Recover From an Overloaded Adapter
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.
