data exchange, Data block
I have not used ABB PLC programming software. However, I have used Siemens PLC software. Pardon me when I used Siemens software as my reference to my questions regarding ABB plc programming. When I need to pass data back and forth between S7 plc, I use Datablocks (DB) to read from and store data between PLC-A to PLC-B and vice-versa. What is the equivalent in ABB PLC programming when exchanging data between two ABB PLC?
There is no equivalent to datablocks. Instead it is much easier.
To transfer data between AC800M applications, send the data using the same variables that your program uses. Variables can be sent using IAC (just a configuration setting on the variable declaration) or MMS ( a separate communication program that you need to write)
