6 PID function block (PID controller) PROline Prosonic Flow 93 FOUNDATION Fieldbus
214 Endress+Hauser
ROUT_IN ROUT - RCAS -
CAS - AUTO -
MAN - OOS
In this parameter, the manipulated variable (value and status)
provided by the fieldbus host system is read in and displayed.
Note!
• Value statement and unit of OUT_SCALE
• This parameter is only active in the ROUT operating mode.
• The PID algorithm is no longer executed.
ROUT_OUT read only Displays the analog output value and status of the manipulated
variable transferred to the fieldbus host system in the course of
cascade control. The cascade control is initialised with this value
to ensure bumpless switching of the operating mode.
Note!
• Value statement and unit of OUT_SCALE
• This parameter is only active in the ROUT operating mode.
SHED_OPT Selects the action taken if the monitoring time is exceeded (see
SHED_RCAS, SHED_ROUT parameters on Page 96) in the RCAS
or ROUT operating mode.
During the monitoring time, parameter updating between the
fieldbus host system and the PID function block is checked.
If the parameters are not being updated then on expiry of the
monitoring time the PID function block switches from the RCAS or
ROUT operating mode to the mode selected here.
