Chapter 5. FUNCTIONS

■Events

First, setup data setting C64 is used to assign CH1 and CH2 events, then the event configuration data setting is used to set event types 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 operations that are shared by all program operations and constant value control.

●Time events

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.)
