8.5 - I/O Assembly Instances
The control instance indicates the significance of the control
setpoint:
1 = pressure control
2 = position control.
Note: The process variable will be based on the full scale
range of the active sensor except for instance 96 hex
and instance 98 hex, where it is based on the full scale
range of each individual sensor. The active sensor can
be determined from attribute 5F hex, Active instance
number, of the S-Analog Sensor Object, class instance 0.
Note: After establishing an I/O connection, data types of appli-
cation objects related to attributes included in the I/O assem-
blies will self-adjust to give consistency in data type between
pressure related and position related attributes. This applies
to attributes of the S-Analog Sensor Object, the S-Analog
Actuator Object and the
S-Single Stage Controller Object
Note: Assembly instances 97 hex and 98 hex are
described in detail in the Master/Slave Object section.
