14.1.6
Behavior of the switching outputs of the bar code scanner with “Fieldbus input” reading cycle
source
The digital outputs can be configured so that they can show information from other net‐
work participants (e.g. external output 1 = fieldbus input).
In the event that a fieldbus is interrupted, these outputs are no longer updated and
keep the last value that existed 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
Contain the last value before cancellation
Connection lost
Contain 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. If the fieldbus is inter‐
rupted, the reading cycle input is no longer updated. Reading results can get lost since
the reading cycle input keeps the last value from before the interruption.
After switching on the fieldbus (power-up), the reading cycle input is set to its “passive”
value.
14.2
Configuration of the device using command strings
As an alternative to the SOPAS ET configuration software, the device can also be config‐
ured, and functions can be triggered in the device, with command strings via all data
interfaces. The command strings can be displayed individually in the SOPAS ET configu‐
ration software.
NOTICE
Both the command strings and the SOPAS ET configuration software are based on a
command language that has direct access to the device command interpreter. This
command language must be used with care, as the commands sent to the device are
carried out immediately. Parameter values altered by commands are initially only active
in the current parameter set in the volatile working memory of the device. For perma‐
nent storage, the altered parameter set must be copied with a special command into
the permanent store, so that the alteration is not lost when the supply voltage is
switched off.
Command strings for triggering the read pulse:
b
START: <STX>sMN mTCgateon<ETX>
b
STOP: <STX>sMN mTCgateoff<ETX>
If the commands are entered via the terminal emulator of the SOPAS ET configuration
software, both control characters <STX> and <ETX> are omitted.
