• Receiving process typicals
(Cmd01B_R, Set01W_R, Par12D_R)
Set the parameter to 0 when the typical can receive data from more than
one partner, for example, when there are several control centers wanting
to send data to the typical configured here.
If the PLC receives a message for the object set here, and PartnerNo is
greater than 0, the system checks whether the source subscriber number
in the message is identical to the PartnerNo set here. If they are different,
the received information is discarded. An error message to this effect is
entered in the diagnostic buffer (event ID B130).
This check is not made if PartnerNo = 0. Regardless of the sender, each
message addressed to the object is also passed on to the object.
If the set PartnerNo is greater than 0 and this number was not found in
the administration (in DB-BasicData), an entry is made in the diagnostic
buffer (event ID B101). The CPU does not change to STOP. The FB is
then no longer processed, however, until the parameter assignment error
has been corrected.
Caution
If "PartnerNo = 0" is set, make sure that each partner sends the message
with a complete destination address (target subscriber no. and target
object no.).
Note
When using the block in the PLC of a node station, you should consider
the consequences of PartnerNo = 0 If the PLC of the node station
maintains both connections to higher-level subscribers as well as to
lower-level stations, a message with PartnerNo = 0 is transferred to all
subscribers both "up" and "down".
