Chapter14 Analog Output Module (XBF-DV04C/XBF-DC04C)
14.6.3 Disconnection detecting function
(Only for current output module XBF-DC04C)
If the analog current output module detects disconnection of output, it can show the status of
module.
In case that the module checks the disconnection and it is shown as the disconnection status,
there are faulty in parts of wiring connection paths. Please check and take action.
1) In case that the disconnection between used output wiring and module is caused, LED
can flicker 1s intervals and make an error flag.
2) The disconnection can be detected per each channel only for designed channels for
operation. LED can use from channel 0 to 3 in common.
If the one channel or more is disconnected, flickering will be generated.
