tracking

Hello,

How do you set the track enable option to True in a PID block. Im trying to initiate the TRK_IN_D to True, so that the TRK_VAL goes to the output.

    Modify PID/CONTROL_OPTS and enable the box by 'Track Enable'. And you may want to confirm the 'Track in Manual' option as well.

    Where do I find PID/CONTOL_OPT and the 'Track Enable'. I know I have to do this, but I don't know where. Is it in the PID block itself in control studio or in the PID faceplate?

    In reply to garlanov:

    It is accessible from control studio by clicking on the PID block and then double clicking control_opt in the parameter window. This parameter must be changed off-line and downloaded (when a download will not disrupt the process).

    In reply to Chris:

    Yes thanks. I actually found that, but your correct you need to put the block in Out of service which will disrupt the process

    Garlanov,
    You "enable" the Tracking feature via the PID/CONTROL_OPT as Chris says. This can be done on a download or by setting the MODE to Out of Service (a brief time in OOS does not usually disrupt the process) . This only needs to be done once. Then you set PID/TRACK_IN_D to True to set tracking of PID/TRACK_VAL to the PID/OUT and False to not track. Books on line has an example of this application.
