PROline Prosonic Flow 93 FOUNDATION Fieldbus
Description
Displays the discrete output value and the status of the Discrete
Output function block.


Note!
If MAN (manual) is selected for the operating mode in the
MODE_BLK parameter then the output value OUT_D can be
specified manually here.
Displays the discrete process variable value and status
determined in the READBACK_D parameter.
In this parameter, the fieldbus host system can store a reference
to a description of the possible states of the PV_D parameter.


Note!
This parameter is not evaluated by PROline Prosonic Flow 93
FOUNDATION Fieldbus.
In this parameter, the discrete setpoint value (value and status)
provided externally, (fieldbus host system, other function block
etc.), is read in for internal calculation and displayed.


Note!
This parameter is only active in the RCAS operating mode.
Displays the discrete output value and status of the specified
setpoint value transferred to the fieldbus host system in the
course of cascade control.


Note!
This parameter is only active in the RCAS operating mode.
Displays the input signal condition and status of the feedback
message input.
Selects the action taken if the monitoring time is exceeded, (see
SHED_RCAS parameter, Page 96) in the RCAS operating mode.
During the monitoring time, parameter updating between the
fieldbus host system and the Discrete Output function block is
checked.
If the parameters are not being updated then on expiry of the
monitoring time the Discrete Output function block switches from
the RCAS operating mode to the mode selected here.
