94 Mode Model (MM) ..............................................................................................................C – R
The mode model specifies whether Output and Setpoint Mode are manipulated independently,
or in combination as subordinate to the Controller Mode attribute. The mode model states
are:
SP/OP MODE 0 Setpoint/Output Mode.
CTRL MODE 1 Controller Mode. A Remote Setpoint Input must also be configured.
The following occurs when using the configurator to change to CTRL MODE:
•
Allowed Modes (Setpoint, Controller, Output) are set to L.R, M.A, and M.A.C.
•
Controller Mode and Restart Controller Mode are set to MANUAL.
•
Output Mode and Restart Output Mode are set to MANUAL.
•
Setpoint Mode and Restart Setpoint Mode are set to LOCAL.
While in the CTRL MODE, the Setpoint and Output Modes, Setpoint and Output Restart
Modes, and Setpoint and Output Allowed Modes may not be entered by the user. Setpoint
and Output Modes take on values based on the user entered value for Controller Mode.
Similarly, Setpoint and Output Restart Modes take on values based on the user entered value
for Restart Controller Mode. These values are:
Controller Mode Output Mode Setpoint Mode
CASCADE AUTO REMOTE
AUTO AUTO LOCAL
MANUAL MANUAL Don't Care
TRACK TRACK Don't Care
If the mode model state is set to SP/OP MODE, then the Controller mode, Allowed Controller
Modes and Restart Controller Mode are set to N/A by the configurator. While the mode model
is SP/OP MODE, the Controller Mode, Allowed Controller Modes and Restart Controller Mode
cannot be set by the user.
100 Input Filter Type (FILTYPE) .............................................................................................. CWR
The input filter type allows selection of a user low pass filter time constant, a default calculated
value or no low pass filter.
NONE 0 No low pass filter is used. The last sampled value is the
input value.
PREACT,AUTO 1 The Preact Auto type filter type calculates a default low pass
filter time constant based on derivative time and the task
execution rate.
PREACT,USER 2 A user configured input filter time constant (FILTIME) in
minutes is used in the filter calculation. The filter is applied to
the derivative (on process or error) signal before being used
in the PID algorithm.
PROCESS,USER 3 A user configured input filter time constant (FILTIME) in
minutes is used in the filter calculation. The filter is applied to
the process (on process or error) signal before being used in
the PID algorithm.
