PROCESS FLOW PROGRAMMING
A cyclic measuring point scan with a time-based process flow control is
required to register the measuring data of all connected sensors. For this
purpose, the real time clock, the print cycle and the measuring cycle are
available and, if fast processing is required, the conversion rate is available.
The measurement can be started and stopped by using the keyboard, the
interface, an external trigger signal, the real time clock or an exceeding of limit
values.
Time and Date
The real time clock with date function or the pure measuring time are used for
an accurate recording of any measurement. Start and end time/date can be
programmed in order to start or stop a measurement.
Print Cycle
The print cycle is also programmable between 1s and 59h/59min/59s and
provides a cyclic output of measured values to the interfaces or memories and
also provides a cyclic averaging.
Print Cycle Factor
If necessary, the print cycle factor allows for limiting the data output of
particular channels so that an excessive data flow can be limited, especially
during data storage.
Measuring Cycle
The measuring cycle, also programmable between 1s and 59h/59min/59s, is
for a cyclic scanning with a display of all measured values, limit value
monitoring including alarm message and output of alarm values, averaging
and, if necessary, a storage of measured values.
Average Value
The measured values resulting from scanning the measuring junctions can be
averaged as desired either over the total measuring time or over the print cycle
time. Function channels are provided for a cyclic output of average values.
Conversion Rate
With ALMEMO
®
V5
devices, all measuring points can be continuously
scanned with the conversion rate (2.5 or 10 meas./s). It is possible to store all
measured values in the memory and/or to perform an output via the interface.
Storage of Measured Values
During the measuring or print cycle, all measured values or alarm values can
be manually or automatically stored in a buffered RAM. The memory capacity
is, as standard, 500kB, which allows up to 100,000 measured values. The
memory organisation can be configured as linear or ring memory. Alernativ are
usably also memory connectors. The output can be optionally performed via
interface, analogue output or display. It is possible to select a certain time
interval, number or alarm value.
