7-31
Disable/Enable data block
Set:
Per user: to avoid overwriting an area by the RECEIVE
block res. data transition of an area by the SEND block
(only for the first data block).
Delete:
Per user: to release the according data area.
Analyze:
Per handling blocks SEND and RECEIVE: if Bit 7 is set,
there is no data transfer anymore, but the blocks
announce an error to the CP.
Those bits announce the error messages of the order. The error messages
are only valid if the bit „Order ready with error“ in the status bit is set
simultaneously.
The following error messages may occur:
0
no error
If the bit "Order ready with error" is set, the CP had to reinitialize
the connection, e.g. after a reboot or RESET.
1
wrong Q/ZTYP at HTB
The order has been parameterized with the wrong type label.
2
AG area not found
The order impulse had a wrong parameterized DB-No.
3
AG area too small
Q/ZANF and Q/ZLAE overwrite the range boundaries. Handling with
data blocks the range boundary is defined by the block size. With flags,
timers, counters etc. the range size depends on the AG.
4
QVZ-Error in the AG
This error message means, that you chose a source res. destination
parameter of the AG area, where there is either no block plugged in or
the memory has a defect. The QVZ error message can only occur with
the type Q/ZTYP AS, PB, QB or memory defects.
5
Error at indicator word
The parameterized indicator word can not be handled. This error occurs,
if ANZW declared a data word res. double word, that is not (any more) in
the specified data block, i.e. DB is too small or doesn’t exist.
6
no valid ORG-Format
The data destination res. source isn’t declared, neither at the handling
block (Q/TYP="NN") nor at the coupler block.
7
Reserved
8
no available transfer connections
The capacity for transfer connections is at limit. Delete unnecessary
connections.
9
Remote error
There was an error at the communication partner during a
READ/WRITE-order.
A
Connection error
Bit 7
Error management
Byte 1,
Bit 0 to Bit 3
