Hello,
I want to send from PLC (315-2 PN/DP CPU) 5 word values (10 bytes) to one WinCC raw data tag using FB12 "BSEND". I don't have physical the PLC, so I use PLCSIM.
The problem I have is that error and status have value 1. I know that the issue could be one of the following:
“Communications problems, 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: maximum number to parallel jobs/instances exceeded”
In WinCC on raw data tag's address I have selected "BSEND/BRCV" option and I set R_ID to 15.
The DB associated to FB12 call and the function where I call FB12 have been downloaded to PLCSIM. Connection between PLCSIM and WinCC works fine.
What am I missing?
Many thanks in advance!
