Digital Output
Each of DO1 to DO3 can be assigned the following functions (events). The functions are
divided into two categories for when they behave as alarms and when they behave as events.
1. DO event settings
Events are divided into those related to alarms and those not related.
For more about the events related to alarms, see "11. Alarm Action Type Codes" (page 18).
Use the following steps events other than alarms.
●
Ramp soak delay start
●
Wire burnout circuit alarm
●
Conditional outputs
Use the following steps to set DO.
2. Setting DO option functions
Allows you to set not just even settings, but option functions for each DO.
The DO events are set by each digit.
3. Setting the alarm menu
●
Hysteresis Function
The hysteresis band is preserved during alarm output.
●
Delay Function
When events (including alarms) occur, the DO does not begin outputting immediately.
Instead, the event continues for a specified period of time before outputting DO.
This is called a delay function because there is a delay between the event and outputting to
DO.
Use the following steps to set an alarm delay and hysteresis.
4. Setting the operation menu
Sets the alarm value so that DO is used as the alarm output.
Use the following steps to set this function.
