Notes for Transducer Blocks, all releases:
1. Diagnostic Parameter. This parameter is only accessible if TEST_MODE bit 7 ‘Enable Diagnostic
Scan List’ is set.
2. DAC_VALUE can only be written if TEST_MODE bit 7 AND bit 0 ‘Write to DAC_Value’ are set.
3. Parameter may not be written if SIG_FLAGS bit 0 ‘BEGIN_SIG’ is set. (The Signature Analysis
program is running.)
4. 0x00 if the positioner is a standard model. Advanced Model if the positioner is an advanced type
(pressure sensors). This is determined from hardware settings at start-up
5. This enumeration shows ‘Uninitialized’ when value is 0.

8.9 Link Objects
Background
The function blocks configured to control a process are linked, or connected by objects within the
devices. These links allow the user to transfer process and event data from one block to another. These
links are defined through link objects.
