Status codes
Introduction
The following status codes are defined for the IEC 60870-5-101 slave protocol. Some
typical reasons for some of the status codes are also given.
Link layer status codes
17600
IGTP_REMOTE_LINK_CONTINUOUSLY_BUSY. The Data Flow Control ( DFC)
bit of the messages from the master is set for more than 15 seconds.
17601
IGTP_TIMEOUT_WHILE_TRANSMITTING. The CTS signal or the end of
transmitted message is not received in correct time. The DE attribute controls
the CTS waiting time; the transmission time of message is automatically calcu-
lated.
17602
IGTP_TIMEOUT_WHILE_WAITING_RESPONSE. Timeout while waiting for an
acknowledgment to a message.
17604
IGTP_LINK_NOT_READY. The application level sends a command before the
communication between the master and the slave is established.
17605
IGTP_REMOTE_LINK_BUSY. Data sending fails since the Data Flow Control
bit (DFC) is set in remote station and there is already one data message waiting
to be reset. Not used in the unbalanced slave.
17606
IGTP_REMOTE_LINK_NOT_RESPONDING. The slave does not receive a reply
from the master.
17607
IGTP_LINE_STARTED. The station has been set in use by using the IU attribute.
17608
IGTP_LINE_STOPPED. The station has been set out of use by using the IU
attribute.
17609
IGTP_MESSAGE_RECEIVING_STOPPED. A watchdog mechanism in an
unbalanced slave station has detected that it is polled no more. The line is
automatically returned to OK, when polling is restarted.
17610
IGTP_RECEIVER_OUT_OF_BUFFERS. Internal software error.
17620
IGPC_ILLEGAL_ATTRIBUTE_VALUE. The value written to one of the line
attributes is incorrect.
