Error In TIA but not in Step 7 GET/PUT

Thanks gents for the help.
I am on my way to site. Will let you know how I go.
I need to set up comms between
S7 1516 <--> S7 1512
S7 1516 <--> S7 315F
and probably more.
:geek:
 
Did not use the FB1 which I previously used with Step 7.
Used just separate GET PUT instructions and it worked between 1500 to 1500.
I need to set up comms to a S7 315 in two weeks time.

Thanks again for your help gents.
 
You need to use GET for the 1500 CPU. Access to system block parameters like GET via indirect addressing is not supported (as far as I can see) as they have probably been coded with optimised memory access. Copy your anypointer data into some temp variables and pass them to the GET block.

e.g.
Yes you are right. It's not supported in 1500 CPU.
This same FB1 works well with 315 CPU.
And it's used through out the plant for comms.
I would love to use the same for 1500 as well.
Do I need to replace network 1 with what you suggested?
I don't fully understand this indirect addressing with Siemens.
Can you please help me with this.
Your help is much appreciated.
 
I changed NW 1 as you suggested. See attached
Hope I got it right.

Now I get FB 1 area length error when I start the CPU and goes into STOP mode.
Internal address details: Caddr=16#0000003B, area: LD area, addr: 44

Please see attached for error info.
I am using this FB between a S7 1516 and a S7 1511
 
Not right. Go back to post #13 and see my code. For clarity, delete your existing code, don't comment it out.
 
Thanks L D[AR2,P#0.0].
I used separate GET/PUT instructions to transfer data not the function block.
Set up Local and Partner using tool chest and it works fine.
1500 needed to be the master for 315 in TIA not 315.


But I will try FB1 once more when I go to site next week.
Thanks for your help.
