ACS 800 control with 800xA via profibus.
Hi Dear Experts,
We created 800xA DCS System and we communicated ACS800 Driver with profibus. We use drivestatus and drivecommandsend function blocks.
when we start on local mode we can see running, ready feedback.
When we get to the remote we can see remote feedback but we cant send start command or reset command to driver.
I add attachment function blocks in online mode. How can i send start command or set point value.

Configuration of the values that you want to read from the drive is done within the ACS, i.e. if you want current on Act3, then set parameters in the ACS. I don´t remember the exact parameter, but it´s there somewhere.
The same applies to reference values. Configure (in ACS) which Ref-value you want to act as reference for the drive.
You're trying to start the ACS without any of the three least significant bits set. They represent Off1 (ramp stop), Off2 (coast stop) and Off3 (selected stop type). Depending on what you want to achieve, set at least one of them (or all). Stop type is set in parameter 21.3, if I´m not mistaken...
As you can see, the status is 512 (Bit9) which indicates remote mode, but you're lacking the ready signals bit0-bit2.
