7.3 Transmitter Channel Configuration
Channel Status
Using the WDM interface, each transmitter channel can be configured as per available options.
More details about the WDM interface can be found in
References.
After provisioning, or after transmitter is reset to default settings, the channels are not enabled
(Unassigned) and the LCD indicates: “NoChEn”.
Once channels are configured, they will be shown on the LCD as “CHAN #” followed by its
status/PV value (for example “OOS”, or PV value) followed by the measurement units.
Channel Configuration
To configure a channel in WDM interface:
•
In Transmitter menu -> Channel Configuration: Select channel and channel type
and then Save setting. The LCD display will indicate the activated channel.
o
to disable/remove a channel, set it to “Unassigned”
•
In Channel menu -> Select Sensor type (if applicable) and then Save setting
•
In Channel menu -> Select Scale and units (if applicable) and then Save setting
•
In Channel menu -> Select Mode (i.e. AUTO). The LCD display will indicate
the PV value for the activated measurement.
•
In Transmitter menu -> Input Publication select Publication rate (i.e. 30 seconds)
and Attribute to be published for each activated channel (i.e. PV) and then Save
setting. The WDM will display the activated channel and the PV received at the
selected published rate interval.
ATTENTION
Minimum Publication rate value selectable from WDM interface is ½ second. This can be
achieved only for a single Channel measurement. If more than one cannel is configured and
enabled, then Input publication rate must be greater than 1 second.
The Process Variable (PV) is available for monitoring and alarm purposes. The cold junction
temperature is also available for monitoring. Slower update rates extend battery life.
