13.4.1 The first Test
13.4.1.1 SIMATIC S7 Application unidirectional (S7-300)
An analog value (e.g. a temperature scaled with FC105 from S7 standard library) is to
be transferred as a REAL variable from S7-PLC to ibaBM-DP and acquired with ibaPDA.
Fig 108: Connection between ibaBM-DP and ibaPDA
Step 1: FO connecting and cabling
Because ibaPDA is a passive application and thus only reads data from the PROFIBUS,
the modes 0, 1 and 3 are available.
1.
Connect the fiber optical transmitting link (TX) on the ibaBM-DP with a receiving link
on the FOB card in the ibaPDA-PC.
2.
Start the ibaPDA software and define a module “ibaBM-DP-64” in the I/O Manager of
ibaPDA.
3.
In the ibaPDA I/O Manager, mark the corresponding link under the FOB card in the
signal tree.
Without being connected to the PROFIBUS line, the ibaBM-DP should send valid
telegrams to ibaPDA. Using the diagnostics of ibaPDA you should be able to watch
the telegram counter running.
As soon as the connection between the DP master and both slaves of ibaBM-DP has
been established the “Bus” LED should light yellow and the “Active” LED white.
Step 2: GSD file installation and hardware configuration
1.
Start the “HW Config” tool in the current S7 project and install the GSD file named
“ibaF04n3.gsd “.
2.
In the web interface of the ibaBM-DP, set the operating mode to mode 3 (PDA 28
Reals).
3.
Open the “PROFIBUS DP” folder in the hardware catalog of "HW Config".
4.
Connect an ibaDPM64 module with the PROFIBUS line per drag & drop and set an
DP address (in the example 10) for this module.
Important note
The same address has to be set in the web interface of ibaBM-DP!
5.
If you want to use both slaves in ibaBM-DP, connect another module to the PROFI-
BUS line and assign the other address configured in the web interface of the device
to this module in the “HW Config” program.
