If the existing data block is too short, different procedures are used for the various SIMATIC
product series:
●
For S7-300
A new DB is generated. The old DB remains in memory because S7-300 has no delete
function for data blocks.
With CPU 300, you have to delete the old DBs with the programming device.
Note:
Without generating a new DB, you would need to delete this DB with the programming
device. If there is not enough memory on the CPU to be able to generate a new DB, you
need to delete the existing DB before restarting.
●
For S7-400
The existing DB is deleted, the memory is compressed and the DB is then generated with
the same number in the new length.
With the CPU 400, you may be able to compress the memory manually or reload the
CPU.
●
For S7-1500
The existing DB is deleted and generated in the new length with the same number.
With the CPU 1500, the memory is automatically compressed, as with the CPU 300.
If the ListGenerator FC can no longer generate a DB, an error message is written to the
diagnostic buffer of the CPU:
●
0xB107 "Error generating the object reference list"
–
DB[Info1]
DB[Info1] cannot be created.
–
Cause: [Info2].
In Info2, the return value of the SFC Create_DB function is output, refer to the
description there.
5.7.2.2
FC PartnerMonitor
Function
FC PartnerMonitor has the following functions:
●
It displays important status information about a SINAUT subscriber (see "PartnerStatus"
parameter).
●
The FC can also be used to trigger a general request of the subscriber, except to a
control center (e.g. ST7cc/ST7sc).
●
It can also be used to establish and terminate a permanent connection to the subscriber.
The FC can be called at any point in the cyclic user program (in OB1).
If you want to monitor and control more than one subscriber, include an appropriate number
of FC PartnerMonitor in the user program.
