If there is no error, STATUS_SEND = 0000h or 8181h. With an error here the corre-
sponding error code may be found. As long as ERROR_SEND is set, the value of
STATUS_SEND is available. Following status messages are possible:
STATUS Description
0000h There is no error.
0202h IO_SIZE is not valid (IO_SIZE = 0 or IO_SIZE > 60).
0301h DB is not valid.
070Ah Transfer failed, there is no response of the partner or the job was
negative acknowledged.
0517h LEN is not valid (LEN = 0 or LEN > 1024).
8090h HW_ID is unknown.
80A0h When accessing the periphery, an access error was detected.
80A1h
8181h Job is running (status and no error message).
8323h Send DB available, but too short.

Length Receive:
n Length of the received telegram in byte.
n 1 ≤ LEN_RCV ≤ 1024
New data ready:
n New received data are ready in receive DB. Signal stays for one cycle.
n Received data without error: Parameter STATUS_RCV = 0000h.
ERROR_RCV is set at order ready with error. Here STATUS_RCV contains the corre-
sponding error message.
