Tasking


Data cannot be collected from a transmitter until a Task has been programmed. To create a new Task, click the New Task Button from Detail View, and the Transmitter Task page will appear.


Figure 1 - Task Setup



Description
Up to XX (TBC) Characters available to describe transmitter, e.g. transmitter Location
Data Logging Rate
Selection of Log Rate - available log rates: 1, 2, 3 5, 10, 15, 20, 30 minutes or 1 Hour
Temperature Scale
Choose °C or °F as required
Alarm Type
Un-tick the box for normal High and Low Alarm Threshold or Tick the box to use Alarm Zones
Wait for Manual Start
Tick the box to instruct the transmitter to wait for manual start command
Use Lethality/MKT
See Mean Kinetic Temperature and Lethality for more detail
Channel Name
Text box to identify each channel. (Up to XX (TBC) characters available)
Enable Ch
Enable or Disable individual channels
Enable Alarm
Enable Alarm Limits for individual channels
Alarm Delay
Set alarm time delay, e.g. for defrost cycle
Low Alarm
Value below which would trigger a Low Alarm event
High Alarm
Value above which would trigger a High Alarm event
Continuously open Alarm Trigger
Value in minutes that would trigger Door Continuously Open Alarm event
Average Alarm Period
Period over which Door Switch Alarms are averaged, e.g. 60 minutes (1 Hour)
Average Alarm Period Average period that cumulative Door open events would trigger an Average Door Open event



Task Validation

Task Validation is continuous while you are editing the Task. Mistakes or errors will be highlighted, and if ignored then at the point of program task a dialogue will appear warning of the errors. You will not be allowed to proceed until the errors are corrected.

Transmitter Task - Tasking

Click on to send the task to the Transmitter. The List View Home Page will indicate that the transmitter is Tasking. It can take several minutes for the Task to be sent to the transmitter because the Gateway must first wait for the transmitter to contact it.

Information Icon
A new Task command will overrule all other commands, so it is advisable only to re-task a transmitter that is not in the process of ADR (Automatic Data Recovery) as data not already received will be lost

Transmitter Task - RF515

The Task page for RF515 deserves special mention because it is very different from other transmitters, in that this page caters for both regular task setup and also configuration of scale mapping between analog units and engineering units of the sensor.

Note - New Picture Required!

Sensor Type
Select the option to match the sensor output
0V to 1V
0V to 10V
4ma to 20mA

Units
Engineering units for sensor. (Up to 8 characters available)
Decimal Places
The number of decimal places required for engineering units, (0 to 5)
Display xxxxx as yyyyy
These two sets of numbers define the scale mapping between measured units (V or mA) and sensor units. The example for Ext 1 shows 4 to 20mA mapping 0-100% RH
Lo Alarm & Hi Alarm
Alarm limits are entered using engineering units for the sensor


The allowable range of values for yyyyy in the display xxxxx as yyyyy field and also in Lo Alarm & Hi Alarm depends on the number of decimal places selected. See table below...

Decimal Places
Range
0
+/-32000
1
+/-3200.0
2
+/-320.00
3
+/-32.000
4
+/-3.2000
5
+/-0.32000
