Dear All,

                 I also, Facing some configuration problem with ABB's  MNS-iS.

                My hardware configuration has shown in attachment.

               I am not able to read & write consistent data  i.e. 244 byte read & 124 byte write with SFC 14 & SFC 15. It is wotking for 4 byte only. If i increase the data beyond 4 byte then it will show length miss match error.

               Reading of consistent data with this configuration is possible or not?

hi Mahesh,

as I´ve seen on your picture, your data are only consistent over unit. I´m wondering that you are able to do it with the length of 4 byte.

let´s try to read out one whole input-slot, e.g. the first from 512..575 with a length of 64bytes. the destination-area should have a length of 64 bytes too. 

maybe it doesn´t work, because it is not consistent over total length in HW-config. 

for further help please tell us what Error-Code is in RET-VAL?

Yes,

        I am also thinking the same.

      When I do configuration with universal & programmed which is shown in attached picture.

      Then its work.

New question published by Mahesh N is split to a separate thread with the subject S7-400 & ABB's Imcc M-Link on profibus.
