Communication between DCI and AC800M processors
Is there a way to share values between a DCI cpu and AC800M cpu? These cpus are on separate control networks but are parts of a common 800xA system. Thanks!

You can use Property Transfer function.
The Property Transfer function is mainly used to transfer data between OPC servers.
It can also be used as a calculation function, not only reading data from aspect
object properties but also entering these data into a suitable algorithm and delivering
the results to aspect object properties.
The data collection as well as the data delivery can be done from/to any public
aspect object property (including the aspect properties from aspects such as the
General Properties aspect).
Hope this will help.

Hi. Arguably there are several methods. One most favour, is using Profibus (with 3rd party bridge), as this is supported by both systems. Another is via OPC, but this might be for "non-critical" signals: also needs something like OPC data link, so that two OPC server can have data passed between them. Obviously the common method is with Modbus (serial), but this is a little more insecure than the abovenamed options.
