Configuring a temperature source

External temperature data is reported through an analog output (AO) function block. The transmitter
has two AO blocks, each of which can be assigned to a compensation variable channel.
To configure an AO function block for temperature compensation:
• With the EDD, refer to the flowchart in Figure 2-9.
• With bus parameters, refer to the flowchart in Figure 2-10.
• With the display, refer to the flowcharts in Figure B-15.

General
Set IN Channel to
Temperature
Block: Transducer Block 1 (Slots 11)
Index 121 (AO Compensation), value = 1
Block: Analog Output Block (Slots 9 and 10)
Index 37 (IN channel), value = 0x0b1D
Index 38 (OUT channel), value = 0x0b6F
Note: When setting the IN
channel to Temperature via the
EDD, the OUT channel will be
automatically set to
Temperature as well. Setting
the IN channel via bus
parameters does not
automatically change the OUT
channel. You must manually set
the OUT channel to
Temperature or the block will
go into Out of Service mode.
