Hello Sabine, I have three FC's: FC86 and FC87 are DP_Send and DP_RECV In FC85 is the following: Call "Transmit to DP Module" /FC87 CPLADDR :=W#16#170 RECV:= P#DB5.DBX10.0.0 BYTE 32 NDR := DB85.DBX1.0 ERROR:= DB85.DBX1.1 STATUS:= DB85.DBW2 DPSTATUS:= "DP module buffer".STAT[4] / DB85.DBB4 Call "Recieve fromDP Module" /FC86 CPLADDR :=W#16#170 SEND:= P#DB5.DBX70.0.0 BYTE 32 DONE:= DB85.DBX5.0 ERROR:= DB85.DBX5.1 STATUS:= DB85.DBW6 DB85 is the DP module buffer: +0.0 STAT0 ARRAY[0...9] *1.0 BYTE +10.0STAT1 ARRAY[10..60] *1.0 BYTE +62.0 STAT2 ARRAY[61...69] *1.0 BYTE +72.0 STAT3 ARRAY[70...125] *1.0 BYTE =128.0 END_STRUCT These blocks are called in the S7-300 program. The S7-400 program is completely empty. Very strange... Also, the pc's were stolen, so I don't know anything about the cards that were used in the PC's. Can the PC be used as master as wel?? One question: A profibus cable is going from the MPI(x1) port of the 400 to the PC but also the profibus cable from the CP443-5 adapter goes to the PC. There are two cables were the PC used to be.(the two pc's were stolen). The PC could be configured as een ES station but I don't knowwhy there aretwo connections |

Hello guys, I'll add a digital drawing of the field bus loop. This is a part of the drawing. The name PLC AB10-3 stands for the CPU416. The red lines are MPI, the green lines are Profibus and the blue line is optic fibre(red) Maybe this will clarify the whole configuration. The answers you gave me are clear to me... |

EDIT:A profibus line from AB10-3 goes to a number 2, that profibus line is the IM467 module for connecting frequency drives |
