Designation
Cause
Possible solution
7000 ERR_IOL_CALL_
CONFLICT
Error when applying the
configuration. Extended error
information is available from the
low byte (see the following table).
An attempt is made to write a read-
only record.
Check IOL_CALL
7001 ERR_WRONG_IOL_
CALL
An incorrect IOL_CALL was
transmitted. Wrong value for
Control byte or FI index.
Check IOL_CALL
7002 ERR_PORT_
BLOCKED
Error during ISDU communication.
Service handler busy. Incorrect
value in the IOL-CALL.
Repeat ISDU request at a
later time. Check
IOL_CALL
8001 ERR_WRONG_
INDEX
IOL_Index is equal to or greater
than the value 32768 (0x8000).
Request to the master port does not
contain indexes 0x100, 0x200,
0x300, 0x400, 0x500.
Check IOL_Index.
8002 ERR_WRONG_
PORT_ADDRESS
Invalid port number
Check IOL_CALL.
Valid port numbers are
0..4.
If the error "R_CM_PEND_CHNG" (0x11nn) is returned, extended error
information can be taken from the low byte of the "IOL-M_error_code":

Designation
Cause
Possible solution
00 MG_ERR_CM_PE
ND_CHNG
Password incorrect
Check password.
01 RET_ERR_SIO_BY
TE_OFFSET
Offset of the SIO byte is incorrect.
Check SIO byte offset. It
must be >= Mailbox
1.
02 RET_ERR_TOTAL
_SEGM_LEN
Total length of the segmentation
surpasses the total length of the
internal bus telegram.
Check segmentation.
03 RET_ERR_PORT1_
UPSTREAM_LEN_
AND_OFFSET
Length and offset of the upstream
segmentation from port 1 is faulty.
Segmentation overlaps other data
segments. Segmentation overlaps
internal bus data width.
Check segmentation.
04 RET_ERR_PORT1_
DOWNSTREAM_L
EN_AND_OFFSET
Length and offset of the downstream
segmentation from port 1 is faulty.
Segmentation overlaps other data
segments. Segmentation overlaps
internal bus data width.
Check segmentation.
05 RET_ERR_PORT1_
CYCL_MBX_LEN
Length of the fragmented data segment
for port 1 is faulty.
Check the length of the
segment. Length must be
> 0 bytes. Both upstream
and downstream lengths
cannot be 1 byte.
