MBPSTAT Diagnostics
This troubleshooting section applies to Users that have access
to a utility from Modicon called MBPSTAT. This utility is shipped
with the SA-85 Modbus Plus Communications Card, and allows
easy access to Modbus Plus Network status and statistics.
The data that is available with the utility includes:
Active Node List: If there is doubt as to whether or not the
MBP node is seen on the network, this list will show all
active nodes
Global Data: The utility will read the Global Out Data being
transmitted from each node, allowing a user to see the
actual values coming out of any node
Node Statistics: This screen will show you the
communication status and error counters within each node.
This data is useful if unusual communication problems are
occurring
