimum) and number of error stations/unfixed stations of each group is displayed.
Error stations (Error Stns) and unfixed stations (Unfixed Stns) refers the following state.
• Error Stns: Stations where an error has been occurred
• Unfixed Stns: Stations (not including reserved stations) where the transmission status has not been fixed
Select a group to display its diagnostic information list.
The station number of the slave station is displayed.
The number of occupied stations set in parameter is displayed.
The reserved station status set in parameter is displayed.
The IP address set in parameter is displayed.
"-" is displayed when the station is a reserved station and an IP address has not been set.
The transmission status of the slave station is displayed.
• Unfixed: Communications with the master station not established
• Transmitting: Cyclic transmission being performed
• Disconnecting: Disconnected from the master station
The accumulated number of disconnection detection is displayed.
• 0: No disconnections
• 1 to 65535: Number of disconnection detection (accumulated number)
The accumulated number of timeouts is displayed.

The latest error code is displayed an error on the transmission status between the master station and slave stations
detected by the master station or an error which has occurred in a slave station. When the slave station is
disconnected, an error occurs. After that, even when the disconnected slave station returns to the system, the error is
held. When another error occurs, the latest error will be updated (overwritten).
When both errors occur, the priority of errors to be displayed is as follows.
(1) An error which has occurred in a slave station
(2) An error on the transmission status between the master station and slave stations detected by the master station
For an error of the slave station, check 'Diagnostic information 2' (Un\G1068 to Un\G1077). ( Page 48 Acquiring
