ibaBM-DP
Manual
Issue 1.7

If ibaPDA is available, you can use it for diagnostic purposes. The ibaPDA-PC has
to be equipped with a ibaFOB-X or ibaFOB-D card.
Additionally you need:
a network connection between the ibaPDA-PC and ibaBM-DP and
an unused link on the ibaFOB-X or ibaFOB-D card
ibaBM-DP does not need to be connected via a fiber optic cable to this unused link.
The diagnostic can be used only by temporarily adding ibaBM-DP to the I/O configu-
ration.
Insert an ibaBM-DP device on the unused ibaFOB link, activate the compatibility
mode 32Mbit in the "General" tab and parametrize the IP address or device name of
ibaBM-DP. In the "PR
OFIBUS
browser" tab you can now see the status of the simu-
lated slaves and analyze the output and simulated input data.
14.3 TCP/IP protocol
14.3.1 Telegram data transfer
Slave data is transferred to ibaBM-DP via TCP/IP at port 999.
The telegrams sent
to
ibaBM-DP
are referred to as
request
in this manual, the tele-
grams sent
from
ibaBM-DP
as
response
.
The input data is sent to ibaBM-DP with a request telegram. ibaBM-DP takes over the
data and returns the output data of this slave with a response telegram.
The request telegrams are processed sequentially, i.e. it is not necessary to wait for a
response after a request, before sending further requests.
Possible procedures:
Procedure 1 (synchronous)
Request 1
Response 1
Request 2
Response 2
:
Request X
