To configure flow direction:
• Using ProLink II, see Figure B-2.
• Using a DeviceNet tool, see Table C-1.
Note: This functionality is not available via the display menus.
8.6 Configuring events
An event occurs if the real-time value of a user-specified process variable varies above or below a
user-specified value, or inside or outside a user-specified range. You can configure up to five events.
You may optionally specify one or more actions that will occur if the event occurs. For example, if
Event 1 occurs, you may specify that the transmitter will stop all totalizers and inventories and reset
the mass totalizer.
8.6.1 Defining events
To define an event:
• Using ProLink II, see Figure B-3.
• Using a DeviceNet tool, event specifications reside in the Diagnostics Object (0x66),
Instance 1. See Table C-7.
The following general steps are required:
1. Select the event to define (Attribute 6).
2. Specify the event type (Attribute 7). Event Type options are defined in Table 8-5.
Table 8-4 Effect of flow direction on totalizers and flow values
Flow direction value
Forward flow (1)
(1) Process fluid flowing in same direction as flow direction arrow on sensor.
Flow totals Flow values
Forward only Increase Positive
Reverse only No change Positive
Bidirectional Increase Positive
Absolute value Increase Positive (2)
(2) Refer to the digital communications status bits for an indication of whether flow is positive or negative.
Negate/Forward only No change Negative
Negate/Bidirectional Decrease Negative
Flow direction value
Reverse flow (3)
(3) Process fluid flowing in opposite direction from flow direction arrow on sensor.
