Defining Events - Emerson Micro-Motion 2400S Configuration And Use Manual

Optional Configuration
Additionally, if your transmitter has a discrete output, you can configure a discrete output so that it is
active if the event is ON, and inactive if the event is OFF (see Section 6.7). For example, the discrete
output can open or close a valve according to event status.
8.7.1

Defining events

To define an event:
• Using ProLink II, see Figure C-3.
• Using the Communicator, see Figure C-9.
The following general steps are required:
1. Select the event to define.
2. Specify the Event Type. Event Type options are defined in Table 8-5.
Table 8-5 Event types
Type Description
High (> A) Default. Discrete event will occur if the assigned variable is greater than the setpoint (A).
Low (< A) Discrete event will occur if the assigned variable is less than the setpoint (A).
In Range Discrete event will occur if the assigned variable is greater than or equal to the low setpoint (A) and less
than or equal to the high setpoint (B).
Out of Range Discrete event will occur if the assigned variable is less than or equal to the low setpoint (A) or greater
than or equal to the high setpoint (B).
(1) An event does not occur if the assigned variable is equal to the setpoint.
(2) An event occurs if the assigned variable is equal to the setpoint.
3. Assign a process variable to the event.
4. Specify the event's setpoint(s) – the value(s) at which the event will occur or switch state (ON
to OFF, or vice versa).
• If Event Type is High or Low, only one setpoint is used.
• If Event Type is In Range or Out of Range, two setpoints are required.
Note: If a mass or volume total has been assigned to Event 1 or Event 2 and also configured as a
display variable, the event type is High or Low, and the transmitter has been configured to allow
resetting totalizers from the display, you can use the display to define or change the high setpoint
(Setpoint A). See Figure C-10.
5. Use the discrete input interface (see Section 6.8) to assign one or more actions to the event,
i.e., specify the action(s) that the transmitter will perform if the event occurs.
