Emerson Process Management 2400S manual 5 Event types, 6 Event actions

Optional Configuration

3.Assign a process variable to the event (Attribute 10).

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 Setpoint A is used (Attribute 8)

•If Event Type is In Range or Out of Range, both Setpoint A and Setpoint B (Attributes 9 and 10) are required.

5.Assign the event to an action or actions, if desired. Possible actions are listed in Table 8-6.To do this:

•Using ProLink II, open the Discrete Input panel in the Configuration window, identify the action to be performed, then specify the event using the dropdown list. See Figure B-3.

Note: For consistency with other Micro Motion products, the Discrete Input panel is used here even though the Model 2400S DN transmitter does not provide a discrete input.

•Using the display, see Figure B-6and use the ACT submenu.

•Using a DeviceNet tool, refer to Table C-7,use Attribute 84 to specify the action to be performed, and set Attribute 85 to specify which event will initiate the action.

Table 8-5Event types

	DeviceNet
Type	code	Description
High (> A)	0	Default. Discrete event will occur if the assigned variable is greater than the
		setpoint (A).(1)
Low (< A)	1	Discrete event will occur if the assigned variable is less than the setpoint (A).(1)
In Range	2	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).(2)
Out of Range	3	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).(2)

(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.
