Behavior of the digital outputs of the bar code scanner with “Fieldbus input” reading cycle source
The digital outputs can be configured so that the outputs show information from other
network nodes (e.g., external output 1=fieldbus input).
If the fieldbus is interrupted, these outputs are no longer updated. The outputs will then
each retain the last value before the interruption.
After switching on the fieldbus (power-up), all digital outputs are set to their “passive”
values.
Status of digital outputs with
output value behavior
IOPS = Bad
Retain the last value before cancellation
Connection lost
Retain the last value before cancellation
Switching on the PROFINET network
Values are initialized to “passive”
The reading cycle input can also be controlled by the fieldbus. When the fieldbus is
interrupted, the reading cycle input is no longer updated. Reading results may then get
lost since the reading cycle input retains its last value before the interruption.
After switching on the fieldbus (power-up), the reading cycle input is set to its “passive”
value.

Configuration of the device using command strings
As an alternative to the SOPAS ET configuration software, the device can also be
configured with command strings via all data interfaces. Functions in the device can
also be triggered. The command strings can be displayed individually in the SOPAS ET
configuration software.
NOTE
Both the command strings and the SOPAS ET configuration software are based on a
command language that has direct access to the command interpreter of the device.
This command language must be used with care, as the commands sent to the device
are carried out immediately.
Parameter values modified by means of commands are initially only active in the
current parameter set in the volatile working memory of the device.
To ensure that modified parameter values are not lost, copy the parameter set to the
permanent memory. This needs to be done using a special command before switching
off the supply voltage.
Command strings for triggering the read pulse:
•
START: <STX>sMN mTCgateon<ETX>
•
STOP: <STX>sMN mTCgateoff<ETX>
When the commands are entered via the terminal emulator of the SOPAS ET configura‐
tion software, both control characters <STX> and <ETX> are omitted.
An overview of command strings for the device is available on request
