TROUBLESHOOTING
This chapter describes details on various errors that occur in use of the Camera recording package, and determined causes
and actions for those errors.
When the FB ends with an error
■When the error code C1B1H is output
Item to check
In the programmable controller settings,
check whether the constant scan time
exceeding 500ms is set.
■When the error code 1128H or 112EH is output in the connection with the MELSEC iQ-R series
module
Item to check
Check the settings of the specified
connection number.
Check the connection between the network
camera and the module.
Check if multiple FBs are simultaneously
executed.
■When the error code 41B9H or 41A6H is output in the connection with the MELSEC-Q series
module
Item to check
Check the settings for the specified
connection number.
Check if multiple FBs are simultaneously
executed.
■When any error code from C1E0H to C1E3H is output
Refer to the list of error codes for each FB.
■When an error code other than the above is output
Refer to the following:
 MELSEC iQ-R Ethernet User's Manual (Application)
 QCPU User's Manual (Hardware Design, Maintenance and Inspection)
When the time of the programmable controller cannot be set to the network camera
Item to check
In the configuration tool of the network
camera, check whether the "Date and time"
window is activated.
When no video file can be saved in the network storage
Item to check
Check whether the FB is executed with the
virtual input port number for which no
recording event is set.
Check whether the virtual input port status is
enabled by the FB while the virtual input port
status on the network camera side has
already been enabled.
Check whether the recording is ongoing on
the network camera side.

Action and cause
After setting the constant scan time to 500ms or lower or leaving it blank, execute the FB again.
If the constant scan time exceeds 500ms, the socket communications are disconnected by the network camera
operation and data communications is disabled.
Action and cause
Check "External Device Configuration" for the settings of the connection number.
There may be an error in the settings.
Check the wiring. When connecting the network camera to the RJ71EN71 or RnENCPU, check whether the
correct Ethernet port is used.
The network camera may be connected incorrectly.
Check the program.
Multiple FBs may be simultaneously executed to a single network camera.
Action and cause
Check "Open Setting" for the settings of the connection number.
There may be an error in the settings.
Check the program.
Multiple FBs may be simultaneously executed to a single network camera.
Action and cause
After closing the configuration tool of the network camera, execute the FB again.
The FB side operates normally when the time setting in the configuration tool on the network camera side is
being edited, but the time of the programmable controller is not reflected on the network camera side.
Action and cause
Set the virtual input port set for the recording event to the same number as the virtual input port set for the FB.
The virtual input port status on the network camera side becomes enabled/disabled and the FB side operates
normally. However, since no recording event is assigned to the network camera side, no event occurs.
Restart the network camera, or disable the virtual input port status on the network camera side by the FB
before execution.
Since the virtual input port status on the network camera side has already been enabled, no event occurs.
When the recording time (seconds) after the occurrence of the recording event has ended, execute the
command send.
When the recording is ongoing on the network camera side during the command send, no event occurs.
