10.3.2 Control of the decoding
In general, decoding is controlled via one or more of the configurable switching inputs/outputs. For this
purpose, the respective connection to the SW IN/OUT and POWER interfaces must be configured as a
switching input.
Via a switching input, you can:
• Start decoding
• Stop decoding
• Start decoding and then stop decoding after a configurable time period
• Read a reference code
• Start the automatic code type configuration (AutoConfig)
Connect the required control devices (photoelectric sensor, proximity switch, etc.) as described in
Chapter 7 to the BCL 300
i
\ BCL 301

.
Configure the connected switching inputs according to your requirements. To do this, first set the
I/O
mode
to
Input
and then configure the switching behavior:
• Via webConfig:
Configuration > Device > Switching inputs/outputs
Advanced decoder control via the webConfig tool
The webConfig tool provides advanced functions, in particular for deactivating decoding. These may be
accessed via the
Control
submenu of the
Configuration
main menu. You can:
• Activate decoding automatically (delayed)
• Stop decoding after a maximum reading gate time
• Stop decoding via the completeness mode, if:
• The maximum number of bar codes to be decoded has been decoded
• A positive reference code comparison has taken place.
10.3.3 Control of the switching outputs
By using the switching inputs/outputs of the BCL 300
i
\ BCL 301
i
, external event-controlled functions can
be implemented without assistance from the superior process control. For this purpose, the respective
connection at the SW IN/OUT and POWER interfaces must be configured as a switching output.
A switching output can be activated:
• At the start/end of the reading gate
• Depending on the read result:
• Reference code comparison positive/negative
• Read result valid/invalid
• Depending on the state of the device:
• Ready/not ready
• Data transmission active/not active
• Active/standby
• Error/no error
• etc.
As described in Chapter 7 of the manual, connect the required switching outputs.
Configure the connected switching outputs according to your requirements. To do this, first set the
I/O
mode
to
Output
and then configure the switching behavior:
• Via webConfig:
Configuration > Device > Switching inputs/outputs
NOTE
Alternatively, one can also activate decoding via the online command ’+’ and deactivate it via the
online command ’-’. Further information on the online commands can be found in Chapter 11.
