O/S
8 Channel through which the absolute pressure is
communicated. When AO.OUT value is used, FAULT_STATE
is used if status goes bad. When CAS_IN shadow is used,
E O/S bad status/value will be propagated to the mass flow block.
If a value of "Constant" is specified, the PRESSURE
parameter becomes writable in O/S and the constant value
is used in the calculation.

9 Channel through which the process temperature is
communicated. When AO.OUT value is used, FAULT_STATE
is used if status goes bad. When CAS_IN shadow is used,
E O/S bad status/value will be propagated to the mass flow block.
If a value of "Constant" is specified, the TEMPERATURE
parameter becomes writable in O/S and the constant value
is used in the calculation.
