Setpoint: To set up the process value for actuating Job1 and /or Job2

Job1, Job2: When an event occurs, the task to be performed is called the job. A typical example is to trigger an alarm buzzer in event of high temperature. Each pen can accept four events ( or alarms ) and each event can create two jobs. Please note that a job under Event is different from a job by pressing the Operate key. The former is actuated by an event, and the latter is actuated by manual control, no event necessary.

Various types of jobs can be selected:

No Action: Do nothing.

Log Alarm: Record alarms

Log Event: Record events

Sound Buzzer: Sound the buzzer. It stops once any key is pressed.

DO Latch On: Set digital output / relay on, and then select Target from DO 1 to DO 6. The relay is latched when it is activated.

DO Latch Off: Set digital output / relay off, and then select Target from DO 1 to DO 6. The relay is latched when it is activated.

DO Process: Set digital output / relay on for process high or low, and then select Target from DO 1 to DO 6. The relay is not going to be latched when it is activated.

Enable Timer: Start the timer, and then select Target from Timer 1 to Timer 6.

Disable Timer: Stop the timer, and then select Target from Timer 1 to Timer 6.

Preset Totalz: Start the totalizer with a preset value, then select Target from Tolz 1 to Tolz 6.

Reset Totalz: Reset totalizer into zero, and then select Target from Tolz 1 to Tolz 6.

Enable Totalz: Start the totalizer, then select Target from Tolz 1 to Tolz 6.

Disable Totalz: Stop the totalizer, then select Target from Tolz 1 to Tolz 6.

Preset Counter: Start the Counter with a preset value, then select Target from Cont1 to Cont6.

Reset Counter: Resets the counter into zero, and then select Target from Cont1 to Cont6.

Inc Counter: Increase the counter, and then select Target from Cont1 to Cont6.

Dec Counter: Decrease the counter, and then select Target from Cont1 to Cont6.

Log Report: Make the report for Counter and Totalizer. Choose this column, and then the report will be presented as details described in 3.4 Event.

Note:

The sampling rate of the recorder is fixed at 200 milli seconds by the hardware. i.e. samples 5 measured data per second.. If the logging speed is set at 1 second in Instant mode, the recorder logs using the last of five measured data values. For the same speed in Averaging mode, the recorder logs using the average of the five measured data values. For the same speed in the Maximum or Minimum mode, then the recorder logs using the maximum or minimum of the five measured data values..
