3.6.4 QAS – Event list query
Sening®
Innovative Tank Truck Systems
The QAS node (Quality Assurance System) accesses the NoMix- und MultiSeal data. Events are
saved in an internal logbook in both devices (NoMix, MultiSeal). Several thousand saveable events
in the QAS device precludes the output being undertaken in a telegram. That is why every event is
transmitted in a REPORT telegram. A special structure is defined to represent the events.
Event-Struktur:
QAS
EVENT
Type Event-Typ
Value1 1. Parameter for this Event-Typs
Value2 2. Parameter for this Event-Typs
Date Date for this Events (DD.MM.CCYY)
Time Time fort this Events (hh:mm:ss)
Special features:
� In addition to the usual and characters for confirming receipt of correct
telegrams or for refusing faulty telegrams respectively, an additional control character,
, is used, with which the transmission of further events can be halted.
� Before a further telegram is outputted, the OBC is to answer every REPORT telegram with
an , or .
� Should the OBC answer an “EVENT report line“ with a NAK, then this line is to be repeated
for as long as NAKs are transmitted as an answer. It is up to the OBC software to decide
whether the report line is to be re-requested or the tranmsission stopped by a CAN.
� From Log Version 2.0 onwards signals the end of a data transmission.
� EMIS alternatively sends and when lengthy interruptions (up to 2
minutes) arise. This happens, for instance, when event information is analysed at the
beginning of the query.
� In contrast to all the other variables, the EVENT structure ones cannot be individually
inquired into.
� The setup parameters are always transmitted by default at the start of the event query. This
can be stopped by setting the variable QAS,SETUP,NoSeP=1. The setup parameters are
always outputted on the recalling of the events with date/time.
� The NoSep variable retains its value even after a power-off.
� Setting the QAS,SETUP,ReInit variable with any value etsablishes the ongoing time as the
starting time for the next event query.
� Inquiring into the event without date / time has the effect of stopping SCU events (see 4.2.1.3
Event Table / Page 33) being saved in the QAS log book.
� If the OBC does not answer an “EVENT report line“ with an , then the ouput is
interrupted for as long as it takes for an to be accepted.
