EXAMPLE 4

Operator Messages

Operator Messages are user defined messages to advise, or provide information, via the display, that selected actuators are active. The messages are displayed as specified by the Operator Message Display Mode parameter setting.

Application:

A user would like a visual indication whenever the total exceeds the preset along with instructions for an operator.

Configuration:

 

Operator Message:

OM1 DISPLAY Mode*

PREEMPT TO OFF

*PREEMPT TO OFF - Specifies that the message overrides the display of values until any key is pressed, after which it will not appear until the actuator goes inactive then active again.

EXAMPLE 5

Chart Messages

Chart Messages allow user defined text, up to 4 values, and a time/date stamp to be recorded on the chart, triggered on the transition of an actuator, not its state. The message can be one to six lines with missing lines causing the remaining line to be moved up. The message is recorded on the six outermost "lines" within the trend area. Trend and time lines will not be overwritten or lost.

Since it may take considerable time for the instrument to record a message, three messages will be queued with a fourth queue providing a QUEUE OVERFLOW message. All messages actuated while the queue is full are lost.

Application:

A user would like to print a message indicating that Alarm 1 on Process Value 2 has tripped.

Configuration:

 

Chart Message:

Operation:

During Normal Operation, if the pressure exceeds the alarm setpoint, the alarm (A21) will go on and at the same time the actuator, A21, will trigger the chart message, ALARM 1 PRESSURE HI, and print the value of IV2, the actual pressure, and PV2, the process value used to trigger the alarm.
