Error information
ERROR STATUS Description
0 0000h New data were accepted. The current length of the received data is shown in
RCVD_LEN.
0 7000h First call with REQ = 0, receiving not initiated
0 7001h Block is ready to receive.
0 7002h Follow-on call, job being processed
Note: during this processing the operating system writes the operating system data to
the DATA receive buffer. For this reason, an error could result in inconsistent data
being in the receive buffer.
1 8085h LEN parameter is greater than the largest permitted value, or you changed the value
of LEN from the one that existed during the first call
1 8086h The ID parameter is not in the permitted address range
1 8088h
n Target buffer (DATA) is too small.
n The value in LEN is greater than the receiver area specified by DATA.
1 8089h Parameter ADDR does not point to a data block.
1 80A1h Communications error:
n FB 65 TCON was not yet called for the specified ID
n The specified connection between the user program and the communication level
of the operating system is currently being terminated. Receiving over this connec-
tion is not possible.
n The interface is being reinitialized (receiving new parameters).
1 80B3h The parameter for the connection type (connection_type parameter in the connection
description) is not set to UDP.
Please use the FB 64 TRCV.
1 80B7h Length error: The parameter ADDR is the length specification < 8byte.
1 80C4h Temporary communications error:
n The connection is currently being configured (or TCON is still running).
