User Address Comments
MajorVersion Software version per E-Bus Mechanism document.
FileTxTimer Used when the file is opened for SENDING. Explicit address of the RECEIVER (either subnet/node or group
address), retry count, a transaction time used for the request/response message at the end of every window
and an indication whether authenticated and/or priority messaging should be read.
FileTypeGrp Used when the file is opened for SENDING. Explicit address of the RECEIVER (either subnet/node or group
address), retry count, a transaction time used for the request/response message at the end of every window
and an indication whether authenticated and/or priority messaging should be read.
InUseNumber InUseNumber is used by a management node to indicate to all other management nodes that it is
logged on
to
the Excel 10 node and that they should not try to interact with any of the Excel 10 network variables or
configuration parameters. Before the management node reads or writes any network variables, the
management node checks InUseNumber for a zero value meaning no other management nodes are already
logged on
and that a management node can log on to the node. Then the management node writes a number,
1 through 65534, to InUseNumber and periodically writes the same value to indicate that the management
node is still logged on. If there are no writes made to InUseNumber for approximately 60 seconds, then the
Excel 10 resets InUseNumber to zero to automatically log off the management node. Before interacting with
any network variables, the management node verifies that the InUseNumber has not changed. The
management node
logs off
by writing 0 to InUseNumber.
During power up, an application restart, or return to on-line from off-line, the Excel 10 sets InUseNumber to
65535 to indicate to the management node that it is now on-line.
FileStatDomainLen If the last operation was an FR_OPEN_TO_SEND, FR_OPEN_TO_RECEIVE, FR_OPEN_TO_SEND_RA, or
FR_OPEN_TO_RECEIVE_RA, these fields contain the full address of the initiator. If there are multiple
initiators then there may be several operations attempted concurrently on the same set of file transfer network
variables. Each initiator is responsible for checking its own address against the value returned in the file status
to ensure that is was granted requested access. An initiator must not close a file unless it was granted access.
FileStatInfo A sixteen character string with information about the file.
FileStatNode If the last operation was an FR_OPEN_TO_SEND, FR_OPEN_TO_RECEIVE, FR_OPEN_TO_SEND_RA, or
FR_OPEN_TO_RECEIVE_RA, these fields contain the full address of the initiator. If there are multiple
initiators then there may be several operations attempted concurrently on the same set of file transfer network
variables. Each initiator is responsible for checking its own address against the value returned in the file status
to ensure that is was granted requested access. An initiator must not close a file unless it was granted access.
FileStatSize The number of bytes in the last selected file.
FileStatSubnet If the last operation was an FR_OPEN_TO_SEND, FR_OPEN_TO_RECEIVE, FR_OPEN_TO_SEND_RA, or
FR_OPEN_TO_RECEIVE_RA, these fields contain the full address of the initiator. If there are multiple
initiators then there may be several operations attempted concurrently on the same set of file transfer network
variables. Each initiator is responsible for checking its own address against the value returned in the file status
to ensure that is was granted requested access. An initiator must not close a file unless it was granted access.
FileStatus Internal Use Only.
InvalidId If EVObjectldin is not a valid object, InvalidId is set to True; otherwise it is set to False.
InvalidRequest If EVObjectRqst is not a valid request for the object addressed, InvalidRequest is set to True; otherwise it is set
to False.
