Set Polling Control
n
as one of the following options:
The
n
is the value you selected in the Polling Slot field.
If there is another master, and if that master is primary, then set this field to
secondary. If the other master is secondary, then set this field to primary.
Option
Description
Poll as Primary
No other HART masters will be on the network.
Poll as Secondary
Other HART masters will be on the network.
3.
Set External Device Tag
n
to the HART tag of the device being polled.
The
n
is the value you selected in the Polling Slot field.
•
The device being polled (slave) cannot have special units set for density.
Otherwise, the master will reject the base density and report the following alarm:
A115: No External Input or Polled Data Alert
•
On the slave side, setup the HART Primary Variable for
Base Density
. The master
will reject anything other than
Base Density
for the HART Primary Variable and
trigger an A115 alarm.
•
The density units on the transmitter and the polled device can be different as
long as they can be classified as density units; for example, kg/m
3
and g/cm
3
.
The transmitter converts the polled units into compatible specified units.
For wiring and setup instructions for a polled device, refer to the
Micro Motion Gas
Density Meters (GDM) Installation manual
or the
Micro Motion Specific Gravity Meters
(SGM) Installation manual
.
