Hello, I am trying to exchange data between three plc´s that are part of a PCS7 system. It seems quite simple using blocks SEND_BO and REC_BO. However They haven´t worked properly since the commisioning of the system. Anyway, next week I have the chance to stop all the system during a whole day and I would like to stablish communication between my plcs, then I have attached a file that shows how the connections have been created in NetPro. Can anybody tell me if they are ok????? Once connections are setup properly, for example for communications between PLC1 and PLC2 is this correct: PLC1: SEND_BO (ID = 3 and R_ID = 23) PLC2: REC_BO (ID = 3 and R_ID = 23) PLC1: SEND_R (ID = 3 and R_ID = 24) PLC2: REC_R (ID = 3 and R_ID = 24) I suppose the ID should be 3 for all kind of communicatons between PLC1-PLC2 (send bools, reals, etc...) However R_ID should be unique for every connection. Is that correct?? Also, from which OB should be called those blocks???? Thanks for your help AttachmentCOMMs Between PLCs.pdf (239 Downloads) |

Thanks Zarepegro, I understand that the column "Pos" indicates the order in which the blocks are executed??? Is this correct? |
