Introduction

Sniffer function

Due to the sniffer function, ibaBM-DP can read all data sent on PROFIBUS DP (cyclical data exchange according to DP-V0). The device only needs to be connected to the PROFIBUS. The device does not need to be configured as a PROFIBUS slave in order to use the sniffer function.

The acquisition of slave-to-slave communication (DP-V2) is not supported.

Active slave

Up to 8 slaves (extension to 16 slaves is possible with additional license) can be activated on the ibaBM-DP bus monitor. The maximum output data range of each slave is 244 bytes, which can be written by the master. Active slaves have to be configured by means of the provided GSD file. The active slaves can be distributed to both PROFIBUS connections. The sniffer function and the active slaves can be used simultaneously.

Redundancy mode

With the redundancy mode option, ibaBM-DP can read and acquire data on redundant PROFIBUS lines on S7-400H control systems, both as sniffer and as active slave. ibaBM-DP monitors the telegram traffic on both PROFIBUS lines and dynamically detects, over which line valid data are currently being sent that are recorded with ibaPDA. This procedure offers the advantage that data do not need to be acquired twice.

ibaBM-DP immediately identifies error situations such as the switching of a CPU to STOP, the failure of a slave connection or broken cables and automatically switches to the intact bus system.

P2P mode

The P2P mode (peer-to-peer) enables a bidirectional system interconnection via PROFIBUS with iba devices with an ibaNet 32Mbit interface (e. g. via ibaLink-VME to VME-based control systems). For this purpose, the data from the ibaNet interface are mapped on up to 8 PROFIBUS slaves.

Simulation mode

With the simulation mode option, software and the configuration of a DP master station can be tested without the need for a peripheral system of the PROFIBUS to be physically present. This means, for example, that a new control program can be tested in a test environment. This way, expensive down times during commissioning can be reduced.

The PROFIBUS slaves that have been configured in the master, but are not physically present, are simulated on the device. It is not necessary to carry out a PROFIBUS configuration in ibaBM-DP, since the device evaluates the configuration telegrams from the master and creates the corresponding slave automatically.

The input values of the slaves are simulated using a TCP/IP telegram interface and the output values are requested. This TCP/IP interface for simulating the system can be used with any tool (e. g. ibaLogic).

The simulation mode is approved for the use with PROFIBUS masters supplied by Siemens only.

Mirror mode

The mirror mode option is ideal for modernizations in which a new control system is to run in test mode parallel to the current system. With a PROFIBUS connection, ibaBM-DP is coupled into the original PROFIBUS line. The second connection is connected to the new control system. ibaBM-DP mirrors and simulates the slaves from the original line to the parallel system. The input data are also copied. This way, the new controller can be tested in parallel with the original slaves and real input data. Signals from the original and parallel system can be recorded and compared simultaneously with ibaPDA using the sniffer function.

Mapping mode

The mapping mode provides extensive possibilities to exchange data between two PROFIBUS systems connected to Bus0 and Bus1 interfaces. This option is suitable for modernizations but also for plain data coupling on a PROFIBUS level. A classic DP-DP coupler is available for transfer of output data of one slave to the input data range of an assigned slave in a bidirectional way. In addition the output data of existing slaves of the PROFIBUS system Bus0 can be sniffed and transferred to the input data range of an assigned slave. In total up to 8 of these mapping assignments can be used (when using the expansion of active slaves even 16). The functionality of the mapping mode therefore offers much more than just a classic DP-DP coupler.

Overview of the most important characteristic values:

• Bus monitor for PROFIBUS DP

• Connections for 2 PROFIBUS lines up to 12 Mbit/s

• Sniffer function for interference free acquisition of the cyclic master slave communication (DP-V0)

• Up to 8 or 16 active slaves¹ can be configured; can be distributed as required on both connections

• Acquisition of up to 244 bytes per active slave

• Flexible configuration of sampling rate, data format and data volume

• Support of ibaNet protocol 32Mbit Flex: Transmission of configuration and measurement data via bidirectional FO connection

• Compatibility mode 3Mbit and 32Mbit allows the exchange of previous devices ibaBM-DPM-S and ibaBM-DPM-S-64

• Request procedure can be used with ibaPDA for SIMATIC S7, FM458 and TDC

• For special applications, additional operating modes such as redundancy mode, simulation mode, mirror mode, mapping mode and P2P mode are available.

  Additional licenses are required for redundancy mode, simulation mode, mirror mode and mapping mode.

License model

Additional licenses are needed for some functional expansions:

• Expansion of active slaves on the device from 8 to 16

• Redundancy mode

• Simulation mode

• Mirror mode

• Mapping mode

Note
	Licenses for functional expansions are tied to the serial number of the device. The licenses are activated via the web interface of the device or via the I/O Manager in ibaPDA by entering a license key. For buying a license key for one or more functions, please contact iba AG.
