Parameter Declaration Data type Memory area Description
NDR OUTPUT BOOL I, Q, M, D, L NDR status parameter:
n NDR = 0: Job not yet started or still running.
n NDR = 1: Job successfully completed
ERROR OUTPUT BOOL I, Q, M, D, L ERROR status parameter:
n ERROR = 1: Error occurred during pro-
cessing. STATUS provides detailed informa-
tion on the type of error
BUSY OUTPUT BOOL I, Q, M, D, L
n BUSY = 1: Job is not yet completed. A new
job cannot be triggered.
n BUSY = 0: Job is completed.
STATUS OUTPUT WORD M, D STATUS parameter: Status information
RCVD_LEN OUTPUT INT I, Q, M, D, L Amount of data actually received, in bytes
DATA IN_OUT ANY I, Q, M, D Receiving area (address and length)The address
refers to:
n The process image input
n The process image output
n A bit memory
n A data block
Allowed referenced data types: BOOL, BYTE,

Status 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. Receiving job has been activated.
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
value LEN is greater than the predetermined by DATA. Troubleshooting if the con-
nection type = 12h:
Increase the destination buffer DATA.
