Simulation mode
For general information about system integration and activating the simulation mode,
see chapters 7.3.4.5 and 8.6. If you want to use the simulation mode, you need an addi-
tional license (order information, see chapter 2).
14.1 Commissioning procedure
1.
Configure the PROFIBUS master and start it, even when not all configured slaves
have been connected.
2.
Connect the ibaBM-DP device to the PROFIBUS. Both connections X40: Bus0 and
X41: Bus1 can be used. This way, the slaves can be simulated by two different bus
lines.
3.
Switch on ibaBM-DP.
While booting, ibaBM-DP is searching for “missing” slaves. These are all slaves,
which are requested by the PROFIBUS master, but do not respond, as they are not
present on the bus. These physically missing slaves are simulated by ibaBM-DP.
Important note
Switch on the device only, after you have connected the connections X40: Bus0 or
X41: Bus1 to the PROFIBUS. Missing slaves are searched for and simulated only
while ibaBM-DP is booting.
4.
From now on, all displayed bus errors should disappear on the PROFIBUS master.
Since ibaBM-DP simulates all missing slaves, the PROFIBUS master detects the
configured slaves as being existent and valid.
5.
Start the simulation program and establish a TCP/IP connection to ibaBM-DP.
The following settings apply to the TCP/IP connection:
The simulation program is the “active” communication partner. Here, you have to
enter the IP address (or device name) and the port number of ibaBM-DP. You find
the IP address on the “Info” webpage in the web interface. The port number is
“999”.
You can define a “send” and “receive” telegram for each slave to be simulated.
The receive telegram contains the data, the master sends to the slave (outputs).
Within the send telegram, you can simulate the data the slave sends to the mas-
ter (inputs). The telegram structures are explained in chapter 14.3.2.
14.2 Boundary conditions
ibaBM-DP searches for missing slaves only when the device is booting. Subse-
quent changes of the configuration like adding or removing slaves are not detected
by ibaBM-DP. Only after a restart of the device, by switching on and off, ibaBM-DP
searches for missing slaves.
Any number of slaves can be simulated. The limitation of ibaBM-DP to 8 active
slaves does not apply to the simulation mode.
In simulation mode, you generally cannot acquire simultaneously data from the
ibaBM-DP in ibaPDA via FO cable.
