2.5.2.6 Summary
2.5.3 Events and signals output
2.5.3.1 Check cycle signals
The Not_measuring signal is active during the check cycle.
This signal can be sent via a digital output or read out via the OPC interface.
2.5.3.2 Maintenance request signal
The Maintenance_request signal is activated when an unallowed drift is determined or the
NO cell is empty
 p. 13, §2.5.2) and, at the same time, an appropriate message entered in
the Logbook. The Maintenance_request signal can be sent via a digital output or read out
via the OPC interface.
2.5.3.3 Zero and reference point level output
The zero and reference point values determined can be output via the analog outputs. This
is done - depending on the parameter settings - directly after the check cycle or on demand
(via a digital input). The Output_control_values signal is active during output and can also
be sent via a digital output. The zero values are first output for 90 s and then the reference
values for 90 s. The Not_measuring signal is not active during the output.
As an alternative, the zero and reference values of the last check cycle can be read out
using SOPAS ET menu /Diagnosis/Check cycle.
