10.2 Error Codes 10.2.1 Checking the error code
*1 If an error that occurs simultaneously with a network error is selected, the status just before the error occurrence may be
displayed in intelligent module information.
● If errors have occurred frequently in the CC-Link IE Controller Network module, "*HST.LOSS*" may be displayed in the
"Error Code" column, instead of an error code.
If "*HST.LOSS*" appears frequently, increase the number of module errors collected per scan in "PLC RAS" of "PLC
Parameter".
For the setting, refer to the following.
User's Manual (Function Explanation, Program Fundamentals) for the CPU module used.
● If the same error code has occurred continuously, only the first error record is displayed in the "Error History" window.
However, for dedicate instructions, if an instruction name or a channel number is different, an error code is displayed
even when the same error code has occurred continuously.
Item Description
Error history list
The error history of the module is displayed.
If an error occurs during initial processing of a programmable controller CPU,
"0000/00/00 12:00:00 AM" is displayed as an error occurrence date and time. This
error is not displayed in order of actual error occurrence date and time in the error
history list. (Example: Reserved own station error, etc.)
Error and Solution Displays details and actions of an error selected in "Error History List".
Intelligent Module Information
Displays the status of the CC-Link IE Controller Network module at the time when an
error selected in "Error History List" occurs.
*1
Baton pass status (own station) (SW0047) Displays the baton pass status of own station.
Cause of baton pass interruption (SW0048) Displays the cause of baton pass interruption of own station.
Cause of data link stop (SW0049) Displays the cause of data link stop of own station.
IN-side loopback station No. (SW0070)
Displays the station No. of the station where a loopback is executed at forward loop
side.
OUT-side loopback station No. (SW0080)
Displays the station No. of the station where a loopback is executed at reverse loop
side.
Baton pass status of each station (SW00A0 to
SW00A7)
Displays the baton pass status of each station.
0: Baton pass normally operating station
1: Baton pass faulty station
Name of dedicated instruction where an error
occurs
Displays the name of dedicated instruction where an error occurs.
Dedicated instruction CH where an error occurs Displays the channel number of dedicated instruction where an error occurs.
Target network No. where an error occurs Displays the target network No. of dedicated instruction where an error occurs.
Target station where an error occurs Displays the target network No. of dedicated instruction where an error occurs.
