DOIO functionality is not supported to the embedded PROFIBUS
interface at this time. The DOIO function block does not return an
error if it is executed using the embedded PROFIBUS as a target.
Get Device Status COMMREQ The Get Device Status COMMREQ is used to get detailed status
information about a particular device on the PROFIBUS network. In
order to get the most up to date data, a change was made after the
initial release to make this an active network command. In the first
release, this information was returned to the user application based
on buffered data. After the initial release, this data is actively
requested from the network. If the user application uses the Get
Device Status COMMREQ often, there is a potential to impact
network performance.
Total Configuration Size The various memory resources within the PLC CPU constrain the
number and type of slave devices and the amount of data they can
exchange with the master. The amount of memory available for the
PROFIBUS configuration is affected by the number and type of
slave modules in the network configuration.
The CPU366 provides up to 8K bytes (physical memory) of resource
data. This is defined by each slave module’s GSD file, and can vary
depending on the types of modules.
PROFIBUS Data Sizes The amount of data that can be configured on the CPU 366
PROFIBUS network provides up to 2048 bytes input and 2048
bytes output.CPU366 was switched from
STOP to RUN mode, word
offset 28 of the PID parameter
block would be cleared.
Two parameters ‘Upper Range for SP,PV’ and
‘PREV_FILT_DERIV_TERM’ inadvertently overlapped at word
offset 28 of the PID parameter block causing it to be cleared when
switched from STOP to RUN.
The problem has been fixed by removing the overlap of parameters.
The parameter PREV_FILT_DERIV_TERM is now addressed to
word offset 30.
