A-102 QX Hawk Industrial Imager User Manual
Using EtherNet/IP
Note the following details with “In Read Cycle” and “Actively Scanning” signals:
1. They may be very short-lived. It is possible for the imager to begin and end a read
cycle without these signals being seen in active state.
2. They are only valid for normal read cycle operation: continuous, serial, and triggered.
They do not reflect operation during bar code configuration, read rate, auto-calibration,
or ESP “Setup” mode.
Read Cycle Sequence Counter
When this value changes, it indicates a new read cycle report is present.
Read cycle report data is only valid when Sequence is not 0.
Read cycle reports are only output during normal read cycles: continuous, serial, and
triggered. Read cycle reports are not output during bar code configuration, read rate,
auto-calibration, or ESP “Setup” mode.
Read Cycle Report: Trigger, Decode/Match, Mismatch, No Read Count
These are the historical read cycle result counters. By comparing the values to a previous
report, the number of decodes, mismatches and noreads in the current read cycle can be
determined.
Read Cycle Report: Decode Data
This string has the same format that would be output a serial port or tcp connection, with
one difference: preamble and postamble are not
added.
QX Hawk OUT Assembly 0xC6, 198 decimal: Command (OUT= PLC ->
QX Hawk)
User Defined Tag
This provides the PLC programmer a method of uniquely identifying multiple imagers in
the system. This field serves no functional purpose in the QX Hawk. The value sent by the
PLC for this field is echoed back to the input assemblies.
