Hello monir; Have a look at the following sample program for PUT/GET exchanges between S7-300 CPUs, you should find it enlightening. https://support.industry.siemens.com/cs/ca/en/view/18610307 Hope this helps, Daniel Chartier |

HEY that is easy when you use PUT in the local CPU with address p#m0.0 byte 4 , that means you will send the data to remote cpu in area starting m0.0 and counting 4 bytes after that byte 0, byte 1, byte2 ,, byte3 . no need to do anything in the remote cpu just make a variable table and watch the data transfering upon the request in the local cpu S7-1200 to S7-300 Plc Communication see this link may it help to understand the operation regardless of cpu version . regards ahmed hamad |
