STB AVO 0200 Data and Status for the Process Image
Representing
the Analog
Output Data
The NIM keeps a record of output data in one block of registers in the process
image. Information in the output data block is written to the NIM by the fieldbus
master and is used to update the output modules. This information can be monitored
by the fieldbus master. If you are not using a basic NIM, the information may also be
monitored by an HMI panel connected to the NIM’s CFG port.
The output data process image is a reserved block of 4096 16-bit registers (in the
range 40001 through 44096) that represents the data sent by the fieldbus master.
An STB AVO 0200 is represented by two contiguous registers in the output data
block. The specific registers used by an STB AVO 0200 module are based on its
logical address on the island bus.
Output
Data Registers
Each STB AVO 0200 output data register represents the output data in the IEC data
format. The data has 15-bit + sign resolution.
Note: The data format illustrated below is common across the island bus,
regardless of the fieldbus on which the island is operating. The data is also
transferred to and from the master in a fieldbus-specific format. For fieldbus-
specific descriptions, refer to one of the Advantys STB Network Interface Module
Application Guides. Separate guides are available for each supported fieldbus.
Note: Errors and warnings are based on count values, not current values. The
current values in the table below are ideal values.
