4.4 Scan Operation
Scanning is started by the SCAN signal of EXT. I/O or the communication
*
TRG
command. The scan
channel is moved forward by the SCAN signal or the
*
TRG
command.
When the channel is the final channel, scanning is completed by the SCAN signal or the
*
TRG
command,
and all relay is opened and goes back to the beginning of the scan list. Note that scan operation will not
complete until another SCAN signal or
*
TRG
command is input in the final channel state.
