Hi All
I need to index a Pointer in a RTU Modbus Master block, please see attached screen shot.
I have 34 VSD's which I need to Write the Speed ref to and Read the Statuses,
when I use an Absolute address (P#DB13.DBX0.0 BYTE 4) it works but not with anything I have tried using a dynamic address.
Any Ideas?
Thanks
