Receiving process typicals
(Cmd01B_R, Set01W_R, Par12D_R)
Programming 0 is necessary in the following situations:
– The partner is not an S7 CPU, i.e. there is no DB number as object.
This is, for example, the case when the partner is an ST7cc control
center.
– There is more than one partner (PartnerNo = 0) from which the typical
is to receive data. The corresponding objects of these partners will then
generally have different numbers; in other words, no unique number
can be specified here.
If the CPU receives data for the object programmed here and
"PartnerObjectNo" is > 0, there is a check to establish whether the source
object number in the data frame is identical to the "PartnerObjectNo"
programmed here. If they are different, the received information is
discarded. An error message is entered in the diagnostic buffer (event ID
B131).
This check is not made if "PartnerObjectNo" is = 0. Regardless of the
sender object, each data frame addressed to the object is also passed on
If processing is enabled, all the functions of the block execute.
The response is different if processing has not been enabled:
