440 01b8 Max Services Outstanding Called parameter proposed to the remote node is too small for the
desired communication.
Decimal: Hex: Description:
441 01b9 The remote node determined that a necessary parameter CBB is not present in the proposed list.
442 01ba The Proposed Data Structure Nesting Level is too small for the desired communication to the
remote node.
443 01bb The remote node determined that a necessary service CBB is missing from the proposed list.
446 01be General problem with conclude service at remote node.
447 01bf The remote node cannot conclude because responses are not generated for all confirmed service
requests, or because upload state machine exists.
456 01c8 General problem with cancel request at remote node.
457 01c9 The attempted cancel service could not be completed at remote node due to invoke ID mismatch.
458 01ca The cancel service cannot be performed at remote node according to service requirements.
486 01e6 The variable at the remote node has an undefined reference attribute. This is a permanent error for
access to this variable.
487 01e7 Cannot access the variable at the remote node due to a hardware fault.
488 01e8 The requested variable is temporarily unavailable at the remote node.
489 01e9 The remote MMS client has insufficient privilege to request this operation.
490 01ea The variable does not exist at the remote node.
491 01eb The remote variable is invalid because the format of its address is incorrect or the address is out of
range.
492 01ec An inappropriate or unsupported type is specified for a variable at the remote node.
493 01ed The remote node determined that the type specified is inconsistent with the service requested or
with the referenced variable.
494 01ee The remote node determined that the object is specified with inconsistent attributes.
495 01ef The remote variable is not defined to allow the requested access.
496 01f0 The requested variable does not exist at the remote node.
506 01fa The local node determined that the communication protocol is invalid. This indicates an
inter-operability problem -- please contact Allen-Bradley.
507 01fb The remote node determined that the communication protocol is invalid. This indicates an
inter-operability problem -- please contact Allen-Bradley.
