62 Wonderware Siemens SIMATIC NET S7 I/O Server

• Write complete (OK) - item: <item name> on: <topic name>

The write operation was completed successfully on the protocol. The PLC has

confirmed the reception of data.

• TRACE: <function for receiving data>: can't find message -> discarding it

(cpd=<CP-handle>,cref=<Conn-handle>,orderid=<orderid>

There’s no database for the received data. Discarding the message. This may occur when

items have been deactivated.

Ø The following logger messages can occur in normal operation mode if log all is

selected in the logger settings. These messages show all of the servers activities.

Note: it can slow down the servers performance.

• New <data type> value: <value> for item: <item name> on <topic name>

An item was updated with a new value from the PLC.

• Write complete item: 0

A client has initiated write operation and the server signals the processing of poke

values by setting the "write complete" item to zero

Ø The following logger messages can occur in normal operation mode if "show

protocol" is selected in the logger settings. These messages show the sent and

received messages. Note: it can slow down the servers performance.

• PROTOCOL: <calling function name> dumping s7 objects (containing

<number of items> items)

• index=<index in message> var_name=<message name> var_length=<variable

size>

…

dumps the all s7 objects of one message which are containing <number of items> items

For example:

PROTOCOL: s7_multiple_read_req dumping s7 objects (containing 20 items)

index=0 var_name=DB223,B280,24 var_length=24

index=1 var_name=DB223,B320,1 var_length=1

index=2 var_name=DB222,B8,18 var_length=18

• PROTOCOL: <receive function name> dumping [read/write] values

• <S7 name>: result=<message result>, value=<HEXASCII value>,

var_length=<variable size>

…

dumps the all s7 objects of one cyclic, read or write message which are containing items.

For block items the whole block is dumped. This could seriously affect your servers

performance.
