Behavior - Allen-Bradley 1444-TSCX02-02RB User Manual

Example, where identifier lower 16 bits are 0x 0024
• 00 indicates that measurement unit is Volt
• Bits 2 & 5 are set to indicate path 1 is in use and synchronous sampling is
enabled (so data is based on synchronous sampling)

Behavior

Through the Object-specific services 0x4B and 0x4C, the Advanced CM Data
Object gives access to dynamically configurable analysis data (variable FFT
lines, and so on). The service 0x4B configures/requests the desired processing
be implemented, while the service 0x4C is used to request the resulting data.
One request can include multiple channels and data types to avoid the
complication of varying record sizes the resulting data can be requested on one
channel and data type per session basis.
See the Data Manager Object for access to historical data (Trend and Alarm),
to the Normal CM Object for access to a 'Live' version of that data. Also see the
Transient Data Manager Object for access to stored transient event data.
