RAMP SOAK BLOCK

3-16

33

Bad Track Input (BADTRK) ............................................................................................... CWR
See Section 2.3.2, Data Quality for additional information.

REJECTED

0

The track input quality is checked if Bad Track Input Accepted
attribute is False. If it is False and the track input quality is bad, then
the ramp soak block does not update its outputs and the output
qualities are set bad.

ACCEPTED

1

Block runs its algorithm without a check on input quality and output
quality is set to good.

NOTE: This parameter is required to eliminate a bad quality latch up problem. Since the ramp

soak result is connected to the remote setpoint of the PID, if the result quality goes
bad then the adjusted remote setpoint quality is set bad. The adjusted remote setpoint
is connected to the ramp soak track input. Therefore, the Bad Track Input Accepted
attribute should be set to TRUE when connected to the PID as described.

34

Process Input (PROCINP) ................................................................................................ CWR
Process Input floating point value that ramp soak profile Result is being compared to and
controlled by.

local data

0

The initial local data value is 0.0.

source pointer

Any floating point source. Specify remote data by making a
connection to this block attribute. If a connection exists, the input is
considered remote, even if local data has been specified.

35

Track Input (TRKINP) ........................................................................................................ CWR
When in TRACK, the Result is set to the Track Input value.

local data

0

The initial local data value is 0.0.

source pointer

Any floating point source.

36

Track Command Input (TCMDINP) .................................................................................. CWR
When the Track Command Input is TRUE the Result will always be set to the value of the
Track Input and the Mode will be TRACK. When the Track Command Input goes to FALSE
the Mode will be RUN or HOLD determined by the Return Mode attribute.

NONE

No Track Command input configured. Attribute is not used.

local data

0

The initial local data value is FALSE (0). If the value is true the mode
status will be TRACK.

source pointer

Any discrete source.

37

Reset Input (RESINP)........................................................................................................ CWR
A FALSE to TRUE transition resets the profile to segment 1 and the mode to RUN.

NONE

No Reset input configured. Attribute is not used.

local data

0

The initial local data value is FALSE (0).

source pointer

Any discrete source.
