Model 2400S Transmitters for PROFIBUS-DP
Optional Configuration
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 (Diagnostic block, Index 6) is used.
• If Event Type is In Range or Out of Range, both Setpoint A (Diagnostic block, Index 6)
and Setpoint B (Diagnostic block, Index 7) 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, if the event type is High or Low, and the transmitter is configured to allow resetting
totalizers from the display, you can use the display to define or change the high setpoint (Setpoint A).
See Section 7-3.
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 C-3.
Note: For consistency with other Micro Motion products, the Discrete Input panel is used here even
though the Model 2400S DP transmitter does not provide a discrete input.
• Using the display, see Figure C-15 and use the ACT submenu.
• Using a PROFIBUS host with the EDD, see Figure C-10.
• Using PROFIBUS bus parameters, use Index 83 in the Diagnostic block (see Table D-4) to
specify the event, and Index 82 to assign the action.
Table 8-5 Event types
Type Description
High (> A) Default. Discrete event will occur if the assigned variable is greater than the setpoint (A).
(1)
(1) An event does not occur if the assigned variable is equal to the setpoint.
Low (< A) Discrete event will occur if the assigned variable is less than the setpoint (A).
(1)
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).
(2)
(2) An event occurs if the assigned variable is equal to the setpoint.
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).
