Events - Honeywell DCP551 Mark ΙΙ User Manual

Events

Time events
The event configuration data setting allows event types to be set for event outputs 1 to 16.
Events are of the following four types: time event, PV event, code event and mode
event. Settings are divided into two types of events: segment events and instrument
event.
• Segment events are used to set the event operating point in a program setting and
makes it possible to set different set values in different segments. But in the constant
value control mode segment events are off.
• Instrument events are used to set events that do not require an event operating point
or set the event operating point in the event configuration setting. It performs opera-
tions that are shared by all program operations and constant value control.
The On Time or both the On and Off Time can be set by event number and segment.
Output on/off duration are as shown below.
NOTE
• The On Time is indicated by the length of the line from the start of the segment
until the upturned arrow.
• The Off Time is indicated by the length of the line from the start of the segment
until the downturned arrow.
• When the On Time is less than the off time, the output is on from the on time until the
off time.
(See segments 1, 6 and 7 in the figure.)
