Code:
String:
Explanation and Possible Causes/Solutions:
16#0301 Connection Request
Error: Out of buffer
memory.
The controller is attempting to set up a connection with the module and
has received an error – a module in the path is out of memory.
The controller may be attempting to connect to a tag in a producing
controller that is not marked as being produced.
The controller may be attempting to connect to a tag in a producing
controller. That tag may not be configured to allow enough consumers.§
Reduce the size or number of connections through this module.
One of the network modules between the module and the controller may
be out of memory. Check network configuration of the system.
The module may be out of memory. Check system configuration and
capabilities of module.
16#0302 Connection Request
Error: Out of
communication
bandwidth.
The controller is attempting to set up a connection with the module and
has received an error – a module in the path has exceeded its
communication bandwidth capacity. Increase the Requested Packet
Interval (RPI).
Distribute the load on another bridge module.
16#0303 Connection Request
Error: No bridge
available.
The controller is attempting to set up a connection with the module and
has received an error – a module in the path has exceeded its
communication bandwidth capacity. Distribute the load on another
bridge module.
16#0311 Connection Request
Error: Invalid port.
The controller is attempting to set up a connection with the module and
has received an error.
16#0312 Connection Request
Error: Invalid link
address.
The controller is attempting to set up a connection with the module and
has received an error – an invalid link address has been specified. A link
address can be a slot number, a network address, or the Remote I/O
Rack number and starting group.
Ensure that the chosen slot number for this module is not greater than
the size of the rack.
16#0315 Connection Request
Error: Invalid segment
type.
The controller is attempting to set up a connection with the module and
has received an error – the connection request is invalid.
16#0317 Connection Request
Error: Connection not
scheduled.
The controller is attempting to set up a connection with the module and
has received an error.
16#0319 Connection Request
Error: No secondary
resources available in
redundant chassis.
The controller is attempting to set up a connection with the module and
has received an error – the redundant module does not have the
necessary resources to support the connection.
Reduce the size or number of connections through this module or add
another Controller.
16#031d Connection Request
Error: Tag not
published.
The controller is attempting to connect to a tag in a producing controller
and has received an error.
The controller may be attempting to connect to a tag in a producing
controller and that tag is not marked as ‘published.
16#031e Connection Request
Error: Cannot
consume tag.
The controller is attempting to connect to a tag in a producing controller
and has received an error.
The controller is attempting to connect to a tag in a producing controller
and that tag has already been used by too many consumers. Increase
the maximum number of consumers on the tag.
