Detailed definition of the status data area can be found in Status Data Definition
(page 61). These areas include the following: Global In Update Status, Master
Command Status, Misc Module Status and Global In Update Counters.
Definition of the configuration data areas can be found in Configuration Data
Definition. These data areas include the following: Module Configuration Block,
Global In File Map, Device Definition, Master Command List.
The Global Out Image is a data area of 40 words. Only the first 32 words are
filled with data. This data is transferred from the processor to the module on each
write block command and placed on the Modbus Plus network. This data area is
used for high-speed data that must be passed to other nodes on the network at a
high frequency.
The Global In Image is a data area of 40 words. Only the first 32 words are filled
with data. This data is transferred from the module to the processor on each
block read command. Data in the block is determined by the Global In File Map
data set. This data area is used for high-speed data that must be passed to the
processor at the highest frequency.
The Command Event Data area controls master commands under processor
control. This data area is updated on each write block transfer from the processor
to the module. Each bit in the data area corresponds to a command in the master
command list. When the bit is set high, the command will be issued. When the bit
is clear, the command will not execute. Event command control bits apply only to
commands that have a value of two for their Enable parameter in the master
command list
5.7.2 Status Data Definition
This section contains a description of the members present in the MBPStat
object. This data is transferred from the module to the processor approximately
every second.
