Delta V 12.3 communication with siemens S7-300 DP/ DP COUPLER

Hi,

We are working on interfacing DeltaV system with a third party package comprising of Siemens S7-315 PLC. Profibus DP-DP coupler has been utilised for interfacing these two masters (DeltaV & Siemens S7-315) (FOR COPERION CONVEYING).

Below are the configuration .

He has configured the following data blocks

64 bytes in

16 bytes in

16 bytes universal

64 bytes out

16 Bytes out 

16 bytes universal


From our configuration side, we can only add the Profibus DP slots in the blocks of 1 byte, 2 bytes, 4 bytes, 8 bytes, 16 bytes, 32 bytes, 64 bytes, 64 words. (As I can see from the GSE File)
I think first slot starts at address 0 and there is no way to configure the starting address.( AT DELTA V FIRST 3 SLOTS ARE OF 0 BYTES FOR HOUSEKEEPING BUT UNABLE TO DO IT) 

The address map starts from 0 and can only go up to 243 bytes (inputs) and 0 ~ 243 bytes output. 

1) I am wondering how his addressing transform in to Profibus DP Slots and offsets configurations which are available in DeltaV? 
2) The GSE file showed me slots of 1 byte~ 64 words and it also showed me 1byte consistent ~ 64 words consistent. Can someone pleaseexplain me what does it meant by consistent?

3) AT DP/DP Coupler 

SF 1: Group error on PROFIBUS DP network 1 (red)

SF 2: Group error on PROFIBUS DP network 2 (red)

BF 1: Bus error on PROFIBUS DP network 1 (red)

BF 2: Bus error on PROFIBUS DP network 1 (red)


Many thanks in advance and kind regards Here i must need step by step help from both plc and dcs ends
