Step 3: Connecting DP
1.
Connect the left DP interface on ibaBM-DP with the DP interface of your S7 PLC.
2.
Activate the DP termination in the PROFIBUS connector, if the device is the last in
the DP line.
3.
Download the system data to S7-PLC with HW Config and start the PLC.
As soon as the connection between the DP master and the slave(s) has been estab-
lished via the PROFIBUS line the “Bus“ LED should light yellow and the “Active” LED
white.
Step 4: S7 test program
1.
Generate a DB11 (or any free DB number) in your S7 project.
Fig 110:
DB11 contains 120 byte data for DPM64
2.
Define the local variables and call up FC105 and SFC15 (both blocks from S7 stand-
ard library) in OB1 or any other FC.
The scaled temperature (0.0 - 700.0 °C) is saved as a REAL value
in DB 11.DBD8 (the first memory range for analog signals)!
