A transition to operating mode STOP of the CPU of the communication partner does not
affect the data transfer, since it is also possible to read data in operating mode STOP.
The "real error information" that is contained in the table "specific error information" may
be classified as follows:
Value Description
809xh Error on the CPU where the SFC is being executed
80Axh Permanent communication error
80Bxh Error on the communication partner
80Cxh Temporary error
Specific error information:
Value Description
0000h Processing completed without errors.
00xyh RET_VAL contains the length of the received data block.
7000h Call issued with REQ = 0 (call without processing),
BUSY is set to 0, no data transfer is active.
7001h First call with REQ = 1: Data transfer started;
BUSY has the value 1.
7002h Intermediate call (REQ irrelevant): data transfer active; BUSY is set to 1.
8090h The specified target address of the communication partners is not valid, e.g.:
n bad IOID
n bad base address exists
n bad MPI-address (> 126)
8092h Error in SD or RD, e.g.:
n illegal length for RD
n the length or the data type of RD does not correspond with the received data.
n RD = NIL is not permitted.
8095h The block is already being processed on a priority class that has a lower priority.
80A0h Error in received acknowledgement.
80A1h Communication failures: SFC-call after an existing connection has been terminated.
80B0h Object cannot be found, e.g. DB was not loaded.
80B1h ANY-pointer error. The length of the data block that must be transferred is wrong.
80B2h HW-error: module does not exist
n The slot that was configured is empty.
n Actual module type does not match the required module type.
n Decentralized periphery not available.
n The respective SDB does not contain an entry for the module.
80B3h Data may only be read or written, e.g. write protected DB.
