Each POINT I/O connection established with the 1734-AENT adapter
consumes a portion of the microprocessor's bandwidth. The amount of
bandwidth used by a connection depends on a number of variables, including
the requested packet interval (RPI), the number of POINT I/O modules
involved in the connection, and the rate of change of the I/O.
The 1734-AENT adapter continuously monitors this bandwidth and rejects
requests for new connections when there is insufficient bandwidth available to
support the new connection.
The condition where the 1734-AENT adapter cannot support the connection
due to a limit of the microprocessor's bandwidth is shown in the following
dialog.
If you encounter this condition, the only action you can take is to alter the
existing connections to reduce the amount of microprocessor bandwidth
consumed. The most likely fixes for this condition include the following.
• Increase the RPI.
• Decrease the number of connections.
