Configuring Latching Period

The Rosemount 702 for plunger arrival includes the ability to latch plunger arrival events for a configurable duration. See figures below for an example of the latching period.

Short Latch Time EventsFigure 2-2:

A: Measured

B: Reported

Short events (less than latch hold time) of the measured value will be latched to the

Reference Manual 29

reported value for the duration of latch hold time.

Configuration

The start of latch hold timer will begin when the measure signal first transitions to active state.

Latch Hold TimerFigure 2-3:

A: Measured

B: Reported

2.4.1

Note

The default for the plunger arrival option will be to latch high. This is what is required to function with the ETC cyclops arrival sensor.

For full latching details refer to Section 5.2 of this manual.

The duration should be configured to hold the plunger arrival event long enough for the rest of the system to react. Considerations such as wireless update rate, Modbus/OPC scan rates, etc. should be taken into account while setting the latch duration. To avoid the potential for missing arrival events, the latch duration should be greater than or at least equal to the configured wireless update rate. The default update rate for the plunger arrival option is 16 seconds and the default latch duration is 60 seconds.

To configure the latch period refer back to Section 2.2.5 and follow the steps to reach setup channel 1.

System verification

After installation of the 702DX52 for plunger arrival one must verify functionality.

• Verify the sensor: To do so, pass a ferrous object (ex. Wrench) past the cyclops

sensor to simulate an arrival. Verify via the LCD screen and/or field communicator that channel 1 indicates a state change. If a state change is seen, sensor wiring is correct; if nothing is seen, please go back through the installation steps and confirm that everything has been done accordingly.

• Verify System integration: It is important to verify the latch time is configured

correctly. The default latch period is set to one minute. Verify the host system can detect the arrival event by moving a ferrous metal object (ex. Wrench) past the arrival sensor. The signal should be passed from the device, through the Wireless Gateway and detected at the final host application (ex. PLC, Modbus/OPC , etc.). If nothing is seen, confirm the latch time is appropriate considering the full system scan cycle.

Reference Manual 49

Operation

5.2 Defining channel descriptions

The 702 provides four device variables:

• Plunger arrival state (channel 1) – By default when a plunger event is detected, this

value state will indicate “True” and will remain true for the duration of the configured latching time. A reported value of “False” indicates that a plunger event has not been detected. Other reported values can also be configured, refer to

AMS Wireless Bench Config.

• Plunger arrival counts (channel 1) – Reports the number of plunger state transitions

that have occurred since the last reset.

• Power savings state (channel 2) – By default power savings state is set to “False.”

This indicates that power is being provided from the 702 to the plunger arrival sensor. The setpoint for this variable can be set to “True” which would remove power from the sensor if desired. WARNING - This is an advanced setting and not recommended for most applications. When power is removed, plunger arrival states WILL NOT be detected. If more information on this feature is desired contact your local sales representative.

• Power saving counts (channel 2) – Reports the number of times power savings state

has been enabled. (This would normally be reported at zero for most applications).

• Electronics temperature – This indicates the internal operating temperature of the

device. For normal operation, this should be within the limits specified in

Section 9.3.3. The value can be configured to report either Celsius or Fahrenheit, see AMS Wireless Bench Config.

• Supply Voltage – This indicates the effective voltage delivered by the power module.

When the voltage falls below 6V, the power module should be replaced soon. When the voltage falls below 5.2V the 702 will no longer provide plunger state measurements and the power module must be replaced to restore proper operation.

Latching feature

The Rosemount 702 has a latching feature that, when enabled, allows detection of momentary state changes to be held for a configurable latch period. The latching feature can be configured to detect either high or low state changes. By default, the Plunger state (channel 1) is enabled to latch high state changes for a period of one minute.

The following are some examples to demonstrate how the latching time works.

Note

Hold time is set to four seconds for illustration in the following examples.

Short events (less than latch hold time) of the measured value will be latched to the reported value for the duration of latch hold time.

Operation

Latch Time Short EventsFigure 5-1:

A. Measured B. Reported
