ERROR STATUS
(decimal)
Description
1 4 Error in transmission range pointers SD_i with respect to
the length or the data type
1 8 Partner CPU access error
1 10 Access to local application memory not possible (e.g.
access to deleted DB).
1 12 The call to the FB/SFB
contains an instance DB that does not belong to the
FB/SFB 15.
contains a global DB instead of an instance DB.
could not locate an instance DB (load a new instance DB
from the PG).
1 20 Not enough memory.
n Siemens S7-300 Communication
– In order to ensure data consistency, send area SD_1 may not be used again for
writing until the current send process has been completed. This is the case when
the state parameter DONE has the value "1".
n Siemens S7-400 Communication
– When a send operation is activated (rising edge at REQ) the data to be sent from
the send area SD_i are copied from the user program. After the block call, you
can write to these areas without corrupting the current send data.
8.2.13 FB 55 - IP_CONF - Progr. Communication Connections
8.2.13.1 Overview
To configure flexible communication connections, the FB 55 - IP_CONF allows the pro-
gram controlled transfer of data blocks with configuration data for a CP.
Please note that this block calls the FC or SFC 204 IP_CONF internally.
These must not be overwritten! The direct call of an internal block leads
to errors in the corresponding instance DB!
Configuration data for communication connections may be transferred to the CPU by the
FB 55 called in the user program. The configuration DB may be loaded into the CP at any
time.
