CVS Posts: 10 Rating: (0)	Dear Experts, I am new to this field. I am trying to communicate between two CPU 315-2DPs with cp 343-1 in the same project. I have tried with put and get funtions, I am not able to get connected. Igot no errors in netpro compiling. When i checked the instance db of get or put function blockI got error 0 status 19 or 1, it is blinking. I could not understand what would be the problem. I have searched this site and got some helpdocumentationon PUT/GET, basing on that I tried to implement for these cpus. But could not succeded. I also tried with send and rcv blocks also then i got error 1 and status 1. I have attached the trail project here. Anticipating your help.. Thanks in advance.

Regards, CVS Hello CVS, Have you seen this FAQ How do you program communication blocks FB14 "GET" and FB15 "PUT" for data exchange in the S7 program of an S7-300 CPU? Also How do you program communication blocks FB12 "BSEND" and FB13 "BRCV" for data exchange in the S7 program of an S7-300 CPU? CPU-CPU communication with SIMATIC controllers (compendium)

I hvae very little bit idea over network configuration regarding communications.I don't know what would be the error in my code. Regards, CVS Hello CVS, As per Your Error code on the Put get Means, Communication Problem, For Example: - Connection description not loaded (local or remote) - Connection interrupted (for example:Cable, CPU off, CP in stop mode) - Connection to partner not yet established. - FB cannot be run on an S7-400-CPU - Also for S7-300 : Max. no to Parallel Jobs/instances exceeded. Also let me know you are getting code 19 in Dec or Hex ? as per 19 Hex it is 25 in Dec. so Communication has started, job is being processed. you will get all this information on the Block Help.

Eastern Posts: 557 Rating: (64)	Hello, In netpro you can monitor s7 connection. save as diagnostic buffer of CP's & attached it. I saw your program seem like ok. check phycial connections. trigger ip address & first check connections are ok.
