Aktive slave – General tab

In the General tab, make the basic settings, advanced settings and PROFIBUS settings for the "Active slave" device module.

Basic settings

Locked, Enabled, Name, Modul No., Timebase (only display), Use name as prefix

see chapter ibaBM-DP – General tab.

Advanced

No. analog signals

Defining the number of analog signals for this module (min. 0, max. 512).

No. digital signals

Defining the number of digital signals for this module (min. 0, max. 512).

PROFIBUS

Bus number

Define here, on which bus system (Bus0: X40, Bus1: X41) you want the active slave to be generated.

Slave number

Please define here the address of the active ibaBM-DP slave.

Command for browsing the PROFIBUS

Browse profibus

This command opens the Profibus browser, which can be used to interactively add signals from the input and output data area of the slaves to the analog and digital signals. See also chapter Signal selection in the Profibus browser.

Caution!

Connecting the PROFIBUS cable

A conflict between several slaves with the same number can lead to a complete failure of communication on the PROFIBUS and even to a system shutdown.

To ensure that there are no duplicate slave numbers, do not connect the PROFIBUS cable until the configuration of the active slaves has been correctly carried out in ibaPDA.

Note

By adding more modules of the "Active slave" type, you can generate more slaves on ibaBM-DP.

By default the max. number of active slaves is eight. If you define more active slaves, an error message will appear. If you need more than eight active slaves, please do not hesitate to contact the iba support. You can increase the number of active slaves to 16 with an additional license.

Note

Only define slave numbers for the device that are not yet existing in the PROFIBUS line. Select exactly these addresses that you have defined in your control configuration (e. g. SIMATIC® Step 7 Hardware Configuration) for the active slaves.

Before ibaBM-DP activates its own active slaves, the device first checks whether there are already slaves with the same number on the bus. If a slave with the same number already exists, your own slave is not activated.
