How to address the StartAddr of S3964RRead,S3964RWrite Blocks in AC800M Controlbuilder?
I am trying to establish communication between Siemens S7300 PLC with CP340(RS232C) and ABB AC800M using the Protocol S3964R.
I used S3964RConnect,S3964RRead blocks in my controlbuilder application.
If I enter the StartAddr as "%MW10#0" then i am getting the error "4054" in the S3964RRead block status.
If I enter the StartAddr as "ED4.0" then i am getting the error "-30" in the S3964RRead block Status.
In Siemens also I have done some programming and the variables needed for communication were declared inside Data Block "DB4".
So How to address the "DB4" in "StartAddr" of "S3964RRead" block
