7.8.1
Using a digital output for scan synchronization signals
One digital output can be configured to provide a scan synchronization signal. The
signal is set to while the measuring laser is active during a scan. The signal is
cleared during the idle period between two scans.
Only one digital output can be used for the synchronization signal. SW1 will be
used while a second synchronization output remains inactive.
The feature is set active by setting the parameter “SW function” to “1=scan sync”:
SW function: 0=off, 1=scan sync, 2=switch, 3=counter
7.8.2
Setting the status of a digital switching output
The state of the digital switching outputs can be set by software. This allows a
control computer to signal application depending status information to another
system.
The feature is set active by setting the parameter “SW function” to “2=switch”.
The open/closed status of the output is set by the user parameter:
SW status: 0=open, 1=closed
7.8.3
Using the digital switching outputs as preset counters
User applications can set a counter value in advance to produce output signals of
a specific count.
This function permits a control computer to transmit a counting stand or volume
information as digital signals to another system. All digital switching outputs can
be used independently. The preset counter feature is set active by setting the user
parameter “SW function” must be set to “3=counter”.
The counter value must be written to the parameter
SW preset counter: setup
The sensor firmware copies this value, sets the parameter register back to 0, and
starts the count down. After this, new counts can be added to current output by
writing another counter value. Make sure that the parameter “
SW preset
counter setup
” has reached 0 before adding new counts.
The hold time can be defined by the user parameter
