Table 3.13 AnaWin3 Output Types
Heat/Cool Cycle Time
Specify the time base for time proportional outputs. The output
percentage is proportioned over this time period. For example,
a 50% output with a 10-second cycle time is on for 5 seconds and
off for 5 seconds. Heat/Cool Cycle Time only affects control when
the corresponding output type is set to Time Prop (digital time
proportioning).
Range: 0 to 255 seconds
Heat/Cool Curve
Indicate which output scaling method is to be used.
• Straight Linear — Output is unaffected and is set as
calculated by the closed-loop PID calculation.
• Lag Curve A — Output is reduced somewhat from calculated
value.
• Lag Curve B — Output is further reduced from calculated
value.
Straight linear is used for most applications. Lag curves are
usually used in plastic extruder applications.
Output Type Description Function
Time Prop digital, time proportioned
Percent output converted to a percent duty
cycle over the user-selected fixed time.
DZC
digital, distributed zero crossing
(not available for mechanical relay outputs) Output on/off state calculated for every AC
line cycle.
On/Off digital, on/off Output either full ON or full OFF
Internal Count Integer register
Calculated output may be used by a logic
program
