Hello Alessio, I have not tried this with H systems, but i will suggest to use B_Send B_RCV blocks, i have used them when i exchange data between S7 300 controllers with integrated PN port (i think AG_Send is only suitable for CP's). Also i remember that For S7400 you have to use SFB_13(B_Send) and SFB_14(B_RCV), and for S7300 you have to use FB_13(B_Send) and FB_14(B_RCV). You can find both in your S7 Standart Library :). Finally i suggest to take a look to this manual: Attachment20982954_SIMATIC_Comm_DOKU_v201_e.pdf (297 Downloads) |
Keep working! |

Hi For communication using onboard PN port of PLC you can use only S7 Connection. This in turns limits you to PUT/GET option and BSEND/BRCV.
Using PUT/GET you can communicate between two PLC's using these instructions in any one of the PLC. Because PUT writes in defined area of the partner PLC and GET reads from the defined area of the partner PLC. You have to define connections in NETPRO. In case you have CP then others options are: You can use AG-SEND/AG-RECV on 300 and AG-LSEND/AG-LRECV on 400. You need to define the the connections in NETPRO. Still you have may other options.

Minor correction, S7 communciation based USEND/URCV are also available. More importantly though,you can also use the CPU's PN for ISO-on-TCP, TCP and/or UDP protocol based communciation via the so called "open IE communications" (i.e. TCON, TSEND, TRCV etc.) and the FAQ Which types of connection/protocols do the S7-300/400 CPUs and the CPs support by default? has more info on this. I hope this helps |
Cheers |
