PROline Prosonic Flow 93 FOUNDATION Fieldbus 3 Transducer Blocks (transmission blocks)
Endress+Hauser 157
System -
Alarm Delay
AUTO - OOS Use this parameter to define a time span for which the criteria for
an error have to be satisfied without interruption before an error or
notice message is generated.
Note!
Depending on the setting and type of error, this alarm delay acts
on both the display and the output values of the FOUNDATION
Fieldbus.
User input:
0...100 s (in steps of one second)
Factory setting:
0 s
Caution!
If this parameter is used, error and notice messages are delayed
by the time corresponding to the setting before being forwarded to
downstream function blocks or the fieldbus host system.
It is therefore imperative to check in advance whether a delay of
this nature could affect the safety requirements of the process. If
fault and notice messages may not be suppressed, a value of 0
seconds must be entered here.
System -
Simulation
Failsafe Mode
AUTO - OOS Use this function to set the totalizers to their defined failsafe
modes, in order to check whether they respond correctly.
The totalizers' response to faults is defined via the "Totalizer
Handling - Failsafe All" parameter, (see Page 155).
Note!
With regard to the fieldbus, an active simulation is relayed to
downstream function blocks or higher-level process control
systems by means of the status “UNCERTAIN” for the output value
OUT (AI Block).
Options:
OFF

System - Reset AUTO - OOS Use this parameter to perform a reset of the measuring system.

NO
RESTART SYSTEM (restart without interrupting power supply)
