Value Description
80C2h Temporary lack of resources for the communication partner, e.g.:
n The communication partner is currently processing the maximum number of operations.
n The required resources (memory, etc.) are already occupied.
n Not enough memory (initiate compression).
80C3h Error when establishing a connection, e.g.:
n The local station is connected to the MPI sub-net.
n You have addressed the local station on the MPI sub-net.
n The communication partner cannot be contacted any longer.
n Temporary lack of resources for the communication partner.
14.1.53 SFC 69 - X_ABORT - Disconnect
The SFC 69 X_ABORT can be used to terminate a connection to a communication
partner that is located outside the local station, provided that the connection was estab-
lished by means one of SFCs 65, 67 or 68. The operation is started when input param-
eter REQ is set to 1. If the operation belonging to SFCs 65, 67 or 68 has already been
completed (BUSY = 0) then the connection related resources occupied by both partners
are enabled again when the call to the SFC 69 has been issued.
However, if the respective operation has not yet been completed (BUSY = 1), the call to
the respective SFC 65, 67 or 68 must be repeated after the connection has been termi-
nated with REQ = 0 and CONT = 0. The connection resources are only available again
when BUSY = 0. The SFC 69 can only be called on the side where SFC 65, 67 or 68 is
being executed.
Parameter Declaration Data type Memory block Description
REQ INPUT BOOL I, Q, M, D, L,
constant
Control parameter "request to activate", used to
initiate the operation.
DEST_ID INPUT WORD I, Q, M, D, L,
constant
Address parameter "destination ID". Contains the
MPI address of the communication partner.
RET_VAL OUTPUT INT I, Q, M, D, L The return value contains an error code if an error
is detected when the function is being processed.
BUSY OUTPUT BOOL I, Q, M, D, L BUSY = 1: connection termination not yet com-
pleted.
BUSY = 0: connection termination has been com-
pleted.
The connection termination initiated by means of the SFC 69 is still completed, even if the
CPU changes to STOP mode.
A transition to operating mode STOP of the CPU of the communication partner does not
affect the connection termination, the connection is terminated in spite of the change of
operating mode.
