OCX 8800
7-13
Input Failure
Set whenever there is a communication error between the Fieldbus card
and the OCX.
Simulation Active
Set whenever the Fieldbus Simulate Switch is set to ON at the Fieldbus
card or software simulate option enabled.
Other Error
Set whenever XD_ERROR is non-zero.
TRANSDUCER BLOCK
The Transducer Block was designed to provide the information necessary to
interface OCX 8800 to the Fieldbus.
