5 I/O Assembly Object
Class Code 04
h
= 04
d
A collection of assembly objects allows the sending of attributes from different
application objects in one message (i.e. Polling I/O).
The S-Analog Sensor object definition specifies a behavior that modifies the Data
Type of certain attributes based upon the first valid I/O connection established to
an Assembly Object instance. In order to maintain consistency, this device type will
only allow connections to either INT or REAL based Assembly instances. Once a
valid connection is established, attempts to configure connections, or otherwise
access data, to a different type of Assembly instance will return a RESOURCE
UNAVAILABLE error.
The I/O Assembly DATA attribute has the format shown below:
Instance Type Byte Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
1 Input 0 - 1 INT Pressure Value
2 Input 0 Exception Status
