8 E O/S The 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, 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 E O/S The 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, 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.
(1) PRESSURE can be written in O/S mode if the PRESSURE_SOURCE is set to “Constant”
(2) TEMPERATURE can be written in O/S mode if the TEMPERATURE_SOURCE is set to “Constant”
