More than 1 inverter connect error BF coming

hi, everyone

i got problem, when i'm programming with 1 inverter the PLC normal. but if i'm add second inverter, error /alarm incoming (a1920)/ cycle intrupt connection. i connection with profibus.

what i must doing, for the setting inverter/PLC??

Thx. Best regard

yes, the 1st inv adrres is #10

and then the 2nd inverter #11

or

what the parrameter must be sett?

yes,i change connector, replace cable and still coming A1920

and do you now what the mean

Remedy:
Establish the PROFIBUS connection and activate the PROFIBUS master in the cyclic mode

Do you have selected PROFIBUS addresses10 and 11 for the drives in the hardware configuration?

Do you have made a FB, to create control word and setpoint?
If yes, do you call it twice, and each time with a own instance DB (or with a own multi instance).

not yet miami. i'm not yet create fb. because i can't. so i'm to much ***.

can made an example for that?? please

dpends which inverter you use, normaly the adress is set with the dip switch on the device.

have you also check the wiring and termination of the DP connectors/Cables?

 if connector in PLC made off, connection succes only 1 inverter and another plc A1920. but if on position connector plc, all inverter alarm A1920. so what i must doing?

Please Help me....
